Heaps Peak Arboretum

Located in the San Bernardino National Forest, the story of Heaps Park Arboretum includes tales of it serving as a lumber cutting operation before being restored as a forest. Then, following a fire in the mid- 1950s, it became a dumping ground for locals. In the mid-1980s, a group of volunteers cleaned it up, planted trees, and turned it into what we know today – a beautiful natural attraction with walking trails and a plethora of beautiful trees.

With 30 species of plants native to California, you’ll view a variety of colorful flowers among the trees, shrubs, and other plants. The paths are easily accessible for walkers of all ages, as well as strollers. Fall is also a great time to visit Heaps Peak Arboretum and see the autumn leaves.
