Rent a bike from one of the local agencies & visit The Wall Of Tears, an imposing lava wall that was constructed by prison inmates back in the 1940s and 1950s. There are plenty of cool spots to stop off at along the trail, from ocean lookouts to secluded beaches and mangrove forests. PS: chances are high you will spot a wandering giant tortoise, relaxing marine iguanas & other Galapagos species. Keep your camera close!
