Snorkeling and Scuba diving.
Belize's barrier reef has been named one of the Seven Underwater Wonders of the World. While snorkeling or diving in Belize there are many places you can go, such as ayes, the atolls, various spots on the reef and the mainland. You can see clearly 100 feet or more of water. The water temperature stays close to 80 degrees Fahrenheit all year long and the barrier reef makes for calm water almost year round.
Wind surfing.
The Cayes have flat and quiet waters that are created by the protecting reef. The constant onshore/side shore winds provide a good location for beginners to have a first lesson. Winds can get up to 10 miles her hour. The water below is so clear that you can see fish and stingrays and it is not unusual to see dolphins as you sail. For the more experienced surfer, there are several wave sites and of course access to the swells on the outer reef.
Canoeing and Kayaking.
In a place like Belize canoeing and kayaking are very common with waters like these. Whether inland on one of the many river systems, in and around a cave or out on the open sea near the reef and the cayes, you will have a chance to witness the unspoiled nature of Belize from a different point of view.
Caving.
Belize has unbelievable cave formations. There are alot of caves in Belize filled with Limestone. Although most caves have not been thoroughly explored yet and because of the isolation of them you will find natural splendors and archaeological significance such as ancient Mayan Pottery and abundant species of animals such as blind white crayfish and numerous arachnids. Rio Frió, St. Herman's and Barton Creek Cave are some of the caves that are accessible and inviting to be explored. Many caves are closed to public exploration because most have archaeological significance.
