If memory serves, it was about $35 USD to rent a boat, paddle, skirt, helmet, drytop, drypants, etc. Maybe it was $40? Email Kayak Pucon and they'll fill you in. I think I was paying about $70 for a half day one on one guided, with gear, including a pretty fat tip. Cheaper than a half day skiing at Vail!
They had a ton of boats to choose from, all in good condition and good gear in good condition. (I had an AT2 paddle, IR dry gear, Burn, etc). I really can't say enough about how great Rodrigo and Kayak Pucon were. Definitely a notch above the "other guys" in town.
I recommend hooking up with some people who know the area if you are paddling Pucon. Local knowledge made the Palguin super fun, instead of super tense.
If you are heading down this year, get some beta on levels. I heard that so far Pucon was pretty dry. Might head toward the Futa?
