Nature makes us healthy. The scientific basis for nature’s health benefits is now overwhelming. Study after peer-reviewed study has shown that nature exposure is linked to living longer, sleeping better, displaying improved cognitive function, and enjoying lower rates of heart disease, obesity, depression and stress. The Arboretum is a wonderful place to get into nature.

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 and Visa or Mastercard, but 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.

Getting Here

We're in San Bernardino National Forest between Lake Arrowhead and Running Springs. The main routes leading to Heaps Peak Arboretum are Highways 18 and 330. (Caltrans highway info: 800.427.7623.)

Semi-Annual Native Plant Sale

The Spring Native Plant Sale is on our calendar: Saturday, April 27! We hope you can drop by.

It is one of two plant sales that ROWIA holds each year, and is a major fundraiser for our group. The funds we raise will be used for maintenance and upkeep of the Arboretum. We are hoping to refresh the paint on the booth and signs, and replace signs that were damaged during last year’s blizzard.

The plant sale begins at 9:00 am, but buyers quite often line up as early as 7:30 am. The plants that we will have for sale are native to our area, and are purchased from a wholesaler that is known for its high-quality product. We are planning on having over 400 plants of 28 different varieties. 

Our aim in offering these plants for sale is to help our neighbors plant a perfect garden. According to the American Society of Landscape Architects, native plants require much less watering, fertilizer, and pesticides.  Native plants also create habitat and provide food for many different, native animals including birds, pollinators, and small mammals.

Remember, members receive a 20% discount. at the plant sale!

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!
