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.

Really enjoyed the trails here. Parking is only $5, not bad at all. There are several different trails to chose from, although there are a few that are closed due to the fires. Amazing views, super clean restrooms, and friendly park rangers. Will definitely be coming back. There is just a lot of horse poop, but nothing you can't walk past.

Good hike everyone is very friendly out on the path. Lots bikers so be sure to keep way for them. All the various trails can get a little confusing. Overall a good local hike. Parking is 5 dollars.

$5 to park. Not bad. Comes with a detailed map!!! Love it! Currently, some of the trails are closed due to the recent fire but they are super clear about which trails are open. Even with some trails being closed there were still a ton of trail options! Also we saw a crawfish so that was cool!

Really fun with great views !
Nice trails for moderate - advanced people
For sure going back

I’d say it’s longer than the length advertised, parts of the trail are still closed but we were able to follow most of it. It’s a nice hike!

Easy trail, but pretty with all the flowers bloomed. Not too crowded if you go early but it looked like it was about to be as soon as we finished. My dog also seemed to enjoy it.

We couldn't actually find this trail. The guys up front were no help at all. Neither of them knew where the trail was. We eventually got a map from them. We started out on what we though was the Santiago Creek Trail but never actually found it. We ended up on Lone Pine Ridge Trail, which took us to a higher elevation and ended up being a "Moderate" instead of "easy" hike. It had some decent inclines. Very light traffic. Much of the park is still very charred. Very sad to see. I wish they had better signage.

Weekday 3-hour parking at Fred Barrera Park, immediately west of Anaheim Hills Elementary School. Trailhead is immediately behind the portable classrooms at the far east side of the school parking lot, almost to the street.

Mustards and flowers are returning in some areas. The hill west of the Old Weir Canyon Trail was solid mustard plants before the fire but still has a long way to go. Snakes and rodents are starting to return too. This has been one of my favorite trails for decades and still is.

Wildflowers and mice are returning well after the Canyon Fire. Saw two rattlers today, including a juvenile lying in the middle of the Anaheim Hills trail with a fresh mouse kill.

Our little pup had a wonderful time, as did we !!

Hiked with dog on 3/31/18. The effects of last October’s wildfire were devastating on the park and its many oak trees and other vegetation. But there is also much new greenery and growth. Saw many wild California poppies, maybe more than last year.

great views and birdwatching (woodpecker, hawk, multiple smaller birds). many signs of regrowth after the fires with saplings and wild flowers popping up.

great trail to frequent.
street parking.
some parts are burned and rebounding.
starting to green out for spring already as well in some parts.

Solid park with diverse landscapes that allow you to choose your level of difficulty.

This place is so beautiful. We came to so a short hike on 3/2/18 and it was awesome. Me and my dog were the only ones on the trail.

I will definitely return to this one since it is not too far from where I live and there are so many trails I didn't do on Sunday. There are many interlinking trails and we did the shorter trails that were closer to the creek since there were people in our group who don't do much hiking and wanted to take it easy on them. We did about 4 miles and there wasn't much incline. I will do some of the harder, longer trails next time.

Parking- we paid $5 since it was Sunday (weekdays are $3); there was a friendly worker at the gate who provides us with a map;
Trails- wide multi-use trails that are great for sharing with mountain bikes (there were many) and there was lots of clues on the trail that horses use these trails too but we didn't see anyone on horseback; i preferred the trails closer to the entrance where the round, concrete steps to cross the creek are.

We have gone here twice and it has been ok. We are in no rush to return. We have had no trouble finding parking on Hidden Canyon & E. Overlook Terrace. Both times we have taken the trail that heads to the NE and RT is about 3.7 miles. As you enter the trail head there are options to go south and we will need to check that out next time. There aren't amazing views or a cool destination to see at the end of this trail. The trail loops around and it is pretty close to homes at part. It is a decent option since it is not very far away. On one of our visits we came across a snake and a large tarantula just chilling on the trail.

I loved here! My son and my dog were leading the way. It’s peaceful and quiet and we got to see amazing views and clouds...

Good trail with lots of hill climbing. You are rewarded with some good views of the mountains and hills.

The OC Parks web site says this trail is now open. A few signs 2 miles in (northeastern most portion) say it is still closed, but that may be for people entering from that remote location and those signs simply have not yet been removed.

The trail is very stark and surreal after having been burned in the Canyon Fires. Only cactus and the largest trees and bushes survived, and the only wildlife are birds. Hopefully nature does its job and rejuvenates the wildflowers this spring. The rain from 2 weeks ago finally helped new grass sprouts everywhere, a uniform 2 to 3 inches. Weekly visits may be fun for my son to watch nature rebound and return.

Great place, easy trials for the kids from 3yrs and up.

had many trails to choose from. wish we would have come earlier to explore more.

good hiking trail easy to do just need to follow map as no signs
