I've hiked to the labyrinths many times and had a great experience every time: rain, shine, fog and everything in between. The smaller labyrinths and spirals come and go as people make them with the many rocks in the park on hill tops and in...More

Nice park with map at entry gate. There are only 38 parking spots at sibley staging area, but is restroom, and cell coverage.

I don't know why TripAdvisor has a listing only for the labyrinth and not for the preserve as a whole. The labyrinth is interesting but ultimately ho-hum. The park has excellent trails leading through the forest and emerging at terrific viewpoints. I like going not...More

There are many of these in sibley. Sibley is a great place to hike. Bring a geologist for some real fun!

An easy walk (rocky but easy) from the Sibley parking lot on Skyline blvd (where there are toilets and water, plus a small exhibit). It's about 20 mins to get there, and you can loop to take a different walk back (caution this can be...More

Compared to regional parks and state parks in the east bay like Mt. Diablo, Briones, Las Trampas etc this Sibley is rather smaller hike. However it's got sunny parts and shady parts that make it convenient to hike in all seasons in Northern California.

Alll the labyrinths in Sibley should be seen. It is an adventure searching for the hidden labyrinths. All of them, the geological points of interest (pick up a printed guide), and the the views make this visit a very unique, educational and overall wonderful experience.

I never dreamed this labyrinth had a name! I know it for the newts that come out with the rains to mate and lay their eggs in the pond at the bottom. It's a nice destination for a walk, and a fun discovery for kids....More

The labyrinth is kind of cute, but not a reason to visit Robert Sibley Park. It's really just a bunch of rocks in a circle. The park has some nice hiking. It's off-leash for dogs, which is rare for the area. There are nice views...More

The area is a decent spot for a hike with views of the East Bay. The labyrinth itself, while interesting, isn't a reason to trek out, but is rather an unusual stop along the path.
