Puerto Morelos is the perfect town to ride a bike, everything is super close and there are many spots to wander around: Punta Brava (a nice more secluded beach on the south part of town), ride through the road that connects the mangrove with the highway or just move around the area in an eco friendly ride.
We suggest the service of Green Bikes, you can contact directly through Facebook or Whatsapp, they deliver the bike to Aldea Bek and then they come and get it once the rental service is over.
