Hike to the ruins of the Echo Mountain Resort before heading up to panoramic views at Inspiration Point.
The trail switchbacks up the mountain before reaching the first historic marker, in 3 miles. These are the remains of the Mount Lowe Railroad, which brought customers to Echo Mountain Resort, also in ruins, nearby. Explore the historic sites, then head up Castle Canyon Trail.
A steep climb will bring you to Inspiration Point, where telescopes give views of the area. To head back down, take the shady Sam Merrill Trail.
For a shorter hike (5.6 mile), check out Echo Mountain Loop.
