But Crab Bank isn’t just about conservation — it’s also famous for its fossil-rich sandbars and shark teeth, making it a must-see stop on any Charleston boat tour.

Crab Bank Island Tours — FAQ
What is Crab Bank Island and why is it special? Crab Bank is a small sandbar island at the mouth of Shem Creek in Charleston Harbor. It’s a protected seabird sanctuary and an awesome spot to explore nearby sandbars, walk the tide line, and look for shark teeth and shells—while we respect posted wildlife rules.
Do we actually land on the island? We follow state wildlife signs and seasonal protections. Your captain will choose a permitted nearby sandbar/shoreline so you can safely get out, beachcomb, and hunt for teeth without disturbing nesting birds.
Where do trips depart? Most trips leave from Shem Creek, Mount Pleasant. Your confirmation email has exact directions and parking tips.
How long is the tour? Typical trips run about 2 hours dock-to-dock (private charters can be longer). We time departures around the day’s tides for the best sandbar exposure.
What’s the best time to find shark teeth? Low tide is king. After a windy day or a big tide swing, fresh teeth often show up along the ripple lines and at the edges of shells and gravel.
How many shark teeth will I find? It varies by tide and luck—some guests find a handful, some find dozens. We’ll show you exactly where and how to look so you have the best shot.
Is this kid-friendly? Yes—this is one of our favorite trips for families. The walking is on packed sand with shallow water nearby. Keep little ones next to an adult at all times.
What should I wear and bring? Water shoes or sandals that can get wet, a small bag or zip-top for finds, hat/sunscreen, towel, and water. Light layers are smart in spring/fall.
Can I bring a stroller or cooler? Small soft coolers are fine. Strollers don’t roll well on sand—consider a baby carrier instead.
What about bathrooms? Some of our boats have a small marine restroom. If it’s important to your group, tell us when booking so we can assign the right vessel or advise.
Are pets allowed? We love pups, but wildlife rules and space onboard are limiting. Please ask before booking—pet approval is case-by-case.
Will I get seasick? Unlikely. We stay in protected harbor waters and near sandbars. If you’re sensitive, a non-drowsy remedy before boarding helps.
Is the walking difficult? We step off onto a sandbar with gentle slopes. Guests should be comfortable stepping from the boat into a few inches of water and walking on uneven sand.
What if the weather looks bad? Your captain monitors radar, wind, and tide. If conditions aren’t safe or fun, we’ll reschedule.
Can we keep what we find? You’re welcome to keep shark teeth and empty shells. Please leave live shells, sand dollars, and anything with a creature inside—and never disturb birds or posted areas.
Can I fly a drone? Drones are not allowed near posted sanctuary areas and can disturb wildlife. If you’re an experienced pilot, ask your captain first—most days it’s a no.
How many people can you take? We run small-group and private charters. Capacity depends on the boat assigned to your trip; tell us your headcount and we’ll match you to the right vessel.
Is this accessible? Boarding involves a step from the dock to the boat and from the boat to sand. If someone in your party needs extra assistance, let us know—we’ll plan accordingly.
Do you provide life jackets? Yes. Coast-Guard–approved PFDs are onboard for everyone; children 12 and under must wear them while underway.
Do you offer private trips or special occasions? Absolutely—birthdays, proposals, team outings, you name it. Tell us what you’re celebrating and we’ll make it easy.
