West Ridge and East Ridge Trail is a 8 mile moderately trafficked loop trail located near Oakland, California that features beautiful wild flowers and is rated as moderate. The trail is primarily used for hiking, walking, nature trips, and birding and is accessible year-round.
Redwood Regional Park offers a cool micro-climate in hot weather. The creek running through the park is where specimens of rainbow trout were used to first describe the species. This hike starts by the creek and climbs up to the West Ridge, where you will have views of both San Francisco Bay and Mt. Diablo.
It's a pretty wide trail that's well maintained and resembles an access road for most of it, so not so much a hike as it is a great run or bike path. The lush greens, soaring trees and glimpses of views make it well worth it.
One of my favorite loops that's pretty simple
Trail as described starts at Canyon Meadow parking lot. Follow the paved path and take Bridle Trail to your left (stay left). This leads to West Ridge which is a pretty dramatic climb for a bit. Once you reach the ridgeline it levels off. Continue on West Ridge until Madrone (you can split off to Peak Trail if you want to catch the summit and come back, but it adds to the trail and we skipped it). Take Madrone down to French (go right) and then to Mill (it's a left) and then Mill back to the stream trail which will lead you back to where you started.
West Ridge was a little crowded (many trails head into it) and you have to keep an eye out for bikers, especially when ascending as they descend really fast. Stay right! But it was fun and Madrone/French/Mill are less crowded.
