Adventures in the Cayman Islands!

Welcome to the Cayman Islands! If you've heard about the fantastic stingray city excursions in Grand Cayman, then you have Captain Marvin to thank for that. Our captain was a founding father of stingray excursions in Grand Cayman!

Whether it's snorkeling around the coral heads and reefs, swimming with stingrays, or enjoying the wonder of sea stars at Starfish Point and the other-worldly night-time bioluminescence tour, you will discover amazing things in our waters!

If you are looking for the best fishing charters in the Cayman Islands, we have you covered. Our experienced captains will take you deep sea fishing for marlin, tuna, or wahoo. Grand Cayman is also an excellent place for reef fishing (yellowtail and red snapper, grunts, triggerfish, jacks), and our knowledgeable guides know all the best places to go. Come with us to explore all that Grand Cayman has to offer. Adventure calls and we must go!

Two-Stop Stingray/Snorkel Tours

Our two-stop stingray/snorkel tour lasts about two hours and 30 minutes, slightly shorter than our three-stop stingray/snorkel tour. The two-stop trip goes to the Stingray City sandbar plus one snorkel stop, either the Barrier Reef or the Coral Gardens. Our captain will decide when he gets out to the stingray/snorkel areas which snorkel stop to use, based on wind, wave, and tide conditions, as well as on the number of people at each of the two areas. We always try to go to the less populated of the two stops.

We strongly recommend that you bring flotation devices for children under age 3, as our snorkel gear is for ages 3 and over.

Beach Lunch Stingray/Snorkel Tours

Capt. Marvin's Beach Lunch Stingray/Snorkel Tour is the best of the best! It includes two snorkel stops (one of which will be a conch dive during conch season, Nov. 1st through April 30th), the Stingray City sandbar for interaction with the stingrays, and a fresh seafood lunch on the beach across the North Sound (near Kaibo/Rumpoint).

Our crew will dive for conch in season and you are welcome to help them. They will even clean up some shells so each family unit who wishes can take one back home with them (supply limited). The rest of the year, you will have extra snorkeling (or Starfish) stop instead of the conch dive.

Words from our customers


Grand Cayman, Cayman Islands

Grand Cayman and the most beautiful Seven Mile Beach

Three islands form the Cayman Islands: Grand Cayman, and the sister islands of Cayman Brac and Little Cayman. While not quite seven miles long, the beach is still popular for its beautiful white sand and clear blue water teeming with marine life. A barrier reef at the northern edge of the North Sound at Grand Cayman is an excellent spot for a snorkel trip.

For such a small island, it is surprising to know that Cayman is home to over 100 different nationalities. The three islands are situated at the center of the western Caribbean Sea, surrounded by Cuba, Jamaica, Mexico, and Central America. As one would expect, seafood is featured at most restaurants. You'll also find spicy dishes from Jamaica, like jerk chicken. The traditional dessert is cassava or "heavy" cake, made with grated cassava and coconut milk. The delicious cake is seasoned with vanilla, nutmeg, and cinnamon.

Yes, however, pregnant women are not allowed to do any of the dolphin tours.

It is recommended that you know how to swim if you intend to do any snorkeling. We have a lifebuoy that you may use to hang on to during the snorkel stops so you can see the fish and coral if you are not comfortable swimming.

The water at the Stingray City sandbar is 3-4 feet deep. We anchor the boat nearby in about 5-6 feet of water so we don't run it aground, and you then make your way over to the shallower area where you will stand in the sand while the stingrays swim around you. The snorkel stops are in 8-10 feet of water.

We recommend that you wear your swimsuit under a cover-up or shorts/t-shirt as the only place to change clothes at Stingray City is in the head on the boat.

We strongly recommend that you know how to swim before taking a snorkeling trip, but our crew are experienced at teaching beginners how to snorkel. Just ask them when you get to the boat.

If you book online, you will be charged upon completion of your reservation. If you book by phone or in person, you will be charged when you check in with us on the day of your tour. However, we will need a credit card to hold your reservation either way.

If your cruise ship cannot stop here on its scheduled day, or arrives too late for you to take our tour, you will not be charged. If you need to cancel your reservation for personal reasons, please do so at least 24 hours in advance to avoid being charged. If your ship arrives on time and you do not show up for your tour, you will be charged. If the weather is such that our captain cancels our boat trip, you will not be charged, but we do not cancel for rain only.

If your ship arrives too late for your tour with us, or is not able to stop at all, you will not be charged. However, in most cases, we will have been made aware in advance that your ship will be arriving late, and we will do our best to make adjustments to the timing so that you can still take your tour with us. Please check in at our office in the Waterfront Centre as soon as you are able to get off the ship to see what we have been able to arrange for you. If you have booked through a tour agency and have paid them in advance, you will need to deal with them directly to receive a refund.
