America 250: Blue Flower Moonrise over the Desert (Registration Required, Limit 25 )
May 31 @ 7:30 pm - 10:00 pm
Celebrate two and a half centuries of the American spirit (America 250) under the glow of the Blue Flower Moon. This 2-mile hike is rated easy and features an elevation gain of under 200 feet. We start with a nature walk on the Tortoise trail, stopping to learn about the Sonoran Desert along the way. Then, we climb the short Hilltop trail (approximately 0.5 miles) for a spectacular view of the moon rising over the Mazatzal Mountains. Please wear sturdy, closed-toe shoes, bring plenty of water, and a handheld flashlight (please refrain from using headlamps). This program is weather-dependent. Please allow 15 minutes upon park arrival to use the self-pay station and reach the trailhead, which is a few miles past the park entry.
MEETING LOCATION: Trailhead Staging Area by the restroom building
