The view is great. Many trails to choose from. You can even go to the Alum Rock Park from here. The only reason I didn’t give a 5-star rating is that the trials are not shaded. Could be too hot in the summer. Bring some water with you.

Great park with amazing views - of neighboring hills, san jose and even south bay. The trails rarely stay on the same level due to the nature of the terrain, so prepare for some elevation gain. Very little shade, so wear sunscreen and/or wide hat in summer months.

Amazing view! Beautiful vista point to overlook the entire Silicone Valley! Worth the trip!

Unbelievable View! A must see at Sunset! Get there at 530p as spots are limited for parking! Gates get locked at 6p and you can stay until 7p to see the sunset! Ron the park ranger was awesome and easy to talk with! Thanks Ron!

Beautiful views! You can see most of the San Jose area, and part of the San Francisco Bay. Especially stunning at sunset. Even if youre not gonna take a hike, it is worth the drive to sit at the top.

Get away for a nice long hike. Plenty of online and offline pdf maps for this preserve. Go early, its going to take longer than planned.

Wonderful views of the South Bay. Parking is limited. Since you start on the top of the mountain be prepared to hike back up. There is little to no shade. Bring water.It is not very busy typically. However watch out for mountain bikers sharing the same multi use trails.

It was awesome to trailing without family and they are closing 6 pm . So you need to do morning or afternoon to start up, staffs at the parking are friendly and informative.

This is a great place to visit. It has nice city views and trails for hiking. Along the way you can see many horses. Its a popular place and busy during weekends. At night the city view is really great.On the trails the mountain views are awesome.Plenty of parking spots there.

Just what it sounds like: an open space on top of a hill. On the plus side it has a great view of the valley. There is a short hiking trail in a circle. There is also a much longer trail that connects to Alum Rock Park. Overall pleasent but not extensive.

Great place to come during quarantine. Just be mindful that there are no dogs allowed because there is livestock and horses are allowed to be in the trail. It is a total of about 14 miles to do the whole trail so please bring lots of water if you plan to take it on. You can see all of San Jose from here and if you take the trail to the left of the parking lot you are able to see San Fransisco.

Many good hiking trails for different levels. I would go early in the morning or during the fall/spring seasons to avoid the heat (not lot of shades). Try the Boccardo Spur Trail to reach the top and good view of down town San Jose.

One of the best view in the bay for sunset. It is also great for sunrises. It can be very chilly. A light jacket can fix that. Watch out the gate open ours and parki g is limited

Love this place, with limited parking so be patient and find a spot.

This was actually quite the experience and a good workout. Come early enough the gates close at 6pm. I loved the scenic views and the ability to be ably to get the workout I need even during this time. Was not busy but I assume during the morning it would be.

Awesome drive to hill-top...

As always best sunset spot... But only open till 6PM(Due to covid19?).. so not possible to view sunset from that spot....Very limited parking..

Good location to get in a few miles hike in. Not a lot of parking, so go early

Open space on a beautiful mountain. Pretty close to city, only 30mins drive from city center. This place got a great view of the city. Beautiful during night, best place to watch the sun set from across the valley! Pretty cold during cloudy days. Mountain roads are fun to drive! Only challenge is to get some good pics while driving uphill, there is no parking along the way !

Views here are spectacular. I definitely recommend. There are various viewpoints going up sierra road. Parking can be tough but there should be enough space on the side of curves to park.

Amazing place to visit near to San Jose. The narrow roads between hills surrounded by beautiful clouds. Its breathtaking place. After reaching the top park your car and walk and enjoy the hike. There were some cyclists you come across. I think its little rush during weekends. Must visit place between 10 am to 3 PM. Thanks to our friend Ramu for showing this awesome place.

Great views from the top of the preserve. Bay-area ridge trail overlooks a beautiful view of the south-bay. This place will be closed for the 4th July weekend 2020 due to Covid19. Regular days the park closes at 6pm.

Super dry, hot, and windy but so beautiful.

Great views. Lots of cows. Very windy.

I love running the trails at Sierra Vista Open Space! Many hike or ride their mountain bikes here. It’s best to go before 8 am during the Summer as some of the trails have little shade. The rest of the year anytime is good. There is a small parking lot that can accommodate about 20 cars. There are no restrooms.

Met with coyote. Nice one

Beautiful local county park. I went up this week to view comet Neowise. Be careful though, good amount of street racers speeding on the roads.

Its a good place for views, hiking, a place of clear your mind, and peace be it external or internal.

