We had a great time in Puerto Rico for our second anniversary. My husband and I decided to do the 2 hour Rainforest ATV tour. The tour guides were very friendly and experienced. We stopped at a river to swim but I just put my feet in the water while my husband splashed around. We also wrote our names on the rocks with the natural "chalk". I rode on the back with my husband and we both enjoyed when you got to rush through the mud puddles, you do get DIRTY!!! but it is loads of fun. Indeed the best part of our trip!
