Hahamongna Watershed Park

It’s not one of my favorite parks but it’s very useful for the Girl Scouts. Every summer, the Girl Scouts use the park for a week. They explore, play water games, and cook. There are several tables and benches. There is some parking near the tables, but it’s very dusty. When you drive to that area, the dust really flies! Some areas have grass.
Good area to walk your dog, but please pick up after your dog. It smelled pretty bad near one of the tables. I would hate to sit there!

I was looking for Gabrielino Trail and took the wrong way. Instead of going straight, I went down a rocky trail (if you’re new, wear leggings or pants, especially if you are clumsy) and wondered why the area looked different than the pictures posted by the Unilocal community. As soon as I found a posting about Devil’s Gate Dam I realized that I took the wrong way.
If you want an introduction to hiking I recommend this route. There is a paved road and plenty of soft ground, which is good for your knees. The area is good for horseback riding, cycling and trail running. Got dogs? They can walk here but some people don’t pick up after their dogs. Watch out for horse bombs; I had a horse fart on me and it was not pleasant. If you are an experienced hiker, you’re not going to get a tough workout. Bring insect repellent.
The parking isn’t great and some people find creative ways to park (shhh). There are plans to construct a gas pipeline through JPL and the park; this makes me think. But if you’re not planning to walk through craggy areas and/​or looking for an alternative to Eaton Canyon then walk here. If you’re used to trails like Descanso Trail or La Tuna Canyon then you’re not getting a huge cardio workout.

I want to try hiking here. I guess this is where you park your car if you want to hike and explore the damn area and that area they call «devils’ gate».

Nice park but lots of trees and dry lake bed that make the whole park hard to utilize. It is a nice park to take a bike ride or bring a pet. I rode my bike on the back trails through it and when I went a few years ago there was water in the back in a stream that went all the way up to angels crest highway. Anyway it is a fun place to spend an afternoon

My cross country team runs in Hahamunga park. There are a lot of great trails and I always look forward to training here. Also it’s a great place to take your dog.

Nice place to take a walk solo, with the pup, or in a group. It’s a large park with tons of parking, a small lake/​pond, disc golf course and a few other basic amenities. I find myself here mostly evening during the week, walking with the pup or getting in a quick run when I feel like a change of scenery rather than my usual route around the rose bowl. Connor my pup, seems to do better at this park than the loop at the rose bowl. The dirt/​grass combo is easier on both our limbs.
The disc golf course could use some help, and if I had it my way the park would stay open all day and all night too. It’s a safe neighborhood. Also I get a lot of negative comments about my dog being on the trails, so maybe a designated area fenced off for dogs would be a lovely addition. Considering the lack of decent dog parks in the area I’m sure the residents would oppose this less than the idea of dogs using lawns for restroom purposes, etc. It would also be rad if they added a few strategically placed solar lights for twilight walks or the last few holes on the front and back courts.
All and all a lovely park, I’m glad there is a place so close to home and in the middle of an urban area that exemplifies what the area looked liked naturally. It makes perfect sense that teachers from the surrounding schools use the land to teach the younger generations about ecology, geology, et al.

I have so many fond memories of making forts in the brush and counting birds behind the dam after a big rain. It’s really a treasure to have actual wilderness so close to your small town. Hahamongna Watershed Park is also home to the first Frisbee Golf course and JPL.

Fun place to take the dogs. Lots of space to roam and explore! I hear there’s water in the «rainy» season. Can’t wait to see it.
There are typically no other people when I go which is nice, I love having space to myself to explore with my dog.
It’s November and still a bit dry right now, watch out for foxtails if you’re bringing your pup.

Want to hear babbling streams? Just keep walking. Hahamongna itself is dry, not simply because of drought. Though it has certainly not rained to refill it, the watershed behind Devil’s Gate Dan was purposefully and drastically drained in spring of 2014. There is some cleanup and clean out work being done. All this to say that, despite the drought, there is lovely running water in the streams you can enjoy as you enter Angeles National Forest via The Gabrielino Trail north out of Hahamongna. You’ll be glad you traversed this trail and escaped the city as well as the drought. Inexplicable beauty and aquifer. It’s an easy hike.

