St Vincent and the Grenadines' volcanic features and coral reefs make their underwater topography ideal for diving. Breathtaking walls and spectacular drop-offs combined with large reefs and shallow coral gardens provide first-class day and night dives. Top sites include those around the coastlines of the larger islands, or the spectacular coral reefs of the Tobago Cays, reached on daytrips.

A large network of hiking trails weaves through St Vincent's rugged, mountainous interior; though you can follow them on your own, you'll be better off hiring a guide. The other islands are so small that walking is the easiest way to get around, but be wary of walking in the midday sun and take plenty of water.
