Celebrating 40 years

HEAPS PEAK
ARBORETUM

Hours & Events

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.

The booth is open from 11 AM - 3 PM Saturdays and Sundays. We accept cash, Visa, MasterCard, American Express, ApplePay and GooglePay. There is a $1 service fee for non-cash purchases, no minimums.

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 openAs always, entrance to the Arboretum itself is free.

Directions & Parking

Adding native plants to your garden can...

  • reduce yard work.
  • lower water bills.
  • mitigate fire risk.
  • increase biodiversity.
  • help endangered animals.

Some animals need specific native plants to survive. One well-known example is monach butterflies, who would die out without milkweed. Adding native plants to your garden, no matter how small, can make a difference to you and your community, and we’re here to help!

Explore and Restore

Improve your health at the Arboretum! Study after peer-reviewed study has shown that nature exposure is linked to:

  • better sleep
  • better cognitive function
  • improved mood
  • decreased stress

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!
