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.
This is a great trail. Lots of different views and grades which make it good for a never-boring walk. The breeze makes all the difference and keeps it cool on warm days. I've seen Whitetail rabbits lizards a road runner and heard a woodpecker. I've only seen one snake and that was a garden snake. The mountain bikers love the trail and there are plenty of them so you just need to be aware turning corners. In early spring there is Sage growing along the trail and plenty of Rosemary. There is a shortcut if you don't want to do the whole loop, you can turn at Deerweed Trail which cuts the loop by about half.
I really enjoyed this trail. It is not flat, and I never felt like the uphill parts were long or arduous. Saw some lizards and heard a lot of rattling in the shrubs. There was a nice cool breeze today that felt good when walking on the sunny ridge. There were a fair amount of other hikers with and without dogs, as well as a lot of mountain bikers (so keep your eyes and ears open for them!). I'll definitely be back here to explore the other trails in the area. It took me about an hour and 15 minutes to complete this trail.
The trail was beautiful, plus it's tucked back so it makes you feel like your somewhere else. The hike is relatively easy, but it does have a few steep hills. We took our dogs which was what made it that much more enjoyable! Highly recommend this hike.

My nine year old and I just started hiking and we loved it. He could have keeled going but I was feeling he burn. Definitely coming back!!
