The beautiful '''Reserva Ecologica Cayambe-Coca''' presents miles of lakes and trails in a preserved and secluded setting. Access/camping/fishing fees were $5 in 2007. This reserve receives support from The Nature Conservancy, USAID, Parks in Peril and Rumicocha Ecological Foundation. The reserve is located high in the Andes around 13,000 feet so it receives quite a bit of rain. Access points are located past Termas de Papallacta as well as near the summit on the Via Interoceanica (as you reach the summit, look for a cement hut 1/4 mile off the road to the north).
There are a few hosteria's (small family run hotels) that are inexpensive. A few of them are located along the road from Quito to Papallacta. Ask the bus driver to stop in Papallacta and you will easily find one if you continue walking along the road.
You can also stay at '''Termas de Papallacta Hot Springs Resort''' which is more luxurious and more expensive.
