Our visit to this park was to see the San Luis Obispo Botanical Garden. Plans are in the works to expand the garden but at present it is very small and not really accessible to steep terrain and eroded paths.
Since the garden was so small we decided to check out the rest of the park and discovered a closed off, abandoned road that makes a excellent wheelchair accessible trail. The gate is wide enough for wheelchair access but the ground is a bit uneven which may make it difficult to hold the gate opened while maneuvering through the opening. Round trip distance is about 1 1/2 miles with a slight uphill rise so the return trip is downhill.
The parking lot for the garden is large enough for any RV. Walk/roll along the park road to get to the abandoned road or park in the dog park lot which is close to the gate and large enough for any RV. Park 35.33051, -120.72909
