Visitor Alert: Fire danger diminished but still present

Cooler temperatures and higher humidity have moderated the threat of fire in the San Bernardino National Forest. But on windy days in particular, that threat is elevated once again.  It will remain, even at reduced levels, until snow falls and then stays on the ground. Until then, please continue to be vigilant and honor all U.S. Forest Service fire-related rules. Thank you!

Hours & Calendar

Because of the wildlife in and around the Arboretum, it's potentially unsafe to visit the site and especially to hike the Sequoia Trail after dark. During daylight hours, that's not an issue.

With schools back in session, the booth is now open on weekends only--from 11 a.m. to 3 p.m. We accept cash and cards, but please note that the minimum credit or debit purchase is $10.

Adventure Passes

An Adventure Pass or other valid pass (such as America the Beautiful) is required to park in the Arboretum’s lot–whether or not the Information Booth is open. As always, entrance to the Arboretum itself is free.

Spring Native Plant Sale: May 28, 2022

The Spring Native Plant Sale is slated for Saturday, May 28, 2022 (Memorial Day weekend), beginning at 9 a.m. Please visit our site again closer to the actual event date to check on any schedule changes. The plant list below, from the Oct. 16 sale, is for your information.

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.
