Founded in 1985, the Coastal Discovery Museum made a giant leap forward in the Fall 2007 when it opened the facility at Honey Horn. A Town of Hilton Head Island property, Honey Horn is home to several of Hilton Head Island’s oldest buildings. Since our grand opening, the Museum has expanded its offerings of programs, doubled the number of students that participate in Museum programs, and hosted dozens of special events and festivals.

The Coastal Discovery Museum is located at 70 Honey Horn Drive, Hilton Head Island, SC.

Marsh Tacky Horses

Possibly the most popular ‘exhibit’ at the Museum are the Marsh Tacky horses who live here. These horses are descended from Spanish horses that were brought here in the 16th century. Used by Gullah islanders for plowing, transportation and for hunting, these sturdy horses are making a comeback thanks to the conservation efforts of the Carolina Marsh Tacky Association. Comet spends most days in the fenced pasture on site while staying the nights in the historic Horse Barn, built in the 1930s. Be sure to stop by and say hello when you visit.

HorWaterfront Field Studyseshoe Crabs in the Classroom

Thanks to funding from the Bargain Box, the Coastal Discovery Museum has been able to offer a ‘Horseshoe Crabs in the Classroom’ teacher training program since 2011. Dozens of teachers have received the necessary equipment and materials to raise Horseshoe Crabs in their classrooms. Students are able to watch these amazing creatures grow throughout the year and then release them at the end of the school year.

Temporary Exhibitions

The Coastal Discovery Museum hosts 6-8 temporary exhibitions each year. These often offer an insight into local history and culture as well as the environment around us. We also work closely with several local arts groups to present art exhibits during the year. Check the schedule by visiting our Temporary Exhibits page.
