The Echo Mountain hike packs a lot of bang for the buck. You’ll hike up the Sam Merrill Trail, which follows the old Mt Lowe railway route up to Echo Mountain, where you can see the old ruins of the Echo Mountain mountain resort. USA Today included the Echo Mountain hike as one of the “10 Great North American Hikes” and Sunset Magazine called it one of the top 45 hikes in the west. The hike is easy to follow, has an interesting history, offers great views, is a good workout, and is close to LA. Overall it’s a win.
