What are people saying about Key West

Melissa_H, May 2026

Great experience for a first time snorkeler.

The captain and her crew were very nice. Answered questions and visited with guests. They gave a brief overview of what to do when you got in the water, but if someone had additional questions, they answered those as well.The vessel and the equipment were clean. If we come back to the area, we will likely do this again. I also felt the price was fair.

Don't pick any other company but Danger Charters

Relaxing, no rush, phenomenal crew, extremely enjoyable. Perfect for singles and couples. Other places like Sunset Co. or Fury is so commercial, robotic, everything must be done their way,otherwise you are out.This company is different, noone is loud, crew is polite, sweet and funny, they leave you alone to relax. Anna, the captain, Kayla and Trevor are so down to earth. No rush to do anything, we were sailing for 5 hours, awesome!

Key West Sailing & Snorkeling: A Reef Adventure

Tania_B, May 2026

Well organized!! LONGER (actual) SNORKELING time!!

The captain and first mate were friendly, courteous, informative. Prior to sailing, thorough safety education /instructions were provided. The captain selected an optimal area with consideration to weather/wind conditions. He was knowledgeable of region for optimizing viewing of the varied marine-life. The boat and snorkeling gear were clean, well maintained. We selected “Fish Monster,” due to advertised as having longer actual snorkeling time than the majority of other snorkeling trips we were considering. This is a well organized excursion. The captain, first mate and details previously mentioned provided our group an overall great experience. Highly recommend!!

Our family really enjoyed this snorkel adventure! The crew were knowledgable and informative, putting safety first but making sure we all had a great time. We got very lucky with the weather and saw the most beautiful sunset on the way back from the dive sites.

It was a small...

It was a small personalized experience. Captain Mary and first mate Frankie did everything possible to make the trip one to remember. Great food, drink, and experience. Frankie even gave us a great lesson on the Keys and the history. We snorkeled and took kayaks around and through the mangroves.

Fantastic snorkeling and dolphin spotting too!

Beautiful weather, clear views and two great reefs! The crew was super friendly and so much fun. The capacity of the boat was perfect, plenty of space to spread out and be comfortable. Highly recommend! Top it off, the Captain spotted a dolphin pod and slowed the boat to be sure everyone got a view!

Melissa_C, Apr 2026

Great experience!

Fun day! We enjoyed the 45 minute ride to the reef, boat was clean and comfortable, crew was friendly, and there was a bathroom on board and plenty of water available. Snorkeling was great…beautiful reef, saw lots of fish, safety information and guidance from the crew was super helpful. Note…snorkeling was off the boat in open ocean, so maybe a bit intimidating for first timers or young kids? That said, the crew did a great job of providing help, ideas and modifications to accommodate various swimming levels and snorkeling experiences. Music and fruity adult drinks were also a fun touch! Would definitely recommend!

Amazing morning snorkelling in Key West!

Really well organized, an excellent experience! Fantastic and personable crew. Instructions and guidance were clear. Equipment was clean and the snorkel site had many colourful fish swimming around coral reefs. Captain slowed and stopped the boat on the way back to allow us to see dolphins.

Kim_S, Feb 2026

Misrepresented Breakfast

Nice 3 hours at sea. Boat clean staff friendly. However , it was advertised as Offering “Gormet” breakfast which it certainly was NOT. Breakfast was dry croissants (no butter or jelly etc) and sliced cantaloupe. Breakfast should be described at Continental at best. Overall good experience.

Amy_B, Jan 2026

Great excursion from Key West

My husband and I did this trip on Christmas Eve and had a wonderful time. We weren't sure we would really see dolphins, but we did! Our captain diligently drove the boat around until we found a group or two in the shallows. We then went to a different area to snorkel for a bit; there were some fish but not a ton of sea life (I didn't mind, it was fun just being in the water). They provided drinks after swimming and the vibe was very laid-back and friendly. We had a great time and would recommend this trip to others!
