Visit Us

National wildlife refuges offer us all a chance to unplug from the stresses of daily life and reconnect with our natural surroundings. The refuge offers many opportunities to enjoy wildlife-related recreation. Except for Brown Canyon, refuge trails are open to the public 24 hours a day, seven days a week. Hunting, camping, picnicking and many educational opportunities are scheduled throughout the year. 

All our trails and guided hikes offer great birding opportunities. Many of the back roads in the southeast and northeast grasslands are also good for hiking and backpacking.  

The Brown Canyon Education Center provides many opportunities for learning about the environment and ecology of the region. Take a guided hike or visit with a group and receive on-site instruction by refuge employees.  

Hunting is permitted on approximately 90% of the refuge. Hunting opportunities include mule and white-tailed deer, feral hogs, javelina, coyotes, skunks, white-winged, mourning, and Eurasian collared doves, ducks and geese, coots, jackrabbits and cottontail rabbits. 

The refuge has 83 primitive campsites that are marked with a campsite symbol and number.  There is an occupancy limit of 14 days within a 30-day period. Fires are permitted using dead or downed wood only in established fire rings at designated sites. Campfires may be restricted during periods of high fire danger. Camping is only permitted in designated campsites. No reservations are required, and it is free. 

Horseback riders may ride cross country, on roads, and in washes, except for the Brown Canyon and Arivaca sections. Please avoid creating trails and ruts. Groups using horses must provide their own water and weed-free feed and clean the campsite of horse manure. Groups using four or more horses must possess and carry a refuge permit.
