Nam Pha Pa Yai is such a gem of a climbing camp! It is just north of Bangkok and is accessible by car or train. Being so close to the city, it is surprisingly quiet and intimate. There is no wifi and very little cell reception. The rock is solid and the routes are long and varied. With home cooked dinners and less than 10 people a night, it is a beautiful place to lay low and just climb. Did I mention you zipline to the wall? Also that you can stay in a tree house if you book early enough? I loved it and would love to return when the weather is cooler.
