Definitely counterclockwise direction. It was a smooth way back down to parking lot. Mud, cow poop and wet grass is abundant depending on (writing this down in January) climate. We did enjoy this hike. Bring proper shoes and walking sticks were also helpful.

I highly recommend completing the hike counterclockwise. The trail was fairly muddy so I’d recommend shoes that can be washed easily. There is a lot of wildlife on the trail including ground squirrels and cattle. Horses are allowed to use the trail so watch your step. Dogs are not allowed. Keep in mind half your hike is uphill. Enjoy!

We went for a weekend hike in November and really enjoyed it! Did the counterclockwise route as suggested and would recommend it as well. For most of the walk we didn’t run into others. Nice open spaces, Wild turkeys, and good views at the top.

I really enjoyed this ike. Loved the views, reminded me of England

Good trail but only problem is a lot of poop on trail. So winter time is ok but summertime is smelly Except that it is good hiking place near Bay Area

Beautiful views, a couple killer climbs. Definitely bring hydration and chews/snacks for fuel.

Great views! Very challenging and varied terrain but, easy to follow marked routes. I used this as a trail run but, would definitely recommend for hiking or birding.

Definitely bring sufficient hydration.

First time hiking this trail and I really enjoyed it. Got kind of a late start (2:30pm) so didn't run into many people. Took counterclockwise route; glad I did as that was the more strenuous, so got it out of the way! Beautiful views, lots of animal tracks - saw some deer. Will definitely hike it again.

Beautiful views. Lightly traveled trail by hikers and runners. We rode horseback the Miwok Trail first, then the Hardy Canyon. Would suggest the reverse, Hardy first to Miwok. Do the canyon early when the sun is low and then Miwok should be in the shade on the way down. On horseback the Hardy has many sandstone outcrops, they aren't slippery, but very challenging if you are going down them, up would be better. This is not a beginner trail for horses.

Went today for the first time. It's wasn't so packed as we thought it was. Not alot of bikers or runner, some people here and there. great hike for those who hasn't hike for the longest. It is a great warm up.

It's been almost 10 year but it was one of my old winter hiking areas halfway to the gf's house.

Great winter hike I've done many times. Hardly anyone there. My gf and I once followed a kit fox on the trail for a 1/2 mile while he constantly looked over his shoulder at us. Pretty funny...

Dry and hot... Best done as a winter trail.

Great hike, look forward to going again.

best done in spring when the creeks are flowing freely

I love this trail! Would be a five star except it has a lot of people on it. Lots of trail runners that come right up on from behind you without any warning. Lots of fitness types on the trail. I expected it would be crowded because it is free to park and nearby Brentwood. Wouldn't mind the people so much, but there were some really loud talkers!

The trail is nice and wide in most spots. I saw lots of turkeys both Toms roosting, and hens with the babies. They should rename it to Turkey Hill as there are a lot of them here! Very beautiful scenery to soak up.

Take water with you - there is some shade, but not in a lot of places.. Hold your nose in the toilet. I like the trail and will be back in the winter when the hills are green again.

I went counterclockwise so the ascent was really that abrupt than the clockwise path. It was my first time but I'll do it again someday.

Nice hike with lots of intermittent shade for a reprieve from the sun. Lots of gradual up and down as opposed to straight up. Pretty views. Great hike for a beginner like me.

great for some easy mountain biking

Coolest and quietest place...just perfect

Beautiful views, definitely good to bring lots of water and trekking poles for the hike back up the mountain. Another good thing to know is that this trail is highly trafficked. Be prepared for people running at you when there is nowhere to go

numerous changing of path ups n downs

It's a beautiful hiking trail. With beautiful views..

no dogs on nature trail will always get a low rating for me...its outside people

I love this trail. It's challenging enough but overall not too bad. I've hiked it alone and with friends and my kids. Great views of the surrounding preserve from the midway point at the top. If you do the trail reverse starting on Hardy Canyon it definitely makes it more challenging. Muddy after rain but you can still do it. Enjoy!

Great hike. We started at the trailhead at Round Valley and went 5 miles to the lake and then returned 5 miles for a total of 10 miles. The trail is mostly flat with a hill at the beginning and about 3/4 mile before the lake. There is very little to no shade. The temperature was in the 50’s today with a slight breeze. Perfect for the hike today. Got to see lots of wildlife - wild turkeys and coyotes - as well as cows and several people riding horses.

Hiked this trail yesterday afternoon. Was very nice, only crossed path with one other person the entire hike. Will come back again.
