Ever noticed those perfectly round holes dotting the dunes as you stroll Navarre’s shoreline? They’re not just “mystery sand pits”—they’re the doorways to ghost crabs, the tiny engineers that tell us whether our beach is thriving or stressed. Count their burrows for just 30 minutes, and you’ll collect clues scientists use to gauge dune health—all while giving the kids a real-life nature quest, adding fresh photos to your sunrise walk, or logging data for your next iNaturalist badge.
Key Takeaways
• Ghost crab holes are clues about how healthy the sand dunes are.
• Spend 15–30 minutes counting the holes to help scientists and learn about the beach.
• Lots of holes mean happy dunes; few holes can warn of storms, erosion, or too many people.
• Look for fresh holes at dawn, dusk, low tide, or a few hours after rain.
• Simple gear works: tape measure or jump rope, notebook, phone GPS, red flashlight at night.
• Kids can do a quick 10-meter count; bigger surveys add data to apps like iNaturalist.
• Walk on firm wet sand, don’t poke holes, and keep dogs leashed to protect crabs.
• Share your counts with #NavarreBurrowCount or the resort board to join the citizen-science project.
• The resort lends tools, gives guided walks, and has wheelchair paths so everyone can join.

Meet the Ghost Crab Up Close
Ghost crabs look like drifting shells until they sprint sideways, vanishing with a puff into the sand. Their pale bodies blend so well with the quartz grains that local kids call them “sand ghosts,” a fitting name for creatures that forage by moonlight and disappear by sunrise. Despite weighing only a few ounces, each crab digs year-round, aerating the dunes and recycling nutrients in ways bulldozers could never replicate.
Ecologists consider Atlantic ghost crabs keystone species, because their tunnels affect everything from sand moisture to the hunting success of shorebirds. A beach crisscrossed with fresh burrows usually signals stable dunes, low erosion, and minimal trampling. Sparse holes, on the other hand, can mean a recent storm, heavy foot traffic, or a shoreline starved of new sand—insights that help coastal managers focus restoration dollars where they matter most (Florida wildlife research).
Why Hole Counts Reveal Dune Health
Think of ghost-crab burrow density as a beach report card you can read at a glance. High counts mean the sand stays moist enough for safe tunnel walls, predators haven’t been overhunting, and tourists are sticking to firm wet sand instead of crushing the loose upper dunes. Low counts serve as early warning signs: maybe offshore currents have stripped sand away, or a string of busy holiday weekends pushed crabs into hiding.
Because ghost crabs are both predator and prey, their numbers ripple up and down the food web. More burrows signal plentiful insects for the crabs to feed on and reliable snacks for plovers and herons. Fewer burrows hint that the entire chain could be faltering. By jotting down the hole sizes you see today and comparing them with next year’s visit, you’ll help scientists track long-term trends without setting foot in a lab.
Prime Times and Sweet Spots for Spotting Burrows
Dawn and dusk are easily the best windows for observation. At first light, the sand is cool, winds are gentle, and most beachgoers are still sipping coffee. Crabs often excavate fresh pellets after a night of hunting, leaving textbook-perfect openings that haven’t been stepped on. Two to three hours after a rainfall is another goldmine: as the sand drains, crabs reopen flooded tunnels, pushing up tell-tale mounds that resemble tiny volcanoes.
Tide matters too. Aim for ebb or low tide to expose the widest strip of sand and reveal burrows near the swash zone. You’ll find the density peaks about 10 to 30 meters landward of the waterline—far enough to stay dry, close enough for the crabs to dart back to the surf if a gull swoops in. From the campground’s western gate, a relaxed 15-minute walk delivers you to a quieter stretch of dunes where footpaths thin out and burrows bloom like polka dots across the sand.
Kid-Friendly Counting in 30 Minutes
Give young explorers a jump rope and watch them transform into junior scientists. Lay the rope parallel to the shoreline so it measures roughly ten meters. Have the kids count every hole within one giant step (about a meter) on each side, calling out “pencil-wide!” or “thumb-wide!” as they go. After they tally both sides, jot the total plus time of day in a notebook, then challenge them to repeat the process after lunch to compare results.
This quick transect fits easily between sandcastle sessions. It teaches estimation, observation, and stewardship all at once—no screen time required. Parents love that the exercise burns off energy, while kids love naming the biggest burrow “Monster Crab HQ.” Pro tip: let the youngest child hold the clipboard; they’ll feel like the official record keeper and stay engaged the entire walk.
Level Up: Full Citizen-Science Protocol
Ready to add your findings to global data sets? Slide a meter stick, biodegradable flags, and your GPS-enabled phone into a daypack. Starting ten meters up from the waterline, run a thirty-meter tape measure parallel to the surf. Record every burrow within one meter on either side, noting diameter using the “two-finger rule” (about three centimeters). Flag jumbo holes so you can photograph them with a scale, then upload both images and numbers to iNaturalist before heading back for lunch.
