Lodging
Inside the park there are refugios for climbers, but most lodging is outside the park limits, and some visitors come on day trips out from Quito. All inclusive lodging is available at several quite luxurious haciendas near the park limits, for example Hacienda el Porvenir, while cheaper lodging is available in the small towns close to the park. There is a working hacienda on the east side of the park that offers campsites firepit, running water, bathroom as well as individual rooms. See www.haciendayanahurco.com.
Tambopaxi
The only lodging available within the park itself, this lodge is popular with climbers and also provides meals. Access to the Refugio on the way to the summit is easy from here.
