Alvaro, Manuel, and Cesear are excellent surf instructors and friendly, funny guys. They took great care of us and taught us in a safe and fun manner. We were riding waves right away.
Playa Grande is a bit of a walk from Montezuma so have comfortable sandles or watershoes. You should bring plenty of water as it gets super hot, but the boys will supply you with fruit and they may even climb a tree and grab you a fresh coconut so you can drink from it.
You should definitely have the guys arrange a trip to Cabo Blanco for surfing and a beautiful sunset. Our day there was the best day of the trip as the waves were very big and VERY fun and the sunset is perhaps on of the most beautiful on earth.
The guys at Young Vision are fantastic. Be sure to surf with them when you visit Montezuma!