A few extra details sharpen your submission. Log weather, tide stage, and time, since these factors let researchers compare apples to apples when merging your data with other coastlines. If you’re worried about signal strength, good news: the resort’s Wi-Fi blanket reaches the dunes, so you can sync photos in real time without burning mobile data. Even a single transect enriches regional conservation studies run by Gulf-coast universities.
Low-Impact Field Etiquette
Ghost crabs survive because their sand palette hides them from predators—don’t undo that camouflage with careless steps. Stick to the firm, wet sand whenever possible; the upper dunes look inviting, but one heavy boot can cave in a nursery tunnel. Night explorers should swap harsh white beams for red or amber lights that protect both crabs and nesting sea turtles.
Tempted to poke a stick down a hole? Resist. Crabs usually retreat deep—up to a meter—and can suffocate if the tunnel collapses. Pouring water is a similar no-go; the sudden flood forces them to expend energy digging out, possibly missing a crucial feeding window. Finally, leash your dog below the dune line. Pup-powered digging can level a night’s worth of crab architecture in seconds, leaving both habitat and data in ruins.
Gear Checklists for Every Traveler
Families thrive on simplicity, so pack a sand-safe tape measure, child-size clipboard, reef-safe sunscreen, and bite-size snacks. The clipboard keeps papers flat when the sea breeze kicks up, and snacks ward off “I’m hungry” meltdowns halfway through the transect. A zip bag of colored pencils lets kids shade in burrow shapes during downtime.
Retiree snowbirds may prefer comfort over speed. A lightweight folding stool offers quick rests, while a wide-brim hat and refillable water bottle fend off midday rays. Many guests also bring compact binoculars to watch herons snatch unlucky crabs, adding a relaxed bird-watching angle to the outing. Because you’re here for weeks, consider an inexpensive solar charger to keep phones topped up on long beach days.
Outdoor adventurers often think gear first, so slide an action camera onto your hat brim for hands-free footage. Keep a field notebook waterproofed in a resealable pouch and stash a spare battery pack in case live streaming drains power. A pocket-size solar panel draped over your backpack means you can map burrows sunrise through sunset without hunting outlets.
Educators and homeschool leaders operate at group scale. Pre-printed data sheets streamline instructions, and pencils on strings prevent the inevitable beach-wide scavenger hunt for dropped supplies. Color-coded flags help assign sections to teams, while a compact first-aid kit covers inevitable shell nicks or sunburns. Don’t forget a clip-on hand sanitizer—nothing ends a lesson faster than gritty PB&J fingers.
Accessibility and Safety Notes
Not everyone tackles sand the same way, so the resort maintains a beach-wheelchair path that reaches firm ground where burrow density remains high. From this point, a half-mile loop offers benches every 150 meters, perfect for grandparents pacing themselves or guests rehabbing knees. The terrain is mostly flat, letting mobility-aid users survey crabs without tackling steep dunes.
After heavy rain, swap flip-flops for water shoes with grippy soles; wet sand can be surprisingly slick. For children under ten, we recommend one supervising adult for every three kids—curiosity often outruns caution on an open beach. Always carry water and check the UV index; cloud cover in the morning can vanish by 10 a.m., turning mild strolls into sun-soaked treks.
Resort Perks to Boost Your Count
Before stepping onto the sand, swing by the front desk and borrow a measuring tape, red-lens flashlight, or printable worksheet—free for registered guests. Pin your results to the community bulletin board by the pavilion, and you might earn a shout-out during Thursday’s sunset “crab chat” around the fire pit. The informal gathering blends marshmallow roasts with conservation talk, letting newcomers swap sightings with seasoned snowbirds.
Staying the month? Extended-stay discounts include two guided dune walks led by staff naturalists who share insider tips on reading claw prints and estimating crab size from opening width. Large groups can reserve covered picnic tables near the south lot: restrooms, bus parking, and a freshwater tap for rinsing sandy feet sit within fifty yards, easing logistics for field trips and family reunions alike.
Classroom and Homeschool Resources
Planning a lesson that travels home in sandy sneakers? Download our K-8 worksheet aligned with Florida science standards; it covers crab anatomy, food-web roles, and a mini-quiz on erosion. A leave-no-trace pledge sheet—complete with kid-friendly icons—encourages students to sign their names before hitting the dunes, reinforcing stewardship through commitment.
Teachers can schedule weekday ranger talks by emailing the address listed on the worksheet, with a cap of twenty-five students to keep the experience interactive. Buses unload in the south lot, where a shaded lawn lets classes review safety rules without crowding the public boardwalk. By day’s end, each student leaves with a data sheet, a selfie beside their favorite burrow flag, and a new appreciation for sand that’s very much alive.
