Directions & Parking

Visitor Alert: Pandemic Protocols and Parking Passes

The U.S. Forest Service has recently reopened restrooms at the Arboretum and resumed trash collection. Because of the ongoing pandemic, we strongly advise visitors to wear face masks and observe social distancing. An Adventure Pass (or other valid pass) must be displayed when you park in our lot. We look forward to your next visit!

Fall Native Plant Sale

Our regular fall native plant sale, which had been scheduled for Saturday, Sept. 5 (Labor Day weekend), will not be held this year due to the ongoing pandemic. But a smaller-scale event may be staged in late September or sometime in October. Please watch for possible details here.

Explore the Forest

This family- and dog-friendly trail is nearly one mile long. Descending and then rising gently, it’s an easy hike with numbered signposts along the way. An information-rich trail guide, keyed to those numeric posts, makes your hike even more interesting and educational.

The Arboretum’s gardens display a wide variety of flowers, shrubs and other plants. Largely native to the San Bernardino Mountains, many of them are identified by easy-to-read signs. The nearby Information Booth offers print and visual aids to help you learn even more!

Expertly guided tours are available on request. They’re intended especially for visiting groups such as schoolchildren, Boy and Girl Scouts, gardening clubs and birdwatchers. For details: info@hparboretum.com.

The San Bernardino National Forest encompasses more than 800,000 acres and seven official wilderness areas. There’s so much to see,  experience and learn here. With education and inspiration in mind, Heaps Peak Arboretum is a great place to visit. It’s a forest treasure that draws guests from across the region, other states and even countries overseas. 

Through habitat restoration, trail maintenance and other efforts, we’re working to protect and conserve our area’s expanse of the National Forest.
