A quaint suburban route through the winding hills of Berkeley Hills that takes you past architectural wonders like Normandy Village and the Temple of Wings, with a terminus at the Lawrence Hall of Science after a short climb up a dusty hill trail. A real leg-burner with just under 1000ft of elevation gain, bring at least a bottle of water and be weary of traffic on Buena Vista Way. Empirically speaking, you have a 30% chance of seeing deer, especially at dusk. Great views of the bay from the top of the hill

Great hike as usual. We started at 6:30 am and down at the South Gate by 12:30 with an hour break at the top. Pretty warm day, 85 degree sun on the way down. Challenging hike as always. The last 2 miles to the summit is a narrow hike and on the way down we came across many other hikers going up, not everyone was wearing a mask. That made it tricky in the narrow trail sections. The 1.9 mile mark in the way up is slightly off, it should say 2.2 miles. For everyone going up, it doesn’t help to underestimate remaining distance. Every time I have done this trail, I found the rock city area confusion. Follow the trail map closely in this area.

Hard on the way up but beautiful vistas. Many cyclists on the path instead of on the road

Do this one early! Got to the park at 8:30 on a Monday and not too many people at all. Well worth the $10 park fee. We got lucky that we had cash on hand, because no one was at the welcome booth when we arrived.

Nice trail with decent incline towards the end. Like stated before not a lot of shade but it’s okay as there is a lot of wind.

This was one beast of a hike! Very hot with little to no cover on the way up. Very rocky in quite a few sections and very dusty! My wife and I definitely had to push ourselves on this one. We both had a great sense of accomplishment reaching the top!

Hike was definitely beautiful once to the top. Now the road going up, I was driving 10mph as recommended cause it’s very curvy but besides it was almost like we arrived on time for the gate to be opened at 7am, I like to do my hikes early in the morning with less folks. There was a fee of $10. The trail was Easy to moderate for myself and also my mom agreed. I drank about 1L of water. It was easy to follow the trial as well.

11.2 miles. The 6hrs estimate seems off. 4:10 hrs or 5hrs taking stops. Great hike. Recommend trail through time on way down to go through rock city and sentinel rock. Another hiker reported rattle snake. Great conditions today.

Nice constant hill on the way in Many bikes. Bike repair station at the entrance. Few signs on the trail to explain the geological formations in this park as well as the history of the area. Neat. Visitor center at the top Beautiful weather this time of year (around 60F). Western wallflower in bloom Poppies preparing their dress Had fun

I did a variation. Where it was more trailered to hiking. This trail is mostly road and recommended for road biking.

About 3/4 the way up there is caution tape. Just cross it and stick to the right side and you’ll be good. 01/7/2020

An excellent 8-miler filled with relentless uphill and breathtaking views. Not for the faint of heart: the way up is challenging and will test any experienced hiker. Best done in late fall-spring due to the milder temperature and likely cloud cover. Having a good moisture-wicking shirt and lightweight wind/rainbreaker will go a long way

Steep, challenging ascent and descent. Very little shade, but beautiful views overlooking the bay area. I started around 11a, reached the summit around 2, and was back at my campsite around 5. There were plenty of designated stops along the way — though be sure to bring water!

Good hike. Wouldn’t do it again in full sun. Would start earlier or later in the afternoon. Took us 2.5 hours to reach the summit going about 2 miles/hr.
