Cancun is an unusual city in that it is surrounded by water but is not an island. The resorts are on a narrow strip of land that leads up to Cancun. Every direction you look there is water. The Caribbean is a bright blue color with strips of green. The beaches are a white sand that always feels cool to your feet.
