On Saturdays starting this week, the Arizona-Sonora Desert Museum, 2021 N. Kinney Road, will stay open till 10 p.m. At night, “bats turn into insect-seeking missiles, and scorpions glow under black lights,” the museum promises.
As the heat ratchets up, it’s a cooler way to visit the world-renowned attraction, which is part zoo, part botanical garden, part aquarium. Each Saturday has a different theme, starting with World Oceans Night, a collaboration with California’s Monterey Bay Aquarium. Admission rates top out at $19.50 (DesertMuseum.org).