Come wat before 6pm so you have enough time to get a good hike in. Scenic views not a lot of people and offers a great view of the city. Great work out and great walk through areas where you can see cows and horses, breathtaking and very full of nature.

Great views of the city. You can see the whole night sky. Looks beautiful at night with the

One of the best location to catch sunrise in the south bay area. The area is open, and plenty of parking. Just keep in mind they only open at 8:00 A.M.. But keep in mind if you go beyond the parking, there is some narrow one lane road ahead... Just be careful.

It has atleast 4 different trails for all types of difficulty and length. With some famous view points overlooking the South Bay area and good parking, it is a delight to your eyes as well as the hiker inside you. Alum Rock provides good connectivity and a number of trails which should be experienced if you are near South Bay. Mission peak is obviously the most famous and strenuous, but this can be the second best.

Nice place. Road is very windy from one side and one way for two cars on the other side to it. So be careful. Also very steep. Lots of trails. Short and long from 1.2 m to 9 m. Very picturistic. Parking is free.

Nice hiking trails. Beautiful views of the bay area.

Best place for hikes, but best views are winter and spring. Now its all dry without shade

Nice and cool, but dont forget to wear your thermals, or you may freeze

Great cool weather hiking. Very little shade, but plenty spectacular views, especially when the wind has blown the smog away.

Beautiful views over San Jose. We drove up by car in the evening and watched the sunset over the city.

This is really nice place for hiking. Specially if you go around sun set time, you can see entire silicon valley. Depending on the clouds you may end up catching spectacular sunsets. There is a reasonably big parking lot near the trail head, you will generally find parking there. There are several trails, there is a trail which ends up in view point, where you can see entire bay area, on a clear day you can even see San Francisco and Oakland skyline.

Beautiful views and challenging trails!

Lovely place. The road up there is a bit tight, but nothing compared to San Francisco. Just avoid looking around too much if youre scared of heights. Great place for car enthusiast, just stay in your lane. The trails are awesome. The one I went on was fantastic and doable for a guy that doesnt workout anymore. Will be coming back.

I love the sunset here

Parking is very limited but its a great place to go on a walk

Sierra Road is so fun to drive! It’s super windy on the hill. But a great spot to watch sunset/sunrise. :) There are several trails.

I visited there in March. I loved the idyllic scene of meadows as far as the eye could see. Also, there is a city over the meadows.We parked Sierra Vista Point and walked the Kestrel Trail and Sierra Vista Trail.There is no shade and no restroom.

Nice place for small hikes. Go in groups, take water and avoid sun in summer!!!

I didnt go on any of the trails as it was way too hot, but the awesome view of looking down San Jose and the bays salt flats is something to see!

Awsome trails! Fun time for all types of hikes.

Very pretty views of the valley and the surrounding mountains. Open for hiking or biking. Some of the paths can be pretty steep at times.

Nice view at 2,000 feet. Trails for hiking, trash cans, information board. Small parking lot and no bathroom or water. What do people do when they need to go to the bathroom? Bushes are not very big and trees are sparse and small. I guess you have be daring on the trail to relieve yourself. Watch out for ticks and stay on the trail.

The best place to observe the power and virginity of the Bay Area

My wife & I visited for the 1st time 1/17/2020. We enjoyed it. Between 1130am-3pm, we hiked the Upper Calaveras Fault Trail, the Sierra Vista Trail & the Aquila Loop Trail. Very green. Snowy peaks in the nearby distance. Saw 2 coyotes. Lots of birds. Flowers coming into bloom. We had lunch at some of the benches & picnic tables they have setup. Some parts of these trails are steep but nothing too bad for us. It was worth the drive. We got a ride share in & out. There is a parking lot on the west end.

Parking is limited, but once you walk away from the parking area it can be a mostly quiet place to walk. Highly recommend going up to see the sunset.

Beautiful views. Good for kids hiking as well. I hiked with my 2.5 and 6.5yr olds and they loved it.

Great place for hiking, running & biking. The car & moto drive is a perfect option for non-sportive ones.

Thought it was just perfect for a quick hike. Beautiful views of San Jose. Was a overcast day just after light shower so trail was a little muddy but manageable. Hiked the Aquila trail. No shade for the most part but amazing view.

Its a really nice place to hike. Especially lower and upper calaveras trail. The entire route has a great view of the city. Much preferred between Feb to April.

This preserve offers fantastic views and relatively easy hikes.

This is one of the best places to enjoy the sunset of sierra mountain without driving hours out of the town. It is quite enjoyable to talk a hike in the nearby trail with your camera, or dog.

