Start in San Juan
Puerto Rico is a brilliant choice for a July backpacking holiday, especially if you want a trip that combines lively city days, tropical scenery and plenty of freedom. Start in San Juan, where you can wander between pastel-coloured buildings, listen to music drifting from open doorways and find a different local eatery around almost every corner.
Old San Juan is easy to explore on foot and makes a memorable first stop. Visit the impressive forts of Castillo San Felipe del Morro and Castillo San Cristóbal, then pause in a shady square with a cold drink. July is warm and humid, so take things at an easy pace, carry water and plan some time indoors during the hottest part of the afternoon.
