Visitor Alert: Arboretum closed until Thursday, Sept. 23

Due to ongoing extreme fire danger in California, the U.S. Forest Service closed all of the state’s national forests in late August. Most of those forests will reopen this week. But those in Southern California, including San Bernardino National Forest, will remain closed until Thursday, Sept. 23. Please check back here for confirmation of the Arboretum’s scheduled reopening next week.

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. (Please see temporary-closure notice above.)

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. (See temporary-closure notice above.)

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.

Fall Native Plant Sale: Postponed

The Fall Native Plant Sale, slated for Saturday, Sept. 4, has been canceled. On Monday, Aug. 30, the U.S. Forest Service announced that all California national forests would be closed through Tuesday, Sept. 17, at least. Please check back here for updates on that official closure and possible rescheduling of our fall native plant sale to Saturday, Oct. 16.

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.

Conservation

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