My adult son and I took a full day pedal and paddle tour near and on Lake Arenal led by Santos. We went mountain biking in the morning - the route was incredibly beautiful with 2 water crossings and very few cars. Santos is the best combination of friendly, kind, funny, and knowledgeable. The company provided a delicious lunch of a burrito bar with ample portions. In the afternoon we took a boat across Arenal to get out of the heavy wind and kayaked in a gorgeous cove around the peninsula and saw Amazon and Ringed Kingfishers, Osprey, Long-tailed Tyrant, Motmots and more. Santos took great care of us to ensure a positive kayak experience to get us out of the wind and experience the peace and wildlife. To end a perfect day, he took us to see a Great Potoo! I could not possibly say enough wonderful things about Santos.
