Super Bloom in effect, go while it's green. Great trail running!

One of the best family trails in OC, esp right now after all the rain, everything is SO green!

This trail is very nice. Quiet, not busy in November (though very dry, as with most of our poor state). Has several very steep and narrow areas so my sister with a double bob stroller did struggle. Good for kids but definitely tiring for younger ones.

Docked a star for banning dogs. This would be an excellent dog trail. This park has posted mountain lion warnings and has somewhat isolated areas, and the idea of walkers not being able to take their dogs for security purposes against man and beast is super lame.

Great for a quick trail close to home. Gives you the feeling of being outside in open space which is hard to find in Southern California. This time of year (September) it’s definitely very dry. But still beautiful. Nice hills but nothing too hard. Kid friendly.

This is a pleasant hike with some gentle ups and downs and some really nice views of rolling, grassy meadows.

Been on this trail numerous times. It is beautiful in the Spring.

This is a great trail with hills flats and sand. If you are trail running you get alittle of everything and good for hill repeats. The hills have no shade but the flats of the trail do. Good for kids and well marked.

Mule deer trail and horned toad trail are pretty neat. The location is extremely convenient for people who live in coto de caza.

This is a great little trail. The climb in elevation isn't to bad, and the view is most certainly worth it. Watch out for little frogs on the path and decent sized rattle snakes. I almost stepped on one, I wasn't watching the path and watching birds instead. Beautiful trail!!!

Lovely trail, but nearly stepped on a baby rattlesnake, so keep your eyes out.
Thought it would have been too cold for them, but someone else had seen one too so they're around, please be careful.

Great for kids, I've hiked this several times with my kids (two girls ages 3 and 4). Mule Deer are regularly resting in the shade and after a good rain you can hear frogs croaking in Dry Pond. Beware of rattlesnakes! We encountered the first Southern Pacific Rattlesnake of the season on Mule Deer Trail yesterday (2/1/17). They like to hide in the cacti next to the trail, so keep your eyes peeled.

Nice trails for local residents. Not challenging for serious hikers. Keeps me in shape during the week. Used to see deer but they are rare now.

It was a easy walk. Not really a hike. Had some hills to make it more or an exercise.

Upon entering Mule Deer Trail we saw about 7 or 8 deer come out of the woods onto the prairie to graze. There were at least two baby deer. Very cool. Plenty rattlesnake noises along the trail. Spiders and beetles. Woodpeckers and Hawks.

I just hiked here for the first time following knee surgery, although I have hiked all of the trails before.
A good easy place to start!

Excellent. Always about a dozen mule deer around.
