5.00Really fun experience. Very reasonable price, easy access on and off the boat. The crew provides a nice wet suit to wear along with waters and nice personal tubs to put our stuff in. Feel free to bring your own snacks, drinks, and pack a sweater or long sleeve shirt / flannel

Starfish, an evening of snorkeling and a million bright lights.

5.00Being with the starfish in their natural environment was fun and educational. The bioluminescence swim was something you have to experience to appreciate. The crew was awesome. They took pictures of us and airdropped them after. Also called taxis if we need a ride back to the hotel. Snorkeling at night was so cool. Every move in the water results in an explosion of a million lights.

5.00An experience we will forever cherish. Felt like we were swimming thru blue stars. The crew was so friendly and helpful. Sunset and double rainbow were a bonus.

1.00The starfish point was a big disappointment. It’s not even close to the pictures that they showed on their ad. They docked the boat to a tiny shore where there’s so many people camping. We saw about 4 starfish in 30 mins in a crowded beach. It was a waste of time and money.

5.00A very unique experience! Our guides were knowledgeable and courteous. We were fortunate that the skies were clear on our return and we got to observe many stars.
Don't miss it.

5.00Aaron and Peppe were so wonderful! This experience was SO COOL!!! They were informative, funny, warm, and well prepared. We really appreciated the bins on the boat to keep items dry. Being on the boat and visiting starfish bay during the quiet sunset added to the magic. Aaron was also a great photographer and made sure we got the best sunset background haha. The rash guards used were also very stretchy and they had options for all body types and sizes. The best part was swimming under the boat and seeing the bioluminescence really glow! There was plenty of time at both locations and we would highly recommend!
