    Reviewing West Fork:

    To get from the trails at Irvine Open Space to Laguna Coast Wilderness Park and/or Crystal Cove State Park, you're going to have to climb this fire road. A bit of a grind to the top, and just when you think you're about there, there's a last little bit that seems even steeper than anything else on West Fork, almost as if it does it on purpose!

    Wow. I don't whats been wrong with me. I've seen/passed by this trail on numerous occasions. Its taken me about 2 years to check it out, but I'm glad I finally did. There is a trail head at Bommer Vista Point which is at 340 Summit Park Drive in Irvine, CA. There is a very small parking lot - 6 spaces (1 for disabled), along with restrooms and a water fountain. For the first 3/4 mile or so, the trail follows the ridge and the edge of a housing tract. But soon there is a short climb as you crest the hill, and then after that the downhill begins. Basically, the trails winds down the side of the hill into a canyon, with numerous switchbacks. There are some slightly rocky sections, as well as a couple of tight turns - with some exposure/drop-off - that will keep your attention, but for the most part, you can swoop down, blast through the turns, then enjoy a straight run before another turn. Horses are not allowed on this trail, so you don't have to worry about them - but there are usually other trail users - walkers/hikers, trail runners, so please slow down and be considerate. The trail ends when you reach the bottom, you can either climb out by going up West Fork (www.singletracks.com/bike-trails/west-fork-.html) back to Ridge Park or continue on via Bommer Pass & Bommer Meadow to Shady Canyon etc. I'll definitely be riding this trail again!

    Reviewing Bommer Pass:

    This is a steep fire road that can be used to get from Shady Canyon up to Bommer Ridge and the El Moro trails.

    Reviewing Bommer Meadow:

    As its listed on many (trail) maps, "Bommer Canyon Road" itself, is not usually accessible - unless there are docent led events. Instead, you will need to take 3 different trails (which link), to cover the same amount of distance. The northern end of the trail(s) is Bommer Meadow, which begins at the Bommer Canyon trailhead. There is a small parking area here, along with rest rooms. The "middle" trail is "Bommer Pass" (http://www.singletracks.com/bike-trails/bommer-pass.html) and finally, "West Fork" (http://www.singletracks.com/bike-trails/west-fork-.html). Be aware that the Irvine Police Dept regularly patrols Bommer Canyon Road and if they catch you accessing, this or any of the other off-limit trails, you will get a ticket/fine...

    Reviewing Quail Hill Loop:

    Very easy short (multi use) loop. Lower part runs near the 405 fwy. Probably not somewhere you'll make as a priority destination, especially with Laguna Coast Wilderness park very close by. But can be nice after its rained and everywhere is green.
