We went to hang bridges for the morning tour as part of a group. Our guide was donald and he was probably the best guide we had in Costa Rica. In 5 minutes we saw monkeys, birds and some of the venomous snakes around eyelashes. It was evident that his passion "his office" and really got the group involved in the wildlife around us. He taught us how different birds sounded like what and how to find them. He managed to find a dart frog singing toxic. Can't recommend Donna's trip is not too much, it is great!
