Quick Guide to Visiting Key Largo

The best time to visit Key Largo is between November and April. Temperatures are comfortable, hovering in the low to mid 80s Fahrenheit, humidity is lower, and hurricane season is firmly behind you. Summer brings heat, humidity, and the possibility of afternoon storms, but rates are lower and crowds thinner if you are on a budget.
Getting around Key Largo is easiest by car. Most attractions are along or just off US Route 1. Some resorts offer bikes for guests, and boat tours depart from several marinas along the island. Parking is generally available at state parks and major attractions.
