In 2008, the 210 acre Weir Canyon Wilderness Park was incorporated into Santiago Oaks. The annexation created a trail system that spans from Irvine Regional Park through Santiago Oaks to Weir Canyon in East Anaheim Hills.

Muy buen lugar para caminar y hacer senderismo me encanta lo recomiendo ampliamente. para los qué se quejan que no hay sombra les recomiendo ir a las 7 a.m. no se van a repetir.

Great selection of trails (all sign marked with difficulty ratings). Took a few ‘difficult’ detours from my initial ‘moderate’ routing. Some pretty steep and requiring decent balance and traction but nothing crazy. Just enough to get you puffing before it levels out again. Dig this park. Paid parking entry ($3 weekday, $5 weekend).

Came here on New Years with my family and again this last Saturday. Always a fun hike with good scenery. Some trails are challenging, others not so much. Good for all ages.

Nice hike. Good inclines. Listed difficult not intermediate as the post says.

Jan 2019: nice trail. People out on a Sunday but not too crowded. Horses, joggers, people with kids and dogs. Good 2 mi loop for kids (6, 8 yr old no problem) you can really customize this trail by adding on or taking short cuts. Fun historical element for kids with the history of the trees in the canyon and the old dam. Highly recommend for kids.

This trail was beautiful. Not overgrown or muddy. I did not give a 5 star only because the bikers. They fly by you without being very nice and we had a dog a man almost hit going really fast. If they had bells we would have been more prepared but we hardly saw them at times

Easy including dam, stepping stones, and creeks.

The hike was beautiful but definitely more so for mountain bikers. I relied heavily on my maps to be able to stay on the route so I didn't get to enjoy as much as I would've liked. There were a few sketchy patches that I wish I would've worn my legit hiking boots for, but I'm also very accident prone. I don't think I'd even attempt to hike during the weekend for fear of getting mowed down by bikers.

Great trails all around! Just watch out for bikers cause their is a good bunch of them here

Best conditions ever

This is a good workout with excellent views at the top of the ridge, but there were dozens of mountain bikers that kind of killed the quiet. The trail was wide and dusty. I can imagine it being unbearably hot in the summer, but for an overcast winter morning it was cool enough.

lots of mountain bikers but a good hike!

most of the trail is super nice and pretty with only the first half full of invasive plants and close to the housing, once you get back into the canyons and ridges it’s gorgeous! some of the trails are definitely discontinued so keep an eye out for that. dog friendly and watch out for mountain bikers

This is definitely a dog friendly trail. They have trash cans and poop bags at the start. There are mountain bikers on this trail as well. It’s a nice walk with lots of birds and good scenery. It costs $5 to park on the weekend.

First time here and it was awesome! I'll definitely be coming back for some trail runs and if I ever get into mountain biking. (Pro's): -Tons of well maintained trails everywhere. -Lots of single track and double track. -Some pretty cool views. -Great hills for hiking, trail running, or mountain biking. (Con's): -No shade. -Bugs can get annoying. -Had to pay for parking ($3). -Not a great summer location due to heat and lack of shade. Overall this place is great! One of my new favorite places around! Bring a hat and some water if you plan to go 5-6 miles.
