Explore the most popular mountain biking trails in Alum Rock Park with hand-curated trail maps and driving directions as well as detailed reviews and photos from hikers, campers and nature lovers like you.

The lower parking lot was full, so I opted to drive back down to the neighborhood below. There is an upper parking lot that could work fine for a shorter hike.

The first half of the hike was a bit busy. It winds through little parks where people were having BBQ’s. I’ll probably come back and take advantage of that space, but it’s not like a quiet nature hike.

The second half along the upper rim trail was lovely. Not many people, and it hooked up along a ridge so you got some lovely views, including a view of the San Jose Valley.

I went in May and everything was blooming and beautiful.

Some of the signage could have been more clear. Ended up going a longer route and back tracking once or twice.

The trail map is wrong

Take the Penitencia Trail first and hook up to this trail up to Eagle Rock. There are beautiful meadows of mustard flowers carpeting the hills in Spring.

This is a stroller friendly stroll alongside a pretty shaded creek.

Beautiful place. Loved it

I'm used to mountain biking in Washington so maybe I'm a little biased, but I didn't love this as a mountain biking trail. Some great views at the top, but very little technical work required, mainly just brute leg strength. It was also a little too crowded to get any good speed up without someone being in your way. Not a bad ride, but also not great.

Good uphill climb, beautiful views!

Beautiful trail and managed well with a baby in the stroller and a toddler on foot. Also had my mom who uses a cane with me. Will be back!

Parked at rustic lands (free) and took the Penitencia creek trail east through the valley floor. Then we started on the north rim trailhead as indicated on this map. When you get to Eagle rock, look out for great views of circling hawks and turkey vultures. This actually ended up being a nice scenic loop because you can get back to rustic lands easily from Eagle rock (no need to backtrack to the trailhead).

Great morning hike with enough elevation to get the heart rate up. There's lots of shade but it's never too covered up. Tons of small wildlife scrabbling about.

Easy one

It’s a nice shaded trail that follows the creek. The creek has fish and leads up to mineral springs. We saw deer and hawks along the way!

Super fun single track when Penitencia Creek trail turns into South Rim trail. A little too much pavement and can be crowded along Penitencia Creek trail. Some of that can be avoided by taking the North Rim trail and connecting to South Rim.

My very first hike ever back in 2009. Starts off gorgeous, then the sun kicks your ass as you trail uphill lol it's a gorgeous hike with a well-earned view. Don't bring your rookie friends in this hike if you plan on making it to the top.

Fun but views are pretty steady

it a great way to get some fresh air love to run it very challenging beautiful views at top wildlife very open

Had an AWESOME tine with my family. Great for picnics, games, throwing a football then having a great walk with tons to look at and beautiful surroundings.

South rim trail is closed indefinitely, don't waste your time if you are heading there.

In summer the view become wee~dy, and its kind of boring. Some up and down so it's a good walk after work for me. Park in the rustic lands spot it's free and the youth center marked as the start here is NOT free.

There is a notice on the trail head saying south rim trail is closed due to 2017 winter storm.
