Facilities for Disabled Visitors
Restrooms – fully accessible.
The Visitor Center Shop and RSBG Nursery are fully accessible.
The accessibility path is level and covered with very fine, well compacted gravel. The route loops through our Rutherford Conservatory and adjoining terrace with nice benches to sit and enjoy being surrounded by nature and plants from around the world. The path continues through the Gazebo, another charming area to sit and gaze at the overview of the Garden. From there the path loops back around to the entrance, with a couple more benches along the way.
The rest of the Garden is partially accessible. Gravel paths and hilly terrain make the use of wheelchairs and walkers difficult through most of the Garden. Some people with walkers or motorized wheelchairs are able to travel down and back up some of our more gentle slopes.
