Captain Mark was very informative along our tour to the sandbar. He gave us history of the area, shared with us about the sea life, and birds that we saw along the way. It was a very enjoyable, relaxing trip. Once at the sandbar he helped us find sand dollars and identify shells, jelly fish, and crabs. My family and I had a fantastic time, and we will do this again.

Great tour! Absolutely beautiful area. Captain Mark was full of great information. Found some great shells and had a breathtaking boat ride. The experience was enjoyed by the whole family! Definitely want to do this again.

At the end of October 2023, our family took the Vanishing Isle Tour and the Sunset Dolphin Tour, on two different days. They were both spectacular, and Captain Mark was wonderful. The entire group loved both tours, but all were especially impressed with the Vanishing Isle Tour. If either or both interest you, I would highly recommend them. Captain Mark was incredibly knowledgable and made the entire process a delight. We would absolutely do both tours again, if we are in the area.

Captain Mark’s tour was the best part of our trip to Hilton Head. My adult children and grandkids were constantly squealing with excitement. We learned a lot of facts about the ocean on our way to see dolphins. Being on a tour with six people made it an experience we shared as a family. We went to our own corner of the vanishing island and didn’t have to share our experience with all the other people across the way. The two older grandkids love science and had a lot of questions which he answered. He showed the kids how to look for starfish and they each found a whole sand dollar they could take home. When it was time to go back my granddaughter told him how she reads every book she can about dolphins. He then took us to see if we could find them strand feeding. When we got back to shore the kids said it was the very best part of vacation and could we please go again the next day. Had it not been a hurricane today if he had availability I would have scheduled another trip. Today he texted us pictures and a video he took of us and thanked us for choosing his tour. The kids can’t wait to go home and tell their friends about their trip to the vanishing island! Book it now!!

The kids asked if we could do that every day of vacation..that says it all! Captain Mark told us all about what we were seeing and then patiently answered the grandkids questions. He made sure we saw lots of dolphins and when he heard our granddaughter loves to read and study about dolphins he took us to try to observe strand feeding if they were doing it. On the island he helped the kids learn about the creatures they were seeing and helped them each find a sand dollar they could bring home. This tour is limited to six people and we were taken to a separate area of the island from the boats bringing many more people. He is responsive to messages and wants each person to have a good experience. If we weren’t having a hurricane today and he had an opening for a group, I would take the grandkids again today. They can’t wait to get back to school to tell their friends all about it and show them the pictures Captain Mark sent them.

I was lucky enough to find Captain Mark via a recommendation, and the trip totally exceeded our expectations. Our party (2 adults, 2 children) took the private tour to the Vanishing Mile Island. We saw sand dollars, sea stars, crabs, shells, and lots of Dolphins accompanying us to the island! Captain Mark was very knowledgeable and taught us about the eco system around HHI. Returning to the dock, Captain Mark took us to some tidal mud flats first, where we saw dolphins strand feeding, amazing experience. We highly recommend Capt. Mark.

A trip with many highlights had Mark’s tour near or at the top! He made us feel right at home on his boat and offered his extensive knowledge freely. We learned a lot and had even more fun. Highly recommended! Thanks, Mark!

Mark was very knowledgeable and polite. His boat was comfortable and clean. We had an amazing trip! We even got to see some dolphins on the way to the sandbar island. A+ trip

Our family took the private tour with Captain Mark. He took us to the Vanishing Mile Isle to look for sea creatures and shells. We found both! We saw sand dollars, sea stars, crabs, rays and a big horseshoe crab! Captain Mark was very knowledgeable and taught us about the eco system are HHI. We got to the sandbar early so we got to explore before EVERYONE else showed up. On our way back we saw several dolphins. They hung around our boat so we could watch them. . Our family covers many age groups and all of us enjoyed the tour very much. We highly recommend Capt. Mark.

Excellent! Our group had a great time on the vanishing mile island trip. It was fun to walk around in the middle of the sound and find shells, sand dollars, and star fish. We had three adults and three kids (6,7 and 10) and everyone had a good time. Definitely recommend

Great captain, very knowledgeable. It was great seeing dolphins and crabs. Vanishing isle was an amazing time and we had so much fun!

Cross Island cruises was amazing from start to finish. They were very quick in responding to my questions initially at booking and communicated prior to ensure we knew where to meet. The tour itself did not disappoint! We were able to see so many dolphins including babies and they were so close. Mark even had a camera and sent us pictures so we could enjoy the experience and not have to worry about capturing the moment. We saw so many new and different creatures on vanishing island and Mark was so knowledgeable in explaining everything we found. He also made a special stop so we could explore another area my son loved! Highly recommend this tour and this company!

Wish we could have stayed longer on the island, but mother nature wouldn't allow. My family really enjoyed out time seeing the sea creatures that were all over this sand bar. Water kept shifting so one area not exposed, then became exposed. Bring a little bag to keep your treasures in that you find. Very friendly and enough room for many people to explore and not be crowded. Was a highlight of our trip.

Hands down, BEST part of our trip to HHI! We had to change our itinerary a bit due to unexpected high winds, But Captain Mark gave us an amazing tour! His knowledge of nature is extraordinary. We've been to the Island many times and thought we knew it well, but seeing it through Captain Mark's eyes unveiled a whole new world to us. Cannot possibly rave enough about this experience. Stop reading reviews and proceed to cart on this one. You'll love it!

Captain Mark was amazing as always!! Tide was up, but he took us around the island & we were able to see a live crab & my daughter held the crab!! Best experience & would highly recommend!!

This was an excellent tour!!! Our 3 kids loved seeing the dolphins and collecting sea shells. We saw countless dolphins and got to see different underwater species up close. Plenty of starfish. Captain Mark was great with the kids and knew a lot about the area and different species. When we come back to Hilton Head we will be booking this tour again.

I don’t normally take time to write reviews but our tour with Mark was amazing. My husband and I took my nephew and his girlfriend (age 19) on vacation. We did so many things during the week but this tour was BY FAR the winner of what everyone enjoyed most during the week! We saw dolphins, we experienced the vanishing beach, we saw all kinds of star fish, jelly fish, sand dollars, etc, and learned so much about the island and the waters around it. It was an all around great experience and one that we will remember forever. Thanks Mark for such a memorable experience!

The Invisible Island Tour was fantastic. This was a must do while in Hilton Head. Captain Mark was a steward of the sea. An experienced guide. The trip was non-stop fun!

We were lucky enough to find Captain Mark for the Vanishing Island Tour and we are so glad we did! Our family, 5 adults and a 4 year old, thoroughly enjoyed our trip to the island both finding dolphins, rays, pelicans, ospreys, horseshoe crabs, starfish and various other sealife. Any question we asked Capt. Mark was met with a knowledgeable answer and sometimes humor. My husband even enjoyed discussing various boats used on the island with Mark as we made our way back to the dock. We highly recommend Cross Island Cruises and will definitely be visiting again. Thank you!

Mark is an excellent captain and very knowledgeable about the wildlife and marine life in the area. He showed us many many dolphins and many many star fish and cannon ball jellyfish. We even got to see a few sand dollars. He narrated the tour and gave lots of highlights. This was very relaxing for us to not be with a big tour group. Highly recommend
