We booked two tours (Cloud Forest morning walk and a night walk) with Oscar based on the reviews on trip advisor - which I'd never done before! He was amazing!! We were traveling with 3 kids (4, 6, & 8) and he made the information totally age appropriate and accessible for the kids, but also added in great background, history and information for my husband and I -- and the other guests with us. He was so accommodating and lovely with all of us, I really can't recommend him enough. Thanks Oscar!!
