Cerro Chato is yet another beautiful crater lake found in Costa Rica. It blew its top an estimated 3500 years ago. Today it contains a beautiful emerald green lake surrounded by lush rainforest. Marvin, a Tico friend, had the strength to haul a 40 pound inflatable kayak up the steep trail for two hours. He gave me the easy job of doing the reverse trip. My dogs, Puppy, Geisha and Ziggy, were exhausted from the climb, burden free!! This is probably the fifth time my dogs have kayaked in a crater lake.
