We spent a Sunday morning riding in Key Biscayne and decided to cross the bridge to Virginia Key. Since we came by bike we were not charged the $6 / car entrance fee. This fee seems very small if you plan to spend a family day at the beach. We were surprised by how well laid out the whole park area is. It was an easy ride through the main road and some side roads. I remember coming to this beach in the 80's and even though it was quiet and serene, it had fallen into disrepair. At the northern end we found excellent mountain trails maintained by volunteers. At first we were a little hesitant, but were so glad we tried out the "novice" trail that had picture perfect views of downtown Miami and Miami Beach. The volunteer crew even lent us a couple of helmets which we had not brought. There are many areas undergoing restoration which will hopefully restore the native hammocks and beach areas. Will return to try out the biking trails again and also try out the hiking trails.
