Some of the steepest terrain appears in the first few hundred yards until you get to the top.

Not too difficult until the last half mile. It's a nice hike and doable with a dog. Pretty crowded though, but we didnt start as early as I would like.

Fortuna Bear Super blood wolf moon total lunar eclipse. Awesome

Amazing hike to Potato Chip Rock, the wait wasn’t bad. People were very good about trading phones for pictures , if you took their picture , they would wait for your group to go out to the rock and take your picture. Some people complain about the wait, it’s not bad especially if you work as a team.

There’s a lot of misinformation on trail distance in the reviews. The trail is longer than described but not 14-15 miles. I hiked El Cajon Mtn today (second time) and my GPS read 11.8 miles round trip, which is consistent with my last trip up. Also, the total vertical gain is about 3,800 feet due to the trail dropping then gaining again and again. I’m a fan of this mighty little SoCal mountain due to its close proximity to SD and the ability it gives to train for its bigger brothers, or sisters, that lie north in the San Bernadinos and Sierras... minus the effects of altitude.

I love this trail, but man, was it packed with people and dogs this morning! There was some sort of wilderness course taking place as well. Few puddles from the recent rain, but nothing to derail you.

It took us around 3 hours but we had a slower dog in tow, so we moved somewhat slowly and stopped frequently.

Love this trail. The only thing people forget to mention is it’s ALL incline the entire way up!!! But well worth it. Great workout!

Great easy and beautiful hike!

Overall great hike, although two things are important to know for this one. First, I cannot recommend at all to drive into Pinyon Mountain Road with a normal car. I drove in with a Camry today and it was horrible. I almost got stuck once and had to push while my wife took over the wheel. Eventually we got out, but you might want a 4WD to drive there. Also the sand in the middle of the road gets quite high for the most part, such that we could hear it scratching the bottom of our car almost the entire way. Definitely come with a higher clearing and possible 4WD vehicle. The hike itself is easy apart from some stretches where you need to overcome some larger rocks on the way, but nothing serious. The real pain is finding the trail and staying on the trail. It’s very easy to lose track since there is no marker, only some piles of stones by your fellow hikers. Definitely a good idea to bring your phone/GPS device and keep track on where you’re going, which was a bit annoying for me. Other than that, great views and very typical desert landscape with lots of cactus.

This trail is an extension to Cowl’s Mountain. Tough hike due to the incline. Definitely a good workout!

Beautiful hike, gave it only 4 stars because there was a ~45 min wait to climb potato chip rock for a picture.

This was a nice trail to take my niece up, I believe she was 8 at the time. It was great that it was located straight across from our campground. Nice view from the top. Definitely worth checking out if you're in the area.

Good winter conditioning trail. Beautiful views. No snow or mud, even after all of the rain we received this week. The first two miles are single track and the rest is an old dirt service road. It is fairly exposed, which gives you great scenery to enjoy, but would be pretty brutal on a hot day. Nice if you are looking for solitude. I was out there for 8 hours. I didn't see any other hikers. Just two vehicles and 3 motorcycles. It was a rewarding hike, the tower has nice picnic facilities.

awesome views especially at the top will do it again after the rains stop in spring.

Great heart pumper to get your day going. Up and down in 38 minutes jogging/hiking. Trail running shoes help a lot with the rocky terrain. Dogs loved it! Only met 3 other people on a Friday morning. Pretty good for Mission trails which is always busy.

I really liked this trail, less people than the trail in San Carlos!

This trail was so steep! It was very hard, but the climb was worth the view!

Due to time constraints didn’t get to the top/fun Boulder portion of it, but we will. The trail itself is kick butt. Straight up hill the whole time. Loved it! Nice scenery too. The trail begins at a gate that is closed to vehicles and it looks like it says private property but it’s clearly not. Once you climb over that little fence, foot prints and dogs foot prints galore!

The regular road from the Pio Pico Campground was closed by Chula Vista city. If you go through the brown gate and then turn right to go up past the water tanks, the trail is pretty rocky and interesting. I did this in a stock Jeep tj and go stuck because I wasn’t running mid tires. I think if it was dry I would’ve been fine.
I didn’t follow the trail all the way but it seems to follow along a barbed wire fence.

It’s steeper than the other peaks in Mission Regional, but with a good pace, can use it as running trail for a real good work out

Hiked this trail on Sunday, Jan. 6, at midday. The weather was perfect: about 55 degrees and sunny, no jacket required. This is a great trail. It’s very pet-friendly but dogs must be on a leash. We took the less crowded route that starts in a residential area and it was amazing. The trail, while very rocky in many areas, is very well maintained. Make sure your paying attention to what’s coming up so you don’t trip. There are some steep parts that make not a good first hike, but it is doable by anyone who’s hiked steeper, longer trails. It took an hour to get to the top with stops along the way for photos. I’d do this trail again.

I underestimated how cold it was going to be. I would bring crampons if you have them.

We did this before sunset & it was really enjoyable from the top. It definitely can be busy, especially during the weekends, but it’s do-able. It was pretty easy. The incline wasn’t bad at all. Just watch footing for slippery rocks.

Great hike, beautiful views on the way up and down. Get ready for some steep up and downs the whole way. Took 5 hours round trip, 2:45 up, 2:15 down. 2 liters of water was plenty. Would be brutal during summer, highly recommend during winter months. Peak has nice rocks to have lunch at.

Awesome trail. Best I’ve done around San Diego area so far. Dripping Springs-Palomar Magee-Wild Horse took me 6.5 hours while running some stretches on the way down. A bit challenging and adventurous but definitely doable and more than worth it. Great diversity of surprisingly green scenery including oak and pine tree forests. Amazing views of snowcovered Jacinto, Gorgonio and Antonio. At a small section on Palomar Magee (maybe 0.3 miles) there are a couple of dead trees and shrub blocking the way, which actually made the trail a bit more primitive and adventurous to me. Nothing too hard to overcome though. Note that there is no real summit since the peak of the Cosley saddle is surrounded by lots of shrub, so no reason to stop. If you want to take a break, take it before or after the saddle at some of the views.

Stop in the visitor center and ask the volunteers to play the Ghost Mountain 15 minute movie before you head up. It gave us a different perspective after doing that.
Beautiful views and well marked trail in this protected area.

Good nature walk that keeps steep fast but a great view from the top. Crowded at beginning but empty by the end.
