Weir Canyon Wilderness Park

This trail has quickly become my favorite hiking trail in OC. Went around 9am on a Saturday and it wasn’t too crowded. I was almost hesitant to review because I don’t want more people knowing about it and it getting too crowded. Lol. It’s a gorgeous trail in the canyon. Very secluded and I love that it feels like you’re far from civilization. Brought my dachshund (aka wiener dog) with me and he enjoyed it also. Free parking and there was plenty of it when I went. My only complaint is I wish there were more signs telling me where to go and how many miles it will be. There’s many trails you can take and you don’t know how long you’ll be going. When I went, we took the trail on the left when you first enter. I didn’t think about reading more reviews to see where to go. We had no idea if it was going to loop around or not so we ended up just going back. However, no biggie. We just have a better idea of where to go next time. Overall, my boyfriend, my dog, and I love this trail and plan to go again this weekend. :)

Had a great hike here with my dog. Trails were easy to stay on. Only down side is there aren’t any signs saying how long the trails are or how difficult they are. Beautiful scenery. Theres not a parking lot, have to park on a street in front of houses.

We had a great hike here! It’s not very «wildernessy» (there aren’t many spots where you can’t see houses or other man-​made objects) but it is moderately difficult! We saw and heard lots of birds, and there are some beautiful views.

The area itself and the drive to the park are really nice. I went on a weekday, and there was only one other car there when I arrived. Parking and the park are free. It’s really more a canyon and not a park, if you’re thinking about it in the traditional sense.
I just started walking, and I wasn’t too sure where I was going. The trail signs are pretty uninformative here. You don’t know which routes to take or how long each route will be (unless you do research beforehand — I only read other Unilocal reviews, which apparently wasn’t enough), and the trails are so windy, it gets really confusing! I started walking down the Weir Canyon route, and I saw some other routes branching off, and I never knew which one to take! It turned into an adventure, but not one I was looking for at the moment. I also started to freak myself out because I went alone, I didn’t know where I was going, and there was absolutely no one around! I was SO glad I used Map My Run because otherwise, I would’ve been lost and unsure if I was heading back the right way or not. I kept wondering if I should just turn back the way I came or not. I also lost cell reception when I was out there, but luckily the GPS signal for Map My Run doesn’t go out with cell reception.
The trails themselves are windy, some flat, some inclined, which keeps it a little more interesting. It wasn’t too intense. You can bike here as well. Also, there’s no shade, so I did pick a cloudy day to go.
There were a lot of insects all over the place, and they liked to fly around me which was quite annoying; tons of ants all over the ground — don’t attempt to sit down or touch anything; I could hear but didn’t actually see any rattlesnakes.
The view is pretty nice, but my frustrations kinda took over and stole my enjoyment halfway through. I finally made it back 2 hours and 5.3 miles later. I was hoping to catch one of those 4 mile loops all these other Unilocalers are mentioning, but I just didn’t know which trails to take!!! Am I alone in this???

Just recently found this place and I am glad I did. You would never know this trail existed because the trail is kind of hidden in a nice residential area in Anaheim Hills.
Nonetheless, the trail and hike was a good hour and 30 mins. It goes around pretty windy but at the end when you reach the top, you get a beautiful view of Anaheim hills. Definitely rewarding!

This hike was pretty intense at times but my friend and I took it slow. It turned out to be a little more than 5 miles for us. There is no shade at all and you definitely need a lot of water. Overall this was a gorgeous hike with amazing views!

Weir Canyon loop is approximately 3.8 miles. As a mountain biker it provided a great cardio work out especially if you ride it counter clock wise. Steep gradual hills with short semi technical down hills make the ride fun and challenging. If you want a longer ride, take the loop down into Santiago Oaks. Arrive early it does get busy with hikers.

The best things in life are free. For me, this is one of them. I love coming here for my alone time or to watch the Sunset. When I’m here, the only thing I need with me is my Iphone for my Spotify playlist and my pepper spray just in case a Mountain Lion tries to eat me. Though I’ve only heard through the Grapevine of Mountain Lion sightings, I’ve never actually seen one. Better to be safe then sorry.
4 mile hiking adventure with great views, little loops, high hills, low hills and plenty of open area. It’s a nice hidden gem where you can easily get away from everything for an hour or two.
You’ll see walkers, joggers, dog walkers, mountain bikers and maybe even some wildlife. Just be cautious of dangerous spiders or snakes on the move. I almost fainted when a snake slid right past me during one of my hikes.
The trail is great to visit year round, but Fall is the best time to go. As during Summer the weather gets too hot and in Winter the trail tends to get wet and muddy.
This is a good place for beginners and experienced hikers. The inclines can be challenging for the beginners, but it’s still a great workout.
Definitely would recommend this to everyone whose thinking about coming to Weir Canyon Wilderness Park. Great little adventure with beautiful scenery.

