Is Cuesta del Viento good for beginners?
Kiteforum rates it from beginner to expert. The reservoir is shallow, with flat water and chop. Beginners take windsurf lessons in the lighter morning wind, and the stronger afternoons belong to riders who can handle gusts.
Tiempo de San Juan notes that the wind usually pushes riders back towards the shore. That helps if you break something or get tired. The same report lists wing foil among the sports on the reservoir, and the tourism board adds kayak.
What should you watch out for?
The Zonda is the main warning. It comes only now and then, and Tiempo de San Juan calls it technical, for experienced riders only. If it blows, judge the conditions before you rig.
Kiteforum describes the beach as rocky. Plan your launch and landing with that in mind, especially as a kitesurf beginner.
