Tohono Chul Gardens, surrounded by suburban development, preserves 49 acres of plants native to the Sonoran or Chihuahuan Deserts. The gardens support thirty-eight species of birds and provide a stopover for 57 migrant species. Trails wind through themed gardens and loop around groups of saguaros and other native cacti. A small museum displays the work of local artists. The greenhouse has a good selection of native plants for sale.
A very small portion of the trail near the garden entrance is paved and accessible. The rest of the trails, except of the South Loop Trail which has a washed out section and a steep hill, are hard packed sand with small stones and are mostly accessible although wheelchair users may need assistance. The Saguaro Discovery Trail can be accessed by the fairly level, southern most section of the South Loop Trail. The Desert View Trail has hills and loose sand so backtracking and assistance may be necessary. The museum and greenhouse are accessible.
