"booty hill" as I like to call it! one of my favorite local hikes.

Hiked this to train for Yosemite Half Dome. This was an awesome training hike. Your legs get a great workout. You need at least 3 liters of water. It was a sunny but windy and cool day when we hiked and I drank about 3, so on a hot day, would have needed more. Fox tails galore on the narrow paths, so stuck to my socks and shoes.

Perfect for dogs. Great for swimming with dogs. Came on a sunny Saturday in July and there were places where there were no people along the shore and we could swim without having to worry about our dogs disturbing other people and dogs. Excellent

Great trail when we did it in the spring. a different opinion from my hiking partner that day. He didn't enjoy the climbs. Much better spring or winter hike.

Started early to avoid the heat (the park opens at 6:00). Great run with tough uphills that turn into technical downhills. Closer to 21km according to my watch. Also some non cooperative cows and dry falls :-)

Good hike to test out some new gear, nice views. Paid $6 for parking, forgot it was a charged location but luckily they accept card. Ran into a few park staff very friendly, will be returning.

Did this trail in 3 days 2 nights starting at Mission Peak and ending at Del Valle.

Suggestions:

When? We did this hike yesterday (mid July), it was extremely hot and taxing. Very dry. Mid spring would be a better option.

Where? We started at Mission Peak which means we basically were climbing the entire way. When you start at Del Valle, the first ascent is extremely steep but you basically descend the rest of the way to MP. I would suggest starting from Del Valle.

Who? I suggest this trail to all ages over 13. This is really difficult physically and mentally at some points. Anyone younger I might assume would struggle. It says dogs are ok on a leash, but I would say not ok to bring a dog during summer. The trails, especially in the back country, are poorly maintained. There will be many stickers getting into your socks and their paws/fur.

Water? Bring an abundance or bring a stove. Although the map indicates potable water sources the three camps we stopped at to fill up did not have potable water. There was a relatively new sign on the water pipe saying it was untreated water and you must boil before drinking. Those campsites were School Camp in Sunol, Joes Horse Camp, and Maggie’s Half Acre. In addition to the misleading water sources also be advised that the water sources are not on the trail and are pretty far off. They are also down very steep hills.

Electricity and cell service? You’ll lose service once you get out of the Mission Peak area going into the trail. You won’t have any service the entire way until you hit the Del Valle trail systems. But then you’ll most likely lose service again in Del Valle itself. My suggestion would be to coordinate your pick-up location and time as precise as possible. The only electricity I was able to find was in Sunol on the backside of the Visitors Center building.

Wildlife? We encountered an abundance, especially in Sunol. Coyotes, raccoons, deer, vultures, Hawks, eagles, rabbits, rattle snakes, ground squirrels, free range cattle. Mosquitos and flies were especially abundant.

Food? Pack in and pack out. There are some places to throw trash away, so don’t worry about having to carry it for too long, you’ll eventually run into a campsite or rest stop with a trash can. But there will be absolutely no where to get food unless you get an Uber Eats to the MP trailhead. We under packed in terms of calories, therefore we were pretty sluggish at some points. So make sure you pack more calories than you usually eat in a day. We brought freeze dried meals that we bought from REI, boiled water with out propane camp stove, and enjoyed. We failed to bring a variety of other snacks however. I would also suggest bringing packets of powder Gatorade or similar, you’ll need the electrolytes.

Clothing? During mid July, I wore shorts the entire trip and was fine. My legs did get really dirty and I did get the occasional sticker but overall was ok. Next time I’ll bring pants for some of the deeper brush we went through. The nights get pretty cold even in the summer, so make sure to layer properly. We also brought lightweight hammocks, small sleeping bags, and roll up sleeping pads. Depending on where you decided to stop for the night there may or may not be trees convenient for putting up a hammock, or there may not be worthwhile ground for sleeping on.

Smoker? Don’t F’ing do it. California has enough wildfires. It’s strictly prohibited in all the parks anyway. However, we are all human and I’m sure it will be done. If that’s the case wait until you get next to a creek, water source, or in a campsite bathroom. Unless there’s a trash or a toilet, take your butt or roach with you.

I think this is all I can think of at the moment. I tried my best to record the trail as I did it, but like I mentioned the cellular signal was spotty and I was rationing battery life toward the middle of the hike. If there’s anything else you’d like to know please don’t hesitate to reach out.

Challenging with gorgeous scenery!

Hiked to Murietta Falls this past Saturday and it was 97 degrees. Very hot and we took the Ohlone Wilderness trail all the way there and didn't realize it was 18 miles round trip. Ran out of water last 4 miles coming back. It was a very hard hike especially with the heat. We started at 8:30 am and finished at 2:30 pm. No place to filter water either so carry a lot of water.

My favorite place to hike in the East Bay.

I love this trail I will come back to finish the trail

I explored so much of this area back in May!
In the end, I enjoyed the best views from a trail that was nestled a little before the park headquarters off the side of the road.
I had an amazing time running up, down, and along the hills.
Gorgeous views!

Nice loop with not so hard huffing to do. The walk by the lake was nice - that is where you will find a couple of restrooms and benches to look over the water. This trail is a lot easier than the Squirrel Gulch hike. Nothing real steep and the views are stunning. Some wildlife including the same doe I spotted last month.

Very difficult hike with some parts fire roads and some very narrow, over grown single tracks. 11.8 miles took us 4.5 hours so you need to leave early in the morning to avoid the hot sun.

A nice wide trail all the way around. I saw raptors, baby snakes, a deer, ground squirrels, and mallards in one of the ponds.

Like others have said, this trail has it's steep parts. I found Squirrel Gulch to be the most heart pounding. The rest of the trails even out pretty much, but be wary, it does have some steep parts past Squirrel Gulch Trail. This loop gave me a good workout, and I will be back to try it again to see how my fitness gains/losses go this summer.

