Stargazing in Nogales is surprisingly rewarding if you know exactly where to set up your tripod. While enthusiasts often gather at Tumacacori National Park for its accessibility, scientific audits conducted by the National Park Service at Rincon Peak provide the most accurate reading of the regional sky quality, measuring at a Bortle 4.0. The transition between the urban infrastructure of Nogales and the more rural stretches of AZ creates several ‘dark sky’ corridors.
The Best Times for Stargazing in Nogales

Expert Tips for Nogales Observers
When visiting Tumacacori National Park, remember to check if the gates close at sunset or if a night-use permit is required. A medium-aperture telescope is ideal for resolving the rings of Saturn and bright star clusters here. Local enthusiasts often frequent this spot, making it a great place to meet experienced observers. Regardless of your gear, allow 30 minutes for your eyes to fully dark-adapt.
