East of Belize City on the southwest side of Turneffe Atoll, the snorkeling at Blue Creek is known for its octopus, eels and lobster. The waters off Blue Creek range from 20 to 35 feet deep. This is a popular overnight dive spot with the live-aboard charter dive boats. While snorkeling Blue Creek at Turneffe Atoll, you may encounter groups of spotted eagle rays and barracude around the reef floor habitat including tube sponges, sea fans and feathers.
The Turneffe Atoll snorkeling is located 25 miles southeast of Belize City. Unless you are staying at Turneffe Atoll, you'll need a boat charter to reach it. There are a few dive charters regularly heading out to Turneffe Atoll. At best, most operate once a week, depending upon weather and the minimum required number of reservations. You'll want to check with each company to verify that they are actually going to snorkeling sites and not wall scuba dive sites. If time permits, you may want to consider Turneffe Atoll as a good central base for also exploring other atolls in the region.
To reach the snorkeling in Belize by air, fly into Belize City International Airport (BZE) which is located west of Belize City. Since there are few hotels near the airport and the airport is pretty far from the sketchy Belize City, you will want to arrive as early in the day as possible to meet your connection. There are two small inter-island airlines that serve many other destinations off-shore of Belize. Note, even if you reserve a specific inter-island flight at a specific time, only after you check-in with the inter-island carrier are you really assigned to an actual flight at an actual time. While there is a ferry service from downtown Belize City to some islands, there are only informal taxis (in personally owned vehicles) from the airport along slow roads thru run-down neighborhoods to the ferry dock, which is located in a very sketchy area. Hence, the ferry service does not tend to be a very popular option with tourists. When you are departing from Belize, the departure tax is included in the airline ticket, but make sure to verify.
Overall, Blue Creek is the 26th most popular snorkel dive spot of all 33 snorkeling dives in Belize.
