Next bird walk of the season is Saturday, June 15, at 8:00 am; binoculars are suggested. Jim Stone will be your guide.

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.

Bird Walks will be starting again on May 4 at 8:00 am. We have added a second bird walk each month, so now they will be held on both the first and third Saturdays of each month. Binoculars are suggested.

Friday , July 26, between 2:30 and 5:00 pm Rim Family Services will be hosting a Scavenger hunt at the Arboretum.

Explore the Forest

Improve your health at the Arboretum! 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. 

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!
