One of the most attractive thing about San Andres is the beauty of its underwater life conveniently and surprisingly close to the shore. San Andres has over 40 diving spots many of them close enough from the shore that even novice swimmer should have no problem getting to them. The really famous spots even have stairs so you don't mess up your feet when getting in and out of the water, these are:
- Sunken Ship AKA Blue Diamond (200 meter swim from the shore) Right in front of a hotel named "Playa Tranquilo"
- Nirvana (200 meter swim from the shore)
- El faro (The light house)
