|Views along Skyline Blvd if you approach Sibley from Berkeley.|
|If you're lucky, you will also get to enjoy a chorus of cows moo'ing (this was particularly exciting for the girls on our first visit to the park).|
|From the Sibley Staging Area, start your hike along the paved service road to the right of the visitors center.|
The best views of the Mazzariello labyrinth are from the northwest corner above the quarry, which you can access by walking along a small footpath that takes you to a higher vantage point of the quarry. On our first visit, this is where we turned around and called it a day (it was a late December morning and a very very cold 40 degrees out!). If you continue along that path, however, you will find yourself at another set of three labyrinths. Since we didn't take time to walk down to the bottom of the quarry for the first labyrinth, this was a fun chance to see the rock formations up close.
We continued along past the second set of labyrinths until the trail met up with the Volcanic Trail, which you can then use to cut back to the Round Top Trail Loop. Our first trip to the park was a simple out and back hike along the first portion of the Round Top Trail Loop. On our second visit, we did the entire Round Top Trail Loop, which takes you along a somewhat rocky dirt path through eucalyptus groves before it meets up with the trail you started on. This adds about a half mile to the hike and this portion of the trail can be particularly muddy if you are visiting shortly after heavy rains. Even if you aren't planning on doing the entire loop, it's worth climbing to the top of the hill that you will see just south of Overlook #2. The views of San Pablo Reservoir and the windmills in the distance are pretty amazing.
|The windmills of the Altamont Pass can be seen in the distance on a clear day.|
Have you hiked Sibley? Any trail recommendations?
Details: Sibley is located in the Oakland Hills off of Skyline Blvd. There is a small parking lot as well as street parking along the main road. During our visits during the winter there has been a bit of a temperature drop as we climbed the mountain, so bring layers.
