The mountainous interior of the island is impressive in terms of its vegetation and small-animal life, making it great for walking. There's perhaps nowhere else in Colombia that you will see so many colorful lizards, iguanas and black crabs scampering through bushes. Beware of a common shrub with spectacular hornlike thorns: ants living inside have a painful bite. Mosquitoes also abound on the island's interior.
Snorkeling & Diving
Snorkeling and diving are the island's two biggest attractions, and you shouldn't miss the opportunity to do either here. The clear water and stunning reef life make this one of the Caribbean's best places for these activities. Diving trips and courses can be arranged with local operators, dive sites tend to be fairly standardized, and there's an ever-increasing number of outfits on the island, which keeps competition healthy.
