Several operators do boat trips to see West Indian manatees. The 9,000-acre Swallow Caye Wildlife Sanctuary, established in 2002 in great part due to the efforts of Chocolate Heredia, who sadly passed away in 2013, and his wife Annie Seashore, is home to many of these endangered mammals. It’s just 10 minutes by boat from Caye Caulker. It's illegal in Belize to get into the water with the gentle sea cows, but a few tour operators unfortunately do permit it. Half-day tours typically cost around BZ$75–BZ$100 per person, including the BZ$10 sanctuary admission fee. Some stop at Goff's Caye, which has excellent snorkeling.
Carlos Tours. Carlos Tours, one of the most recommended tour operators on Caye Caulker, runs snorkeling trips with stops at some of the best snorkel spots near Caye Caulker, and also at Hol Chan Marine Reserve and other places, along with manatee-spotting tours. Prices vary according to the destination but range from around BZ$80 to BZ$175 per person. Front St., at Calle del Sol, Caye Caulker, Belize. 226/0058. firstname.lastname@example.org.
Red Mangrove Eco Adventures. Red Mangrove Eco Adventures offers "ecologically sensitive" manatee-watching tours—no swimming with the manatees. It also offers other sea and inland tours. Front St., Caye Caulker, Belize. 226/0669 or 607/1440. www.mangrovebelize.com.
