Are bikes permitted?
Be as green as our gardens and ride your bicycle to RBG. Timed parking fees do not apply to those arriving by bicycle, only motor vehicles.
Please note: For safety, maintenance, and conservation reasons, biking is not permitted on RBG’s trail systems. A secure bike locking station is available so you can leave your bike behind and enjoy a walk in nature. On our trails, bikes pose a direct threat to plants and ground-dwelling wild life, causes erosion, root death and tree dieback. This permanently alters nature’s balance by changing microclimates and paving the way for invasive species.

Dogs are welcome at the Arboretum and in the nature sanctuaries so long as they remain on-leash, on-trail, and are cleaned up after.