While most of the human activity is in the water down below, I did see a fair amount of mt bikers and other hikers. But, I had the trail mainly to myself and I enjoyed the scenery very much. The top of the hills to the west still had a little green on them.

There is some shade throughout, so you aren't walking in the sun the whole time. Thankfully I was able to stand in shade and let a nice breeze cool me down. Take plenty of water as I did not see anything potable on the trails. Since it is warming up, I highly suggest doing this very early in the morning, as it gets hot quickly.

There was no phone signal, so I was unable to do a alltrails recording.

5-22-18 I started around 0830 and was back at my car around 1430.
This hike is very tough. I was the only one on the trail, I did not see anyone else. lots of great scenery. but the falls were dried up but i figured that going into the hike. i would recommend hiking poles to help. I took 3 liters of water and i had it finished by the last mile or so. There is a lake and after my hike it was nice to relax and dip my feet in. Overall I would recommend this hike.

5-12-18. Hiked as part of a longer hike to catch the county highpoint of Alameda. I paid the $6 parking fee, and the $2 wilderness permit and parked at the campground with permission. I feared that the hills would turn brown, but they hadn't yet. It was amazing to see all the variety of flowers. Climbed to the top of rocky ridget, and enjoyed seeing that as a reference point along the Big Burn. Schleper Rock was fun to scramble on. The falls however were all dried up, leaving only a trickle. The hills are challenge, but a fit or determined person would be fine for the hike. The Ohlone Wilderness is special.

Nice 5 mile loop. combination of wide fire road as well as single track with a few very steep hills. Best to go counter clock wise. This is a moderate to difficult hike.

It’s a pretty trail, but not a lot of shade, any time of the year but summer. Saw a lot of wild life, deer, huge birds (careful with small dogs) we had two and the bird kept circling us and at one point came so close to the grown it scared us. We picked up our dogs until it went away. We also saw wild turkeys and cows. Spectacular views!

Nice 3.5 Mile loop that gets you close to the lake. When you get to the bottom you can take the trail down to the lake if you want to see it.

Nice loop, gets you down to the lake and back

it's a brutal hike but totally loved it!! I will definitely recommend !! best workout ever for the lungs, heart and legs and mind those brutal hills won't let you think

Awesome trail with great views and wild life encounters. Off leash dogs allowed.
Will come back.

I backpacked the trail from Mission Peak to Del Valle in three days/two nights, with overnights at Sunol Backpacking Camp (Sky Camp is absolutely magical) and Maggie’s Half Acre (site #1 is the most secluded). I went in late March and already it was a bit warmer than preferred, but I saw some great wildflowers and the hills were green from winter rains. I had no problem finding water to filter at this time of year. Sunol is not the prettiest park, but Ohlone Wilderness and Del Valle are absolute delights. I would recommend hiking from west to east to avoid hiking uphill in Del Valle — going downhill was brutal on my knees but I think the exertion on a hot day with full pack would have been worse! This trail is a great physical challenge and adventure given its proximity to the Bay Area — I even took BART/Lyft to the Mission Peak trailhead!

Came here for the elevation gain as part of our Mt Whitney training. The falls was a side trip and as expected, it’s nothing grand but just a nice place to take a break and eat lunch. Otherwise, this is an awesome incline hike with endless rolling hills. Trekking poles recommended but not required. The skies were blue and no clouds in sight yet the weather was perfect on this April day and there was enough wind to cool us off for the killer ascents. I brought 4 liter of water but only consumed 1.25. I’ll give it 4 stars for the terrain and 1 star for the falls.

This was my longest hike since I took up the hobby 2 years ago. I've actually never done a marathon, and this was a marathon with a 7500 ft climb, which is pretty insane. But I like a challenge, so wth.

Most people will backpack the Ohlone Wilderness Trail and everyone I passed out in the backcountry was doing just that. That would be my suggestion to people who don't think they can do the hike in one day. I'm not a backpacker, so I just went for it, with an option to bail at the 20 mile mark when I reached Sunol.

I got an early start from Del Valle around 6:30 because I wanted to have the sun at my back for as long as possible. I didn't see any other people until about 8 miles in where I passed 4 backpackers. By the time I hit Rose Peak I was feeling it and can understand why it's suggested to camp out overnight at nearby Maggie's Half Acre.

But what comes up, must come down, and after Rose Peak, it's pretty much all downhill until you reach Sunol. There is a gulch you drop down into briefly, but it's not too bad. Along the way, I was greeted with beautiful orange poppies and assorted wildflowers. It was mid-April, so everything was blooming.

I was hoping to fill up on water in Sunol, but the fountains along the trail weren't working. I probably should have searched around some more at the Sunol park headquarters, because I ran out of water about half-way up the back side of Mission Peak and there isn't any running water until you reach the Stanford Ave. staging area. So that was unfortunate and slowed me down near the end. I was hoping to finish in under 9 hours, but ran over a little.

All in all, what a workout! I weighed in when I got home and lost 4 lbs during the hike. I would recommend doing it east to west and not the opposite because I didn't get too much sun on my face this way. It was a cool April day, so I wore a hoodie the whole time (especially at elevation). I wanted to get this hike in before it got hot and it worked out great! Plus as others have said, you want to get the hard part out of the way first. Believe it or not, Mission Peak is the easier part of the hike.

Amazing views of the mountains and canyons.Its’s a very challenging hike with an elevation gain of 4200+ feet.Make sure to start super early .Trekking poles highly recommend.Bring plenty of water and sunblock..Although not a lot of water flowing in the falls it still looks so beautiful.Excellent teaming ground and the view is well worth it.