Hahamongna Park is a great place for many reasons:
They run multiple after-​school and summer programs/​camps for kids
They offer the frisbee courses thats all the rage
They have tons of hiking and horse trails
Unfortunately, due to the weather and lack of rain, the water shed is dry. Hopefully we can get a lil more rain so we can fill the water back up…

Terrain: check
Great Views: check
Decent length holes: check
I stumbled upon this park after a serious half hour of Unilocal research. A few friends and I were itching to blast a few discs off one Saturday afternoon and this park definitely fit the bill.
The park is interesting enough and provides enough challenges to keep things fun and fresh but not overwhelming.
Round some buddies up, grab a disc from the liquor store right down the street, and let the good times fly (no pun intended)

This short review is for the disc golf course. We stopped by Saturday afternoon to explore and throw a few Frisbees. This was a first for my son and I but lucky for us we were with a seasoned vet ;)
My son absolutely loved it! Definitely seems like a guys pastime as there were certainly more men on the course than women but this can be a fun date spot and pastime for you outdoor lovers. Sure, it won’t take bocce balls place in my heart but fun can be had once I practice a bit more.
It was a very spontaneous visit and we weren’t exactly in proper footwear — flip flops! I’ll be back in tennis shoes, with a good supply of water and a small snack for a warm afternoon to practice.
May be more enjoyable in the cooler months.

Nice park situated around JPL. You’ll leave feeling smarter than when you came lol. Jogged along the trail on the east side. Went out about 2 miles to a small stream crossing and came back. Started at a little parking lot off Windsor. Has a water fountain to rehydrate. Great sunset view too!

We had a great time here… We biked it/​hiked it. Since we are no experts on bike riding we took the easy trail. Going up was a bit challenging but coming down was awesome!!! I would highly recommend taking safety gear such as helmet, shin guards, elbow pads, ect. It took us some time and a little bit of luck to find this park. I looked every where for directions but the address I guess is a mystery. This place is off the 210 exit Arroyo Secco/​Windsor head east away from the rose bowl and youll end up right at it… Windsor st and Ventura ave

I had to write a little update concerning the Park Rangers I thought I saw. Yesterday I walked up to a big group in their green uniforms and they told me they were Animal Control and not Park Rangers. I didn’t want to give anyone a false sense of security. The Animal Control officers said that rattlesnakes were spotted near the restroom. Be really careful.

I would have never thought this park was here unless I had looked it up. nice place to venture around, or just sit and relax

I came here for frisbee golf and it was awesome! It was busy that weekend as the huge tournament was the following weekend and people were practicing. It was clean, a good view, and lotsa parking. The courses were hard, but not too hard for a beginner like me. The challenge level was just right. Everyone playing is very friendly and nice. Some people brought their pets, kids, or babies in athletic strollers. I would definitely come here again for frisbee golf.

Writing this from the point of view of a soccer player. The games we have that are held here are not something to look forward to. So many holes in the grass, it’s a definite recipe for all kinds of injuries and unpredictable ball direction and speed changes. It is at least a pretty large space, enough for two simultaneous 7-​v-​7 games. The parking is also incredibly limited, but at least u can park in the dirt overflow parking area.
The map here shows the park as being somewhere totally off. Entrance is on Foothill and Oak Grove, but by Montrose. Your better off googling La Cañada High School, as it’s right across the street. Upon entering the park, u drive down a sorta windy road until u get to the park area. There is often ultimate frisbee players there. Not a shabby park, but not the best place if u are looking to play games on a flat grass field.

The location of this park does begin at Foothill Blvd. & Oak Grove, but you have to make a couple of turns and along a narrow trail to get into the park.
There is a picnic area with grill — great for summer BBQs, as well as a partially covered trail. I appreciate that they have doggy bags along the trail, so no excuses for not picking up after your pooch! :) They also have a dog/​human water fountain, so very convenient!

Amazing Park
The Rose Bowl Half Marathon route came through the Hahamongna Park on Sunday, January 22, and it was amazing to run through the park. There were so many beautiful parts, but as it was a race, I ran right through the trails.
I will definitley be back, and it’s easy to get to if you park at the Rose Bowl and walk, run, hike, jog up the trail, go up the hill and under the tunnel of the 210, and VIOLA! You’re there!
