Visitor Alert: New guidance on COVID-19 rules

The Centers for Disease Control (CDC) has just issued a new set of pandemic-focused guidelines as Americans in increasing numbers are vaccinated and the threat of COVID-19 diminishes. According to the CDC, fully vaccinated individuals are no longer required to wear a mask outdoors and also in most indoor settings. If you’ve been vaccinated, you can come to the Arboretum, walk its trails, enjoy its picnic area and simply relax in this beautiful setting without a mask. Of course, you may choose to wear a mask as an ongoing precaution.

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.

Beginning in mid-May and extending through summer, the Information Booth will be open 11 a.m. to 3 p.m. Tuesday through Sunday.
Events Calendar

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.

Next Native Plant Sale: Saturday, May 29

Our Spring Native Plant Sale will be conducted on the Saturday of Memorial Day weekend.  Although the threat of COVID-19 has diminished and the CDC has recently issued new guideless, we strongly suggest that for this “crowd intensive” event, everyone should wear a mask and, as much as possible, honor social distancing. The sale begins promptly at 9 a.m. and lasts until about noon. To secure an advantageous place in line, plan to arrive early. 

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.

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.
