Do Buenos Aires National Wildlife Refuge
Managed by the US Fish and Wildlife Service, this was established in 1986 for the reintroduction of masked bobwhite quail and pronghorn antelope. A number of other mammals and avian species are well-established here, making this an excellent place for watching birds and wildlife. Guided tours are offered by the Friends of Buenos Aires NWR (+1 317-354-7352, fobanwr@gmail.com).
Do Baboquivari Peak Wilderness
This remote wilderness area is on the eastern side of the Baboquivari Mountain Range 50 mi (80 km) southwest of Tucson, and is administered by the Bureau of Land Management. It is notable for the spectacular Baboquivari Peak which is sacred to the Tohono O’odham people, and is clearly visible from nearby Kitt Peak National Observatory (see listing above). The area offers good opportunities for hiking and photography. The peak can be scaled but requires technical climbing ability; a good trail description can be found here. There is an alternate western climbing route, although to use it prior permission must be obtained from the Tohono O'odham Nation.
