I love the bike rides, plus stop at museums, take photos, eat at a restaurant with views. Do bring bikes if you can, plus renting is a breeze at the shop at the top of the island. Picture endless ocean panoramas, the Southernmost Point, untouched rural countryside, coconut trees, and native flora and fauna. The A1A route is bursting with destinations and landscapes that beg you off of your bike.
I tell everyone to rent bikes rather than doing the trolley tours, as the bicycle are perfect all day or at night, as they have lights too!
Fun it is. The good news is for island trips is biking is the way to go. All locals and visitors use bicycle for exploring and experiencing authentic Florida Keys pleasures. Call ahead, plus look at the bike rental selection to reserve your ride. The mile marker four bike shop is fantastic.
