Enjoy a two-and-a-half-hour adventure on your own private boat. Your Master Captain will guide you safely through the Calibogue on a falling tide to the isle. This mile long sandbar is exposed for only a couple of hours per day, allowing beachcombers the chance to collect sand dollars, seashells and the occasional shark's tooth.
We’ll stop along the way to look for wild dolphins playing in the sound. We’ll share information about the island, the salt marsh and the surrounding ecosystem. Your Captain is also a Lowcountry Master Naturalist, and will assist you in identifying the various shells, mollusks and other invertebrates to be found on this tour!
This is an ideal outing for families and small groups. With up to 6 passengers, there’s plenty of room onboard and a comfortable seat for everyone.

Captain Mark was great. He knows the area and he was great with our teenage girls. We got to see many dolphins, learned about the ecosystem, and took home some sand dollars. Was the favorite part of our stay in Hilton head for one of the girls.

Such a wonderful tour! Mark was extremely knowledgeable of the area, and the local wildlife. He was great with kids, and spent time showing my 7 year old all the different sea creatures on the disappearing isle. We were able to collect sea shells galore. We will definitely be returning. I could not recommend this tour enough!

Core memories made! Captain Mark was so kind and knowledgeable! Our kids found so many sand dollars! We enjoyed seeing and learning about all of the wildlife and the history of the island. It is clear that Captain Mark loves what he does. I would reccomend this tour over and over! This is a one man business and not a huge corporation. Captain Mark knows his stuff and did everything to make our family vacation enjoyable!

We had a great excursion with Mark! Had fun finding shells and creatures on the sand bar and we spotted lots of dolphins. Mark shared a lot of info about the local ecosystem and even some about the real estate! He took us to a cool natural oyster shell heap as a little bonus on our way back. Definitely a more personal experience than a big boat with a huge group. Highly recommend!

Our adventure to the Vanishing Mile Isle with Captain Mark was definitely a highlight of our week! He was super knowledgable about the area, the waterways and the creatures that we encountered while on the sandbar. We were not rushed and got there before the bigger tour boats so had it all to ourselves for awhile! We were without children (14 and 11 years old) and my parents. My parents stayed on the boat with Capt. Mark and they enjoyed hearing more about the island and all it offers. We also saw several dolphins. We would definitely book this tour again! Thank you, Capt. Mark!

Our "Vanishing Island Adventure” with Captain Mark was truly unforgettable! He wasn't just a captain; he was an incredible guide, sharing fascinating insights about the marine ecosystem. The Vanishing Island was brimming with life – we found countless sand dollars, vibrant sea stars, and even horseshoe crabs. Captain Mark's informative commentary enhanced every discovery, explaining the unique features and behaviors of each creature. His passion made the entire trip an immersive, educational, and exhilarating experience. Another high was when Captain Mark went out of his way to bring us close to a pod of dolphin. We loved every moment of the trip!
