A hidden jewel of a trail with a (+4000') elevation gain in 6.8 miles. Walkable and bikeable. You must come prepared for sun, shade, rain or snow. Bring water, can be done as a long day hike or an overnighter. Can also be a backdoor to Mt Wilson. This trail overlooks the Grand Canyon of the San Gaberials and offers... More

I started this hike at Sam Merrill Trail off of Loma Alta Drive. The hike is about 5.8 Miles round trip to the top of Mount Lowe Railway with about 1400 ft elevation change . This hike has a nice steady incline all the way up so bring at least a liter bottle of water and a snack(there are some... More

If you live in the Altadena area, this trail is a must. Also known as The Lower Sam Merrill Trail, it's a beautifully graded, solidly reinforced and, for the last 10 years, rigorously maintained. Good thing. Because of the local geology is fractured composed of fractured rock, the trails of the San Gabriels require constant maintenance, If you compare the... More

The Sam Merrill Trail is easy to find...go north on Lake Avenue from Pasadena through Altadena until Lake stops. You are at the trail head. This is a pretty easy walk on a hard packed trail that gets you to the top of Mount Lowe. there was a hotel, tennis courts, etc. and an electric railway that ran until the... More

This is an easy hike for most people, with a great reward at the top... great views of the LA basin and the ruins of a hotel complex that was here over 100 years ago. Bring water and don't go in the middle of a hot day, and you will have a good time.

We are fortunate to live close to this trailhead, which takes hikers to the historic ruins of an old hotel at Echo Mountain and remains of the Mt. Lowe Railway. Yes, you should be a hiker in fairly good shape (it's just shy of 3 miles each way), but I would classify it as moderately difficult. From Echo Mountain, you... More

This is simply a hard trail, though very popular. It is the 405 of hikes. Get there early in order to park. Go in a group to improve your parking chances. The trail itself has little to recommend it. It is not in itself pretty. It is in the sun most of the day (again, get there early). The views... More

You will be hiking up. And up, and up! You should be in good shape and packing water with you. I have never made it all the way up. My guess would be 4 or 5 hours. I go for one or two hours and drink 4 bottles of water. I have a grand time doing just that.

Easy to moderate hike up the hill...If you're not too outa shape. Simple hike up the hill if you hike a bit. Round trip is probably 5-6 miles. I've always continued on up to Inspiration Point (doubles the distance but way fun) Train/tram history is amazing. Gets crowded on the weekends but weekdays are great. El Patron Restaurant is just...
