Dog-Friendly Things To Do
Do something together
On the water & out in town
Dolphin cruises, kayak rentals, the Daufuskie ferry, a carriage through Charleston. The days out that will take the dog as well as you. 2 where they are welcome.

Bluffton
Captain Mark’s Dolphin Cruise
Dogs welcome
Family-run and openly dog-friendly: a well-behaved dog on a lead is welcome on the daytime dolphin watch, the sunset cruise and the crabbing trip.

Daufuskie Island
Daufuskie Island Ferry
Dogs welcome
The public ferry carries pets, and Daufuskie is about as dog-friendly as this coast gets once you land — all three restaurants have outdoor seating that welcomes them, and the island runs on golf carts rather than traffic. Leashed or under voice command.

Mount Pleasant
Carolina Polo and Carriage Co.
Partly
Lap dogs and service dogs ride the carriage; a labrador will not qualify. Ring ahead if yours is borderline rather than turning up hopeful at City Market.

Isle of Palms
Charleston Kayak
Partly
Dogs under 50lb on the rentals, but not on the guided tours — the distinction that catches everyone out. Bring a towel to protect the boat, and a life jacket for the dog if you are unsure how it will take to the water.

Beaufort
Coastal Expeditions at Downtown Beaufort
Partly
Same rule as the rest of Coastal Expeditions: rentals yes, guided tours no. The Beaufort river front is the gentler paddle of the two.

Beaufort
Coastal Expeditions at St. Helena Island
Partly
The guided trips are not dog trips, but you can rent a kayak and take the dog out yourself. No pet life jackets provided, so bring one.

Policies change and the host on the day has the final say. Call ahead if the trip depends on it.
