    With an outstanding reputation built on consistently excellent experiences, this operator delivers memorable water adventures in the Florida Keys. The crew members—including Matt, Mike, Jason, Jody, Eric, and Joel—earn enthusiastic praise in nearly every review for being friendly, professional, and genuinely making the difference between a good day and a great one. Their knowledge and warm hospitality stand out as the defining characteristic of these trips. The snorkeling at Sombrero Reef impresses visitors with colorful fish, nurse sharks, and rays, while the sandbar stops and sunset cruises round out popular combo tours. First-time snorkelers consistently report feeling comfortable and well-guided throughout their adventures. The boats and equipment get high marks for cleanliness and quality. Guests frequently mention planning return visits or making these trips an annual tradition, which speaks volumes about the experience you can expect.

    We have been on many snorkel excursions throughout the keys, but Sole has been our favorite! The smaller group size and boat was lovely compared to some larger charters. The Sombrero reef and island tour was incredible. The private island has mangroves and a lovely sandbar that absolutely made the experience top notch. It felt much more personal. We will definitely be back! Trying to remember the crew members names…Art and drew (they said it several times but I’m terrible with names lol).