Share, Compare, Repeat
Citizen science shines when data remain in motion. Tag your photos with #NavarreBurrowCount so fellow campers, teachers, and retirees can compare notes across seasons. Over time, these snapshots build a living archive, revealing whether burrow density rebounds after a quiet winter or dips following a stormy hurricane season. The resort reposts standout images, turning your sunrise snapshot into next week’s inspiration for newcomers.
Seasoned visitors often jot last year’s numbers inside their travel journals, then flip back a page when they return the following spring. Seeing trends unfold under your own handwriting transforms a simple beach walk into an annual tradition—and a small but crucial piece of coastal stewardship.
So when the dunes call your name, bring your tally sheet—and your curiosity—back to Navarre Beach Camping Resort. From our private fishing pier and complimentary red-lens flashlights to guided naturalist walks and sunset campfires, everything you need for a family-friendly, low-impact “burrow safari” is just a few sandy steps from your campsite, cabin, or RV hookup. Ready to trade ordinary beach days for data-rich adventures that safeguard Navarre’s shoreline—and its tiny sand ghosts—for years to come? Book your stay today and start counting!
Frequently Asked Questions
Q: What’s the quickest kid-friendly way to count ghost-crab burrows, and how long will it take?
A: Borrow a jump rope or ten-meter tape from the front desk, lay it parallel to the waterline, and have the kids tally every hole within a giant step on either side; the whole mini-transect takes about 15–30 minutes, so you can squeeze it in between sandcastle time and lunch without anyone getting bored.
Q: Are the dunes safe for little ones, and is there a less-crowded spot we should aim for?

Q: I’m a retiree with limited mobility—how strenuous is the walk, and are there rest areas?
A: The resort maintains a beach-wheelchair mat to firm sand where many burrows are visible, then a loop with benches every 150 meters, so most guests can observe crabs at a leisurely pace and sit whenever they need a break.
Q: Does the resort organize guided nature walks or talks about ghost crabs?
A: Yes—registered guests can sign up at the office for twice-weekly morning dune walks led by our staff naturalist, and every Thursday evening we host a relaxed “crab chat” around the campfire where participants share sightings and ask questions.
Q: I’m an outdoor data geek—can I replicate the full mapping method without special gear?
A: Absolutely; a 30-meter tape, a meter stick, your phone’s GPS, and biodegradable flags are all you need to follow the same protocol researchers use, and if you forget something the front desk has loaner kits you can check out for free.
Q: Is there reliable cell or Wi-Fi coverage on the dunes to upload findings to iNaturalist?
A: The resort’s Wi-Fi mesh reaches the main study area, and cellular LTE is strong along the shoreline, so you can post photos and coordinates in real time or queue them for upload back at your campsite.
Q: Will counting or photographing the holes disturb the crabs or damage the dunes?
A: No—so long as you avoid stepping on the fragile upper dunes, keep dogs leashed below the burrow line, and resist poking sticks or pouring water into tunnels, the crabs stay unharmed and the habitat remains intact.
Q: When is the best time and tide to spot the most burrows?
A: Dawn or dusk at low tide is ideal because the sand is cool, footprints are minimal, and fresh overnight burrows near the ebb line are still crisp and easy to spot.
Q: Do I need to reserve worksheets or equipment before bringing a class or homeschool group?
A: For groups of ten or more, a quick email or phone call lets us set aside printed data sheets, clipboards, and flags, and ensures bus parking and picnic tables are waiting when you arrive.
Q: How does my simple hole count actually help scientists and conservationists?
A: Each tally adds to a regional database that tracks dune health over months and years, providing early warnings of erosion, storm damage, or human impact that guide where restoration money and protective measures are directed.
Q: Are there perks or discounts for snowbirds who participate in multiple counts during an extended stay?
A: Guests booked for a month or longer receive two complimentary naturalist walks, a 10 % gear-shop discount, and shout-outs on our community board if they submit weekly data, turning stewardship into a social activity.
Q: Can large school buses and field-trip groups be accommodated with restrooms nearby?
A: Yes—the south parking lot has designated bus spaces, adjacent restrooms, shaded picnic tables, and a freshwater tap, all within fifty yards of the boardwalk that leads to the counting area.
Q: Should we cancel our count if it rains in the morning?
A: Not necessarily; two to three hours after a shower is prime time because crabs reopen flooded tunnels, leaving fresh sand mounds that are even easier to identify and tally.
Q: Is this activity free for resort guests, and what basic items should we bring?
A: Participation and loaner gear are free for registered campers—just pack sun protection, water, and a notebook or phone for recording numbers, and you’re ready to go.
Q: Are ghost crabs dangerous to people or pets?
A: Ghost crabs are shy, palm-sized creatures that scuttle away from vibrations; they don’t bite unless handled, so as long as pets are leashed and kids observe rather than grab, everyone stays perfectly safe.
