Looking for a fun, cheap, activity on Isla Colon? Rent some bikes and explore for the day! A plethora of rentals are scattered around Bocas Town and you'll have the choice of renting per hour or per day. Prices range greatly, but the best deal we found was $5/day or $7/24 hours (located at a small unnamed booth in the fork in the road around the corner from the fire station.)
Though the island is a decent size, the limited number of roads makes it easy to navigate. You have three basic options for biking on Isla Colon. Ranging from easiest to most difficult they are:
Cruise the roads of Bocas town. You can spend as short or as long as you want circling the busiest part of the island, but watch out for all of the vendors and pedestrians in the street.
Heading north from town you'll pass some neat little eateries (and Bocas Brewery!) on the beach road. You'll eventually come to a marked fork in the road where you'll have two options.
Head to Playa Bluff. This mostly flat road will end shortly before playa bluff, but thanks to 4-wheel drive traffic, the sand on the beach is packed tight enough to still be a decent ride. Stop at Paki Point for lunch and lounging- it's one of my favorite chill out spots on the island.
Take the longer trip to the beaches of Boca del Drago. This 15km route definitely requires some leg muscles to get over the fairly constant hills, so if you're in the hunt for a bigger challenge, give it a go!
No matter what route you choose, I'm sure you'll have a great time biking on Isla Colon!
