Summer weather has arrived and Boyce Thompson Arboretum is ready to welcome guests with seasonal pricing, adjusted hours and a changing showcase of desert blooms and wildlife.
The arboretum is at 37615 E. Arboretum Way near the town of Superior.
From June through August, admission for adults is $16 — a savings of $8.95 off the regular price of $24.95. To ensure the comfort and safety of visitors and staff, the arboretum will be open from 6 a.m. to noon throughout the summer and will be closed on Tuesdays during these months, according to a release.
“We have plenty of shaded trails and there are rangers and other staff on site walking around to answer questions,” Kim Gray, Executive director of the arboretum, said in the release. “Whether you’re hiking, birding, or just enjoying the garden’s quiet beauty, early morning is a magical time to experience the desert.”
The arboretum is a destination for birdwatching, with frequent sightings of yellow warblers, vermillion flycatchers, black-throated sparrows, Western tanagers, and many others. Visitors may also encounter butterflies and coatimundis, especially in the cool of the morning.
