This is a great trail without the crowds. I took East Canyon to the top where it merges with the Weldon Canyon trail. 2.7 miles. Go .4 miles further to where the trail is fenced off. Here there is a sign for the Mission Point Trail. It's another 1.5 miles to Mission Point, on mostly level terrain. It adds 3 miles RT, but it's an easy 3 miles. I highly recommend taking this all the way to Mission Point, as it's more challenging the hiking up from O Melvany park, and the views are incredible.

Great place to run!
I've been running up East Canyon for about a year. Trails are maintained regularly. Haven't had any issues with ticks or rattlers. Shaded for a good part of the hike. Lots of trees, bushes, and flowers. What I love the most about this trail are the views from the top. You can see the SCV and the SFV. On clear days, you can even see down town Los Angeles. Not many people know about this trail it seems, because chances are that you'll maybe encounter one or two people on most days. Beats the overcrowded trail at Towsley Canyon, in my opinion.
Nice, mostly paved trail near my home. I've hiked and biked this several times. My dogs love it, too. Interesting history including several old buildings and the site of the first commercial oil well in California. Consider adding to your hike (and save a few dollars on parking) by parking outside the park. Watch for rattlesnakes and coyotes...I have encountered both in this area.
