Our tour was set up by Desafio Monteverde Adventure tours. They did a wonderful job. We visited Costa Rica 9/12/2010 thru 9/19/2010 which is their rainy season and their "low" season for tourists. We stayed at the Montana Monteverde and I would recommend that hotel to anyone. The rooms are spacious and clean and the hotel restaurany is excellent. I highly recommend the cloud forest walk and the zip lines (Desafio arranged our zip line experience with Selvatura). I am 67 and my wife is 58 and we both had fun on the zip lines. I would recommend you do them as a morning activity during rainy season. We did them in the afternoon and had a driving rain storm while we were zipping. Overall I was extremely pleased with the area and the arrangements made by Desafio.