Beautiful view and good hike

Great views and a nice long trail. Ride is steep, but enjoyable

This spring we cannot see the snow peaks at the east side when we were hiking on the hill, its clear the climate change warm today.

Sunset is so amazing, sometimes it’s bit windy so carry light jacket. Peaceful and close to nature.

Amazing views and some fantastic hiking trails

Is so beautiful after so much rain, there are flowers and is all green! The views of the valley are amaizing and with miles of trails.

Such an amazinh trail with breathtaking landscape

Great for an easy hike, you can drive right up to the trail head where you get a great view covering the heart of Silicon Valley. Granted I was there on a hazy, over 100 degree day. The only problem is the hike starts downhill so its all uphill back to your car.

Beautiful place for a walk. I recommend taking the Calaveras route if you want peace and quiet as less people go that route. Also very challenging with very steep inclines

One of the best spots in the bay area!

Always have a nice time & hike here. The cows are awesome and the sunset is even better.

Beautiful views in the evening and a very good place to spend during sunset. Carry some water, jackets if youre going in the winter and enjoy the views from there. This place closes soon after sunset.

A fantastic place to get sweeping mountain vistas, city views, and sunset shots. There are different trails to choose from. Hike, bike, or ride a horse...one can their pick. Trails from here also connect to Alum Rock Parks Boccardo trail. Parking is limited so it could be a bummer. The road up to this place is a narrow mountain road. One can see lots of cows and horses on the way up. If you want to drive in the back roads, Sierra Rd connects to the road going to the Calaveras County Park. Sierra Rd. Was constant race route during the early years of the Amgen Tour of California.

Great place. Beautiful Vista and views of San Jose, Mission Peak and Mount Hamilton.

Amazing views great trails. Only complaint is irresponsible pet owners who dont pick up after their dogs.

Nice place. Not crowded much, get away from regular city traffic. You can get a nice view of the city when there arent many clouds.

Not nearly enough parking. Be prepared to circle for a bit.

Really peaceful, lots of trails, and would recommend even in sub-par weather. The drive up is fun too, great for a motorcycle.

Great views with good climbs. Lots of mountain bikes on the trails. Very few trees so make sure you use sunscreen on sunny days and bring plenty of water on hot days. The climbs were pretty steep, so make sure youre in good shape to make the climbs before attempting this trail.

Amazing view in the foggy morning!

Views are spectacular, while coming down remember to put the car in 1st gear otherwise wear and tear will happen to breaks and you can literally see smile coming out from the front breaks, you can even set the speed 15mph to cruise control.. DO NOT DRIVE the car on D mode...

The view of San Jose downtown is nice, the rolling hills offer a pleasant trek for families. There is hardly any crowd. The grass is light and green in December and November. There are multiple trail paths.

Amazing views. Look at the weather before going.

What a beautiful place to see sunset and the drive to the point is just . You can go hiking too but see advisory for high winds and rain (we werent so smart) .

The best open reserve in South Bay that gives unobstructed view of San Jose

Great trails for new hiker.

Beautiful view of the sunset and plenty of hiking trails around the area. Part of the road is one lane and has potholes.

Beautiful scenery and peaceful as well

A beautiful view of Silicon Valley

Amazing place to get some fresh air and. A good leg workout.

Beautiful views of the Bay Area. A must visit!

It should be explored,especially now in these challenging times for a rehumanizing experience that sometimes only nature can impart.

Great place for hikes. Better than Fremont peaks because less number of people. If its a sunny day, you can see hand gliders. They have a fishing pond full of Bass (need a fishing license). Grilling and picnic spot is first come first serve basis. Toilets available.

Great hike. You get great views throughout the hike. However, you start by hiking down which makes the last part of the hike uphill. We wanted something a bit easier than mission peak and this was perfect (easier but not easy).

Good and small hike a pleasant early morning in the weekend.

Easy to access, unprecedented views!

Nice place for sunset!! Bring extra warm clothes it’s so windy up there

I love visiting this place. It has few trails. Beautiful place. I usually spend 1-1.5 hours here. It usually closes by 7 -7:30pm. Its too windy here. Dont forget to carry the jacket.

Beautiful view of Silicon valley. It has a nice trail, but it was steep in some areas. Take water....I did not and wish I had.

Loved the hike. It was an easy one with family. Living in seattle for 15 yrs and hiking some big mountains, we went with big excitement. It was nice little hill :)

Amazing views and easy parking. I reccomend to stay on the designated trails because they have rangers circulating checking for illegal off trail usage. Have fun!