One of my favorite trails! Last time I did the 4 mile loop and it was great. I would say it’s a pretty moderate hike, great for the family.
I can imagine it can get really hot during summer since there aren’t any shades. But if you get there early in the morning or later in the evening then you should be fine.

4 Miles Loop — Moderate — My 2^nd time on this hike.
1^st time, was in summer over 90’s in morning. It’s too hot, too dry and no shade. Nothing much there to see. And A lot of incline depend on which direction go to.
2^nd time at end of April, it’s great. We started the hike after 5 pm and watch the sunset. Nice cool air even with sun still out. Everywhere is so green & wild flowers bloom. Old Weir Canyon Trail cover with yellow wild flowers. Its so pretty.
If you want challenge do 4 mile Loop — Start with Weir Canyon trail which 1^st incline and go straight. Follow the trail sign. This way is mostly incline
If you want cut the hike short — smaller loop — take Weir Canyon to Deer ?? (I forgot exact name) back to Weir Canyon
If you just want to go for Sunset — Challenge short hike — On Weir Canyon trail 1^st incline take left fork trail to Old Weir Canyon Trail to Weir Canyon. Stop @ Overview of the city with wooden fence on right
If you want easier hike to see Sunset — a little longer hike than above — On Weir Canyon trail 1^st incline take left fork trail. Stop @ Overview of the city with wooden fence on right
Its took me a little over 2 ½ hours on this hike and took over 250 pics.

How lovely it is in Southern California to be a short drive from a place devoid of concrete and traffic. For people in and around Anaheim Hills, Weir Canyon Wilderness Park is just such a place.
With a trail head hidden in a rather posh neighborhood near the top of a pretty hillside rests Weir Canyon Wilderness Park. It welcomes all: walkers, joggers, mountain bikers, and even dogs.
The spring is the prettiest time at Weir Canyon. The grass is green, the wild flowers are out, and the sky is such a lovely shade of blue. Spring also brings hiking weather to the park, as does the fall. In the summer, evenings are nice when the heat cools some. Winter is generally good, but beware of hiking after a rain. This place can get pretty muddy.
If you just want a short jaunt and aren’t into fitness, you can take a little loop to the left that heads up a small hill, gives a nice view, and turns you back around to the car. If you prefer more of a stretch, you can hike all the way to Tustin from here. I’m in the middle and have a favorite loop that takes me up a couple good hills, gives a lovely view, catches a breeze after the most strenuous part, and gives me a 5 mile trip into relaxation.
I have found my fellow outdoor lovers here to be polite and friendly. The dogs have all been nice and the owners must be taking their poop bags with them. The trail is generally tidy. Mountain bikers are thoughtful of others and even say thanks when we step to the side to let them pass.
Sure, it’s hot in the summer. It’s muddy after a rain. However, it’s a bit stretch of green space just a short drive away. Weir Canyon is a favorite with our family.

I checked out Weir Canyon on a Sunday afternoon and just a note, bring water! It got very hot very quickly.
I did about 3.50 miles of the trail. Some of the hills are steep and can be a little tricky. Coming down there can be loose dirt, gravel and you’ll end up surfing the dirt on your ass all the way down if you’re not careful. It did not happen to me but my nephew got to experience a little bit of it.
Nice views of Orange County, saw some hares, squirrels, lizards and unfortunately witnessed a dog pass out. Luckily the owners were able to help their dog and got him to safety.
Free parking street parking and even though some of the reviews call it the «Secret Park» it was fairly easy to find. If you are a semi-​beginning intermediate hiker I recommend this trail.

Weir Canyon is sometimes called the «secret park» that not many people know of because it’s right next to a residential area.
Coordinates for this hike: Lat:33.83 052 Lon:-117.74 543
Terrain: This trail is uneven, with several up-​and-​down hills.
DISTANCE & ELEVATION GAIN: 4 miles taking approximately 2 hours to complete;
depending on the group pace this day. Gain +/​-​340 ft.
PACE: Medium– walking; It’s always a good idea to hike with at least another person and not to loose site of other hikers behind you. That’s how hikers get lost! The idea here is to spread out, but to stay together as a group. It’s also important to stop at the designated break points to regroup.
There’s plenty of parking int he surrounding neighborhood.
There’s a nice 4 mile loop trail, with a series of rises and drops that should make this trail a minor challenge in a few spots.
This trail is great for training & is well maintained.
The scenery is plentiful during the spring when wild flowers are in bloom and the hills are carpeted with fresh vegetation.
Stay on the trail at all times as the area is protected by the Irvine Ranch Reserve.
The trail begins with a few rolling hills and a small stream crossing (may be dry in summer).
At 2.5 miles, the trail comes close to a housing development. At this point, the trail makes a left turn and some hill work.
The last ½ mile is a downhill walk back to your car on Avenida de Santiago (Street).
BEWARE OF: Rattlesnakes, tarantulas, ticks and poisonous foliage.
FACILITIES: No water or facilities are located at the trail head.
Bring plenty water, snacks, comfy walking/​hiking shoes, hat & sunscreen.
