June 29, 2025, Ye Alpine Tavern ruins

For a ride with history and views, check out the Ye Alpine Tavern ruins in the San Gabriel Mountains. Once a popular mountain resort, it burned down in 1936 and was later demolished, but you can still spot the stone fireplace, foundation, and water tank.

Andrea Wilson Triangle is a small protected area along Chaney Trail in Altadena. Though not a developed trail, it’s part of a larger effort to preserve open space and wildlife habitat in the foothills near Angeles National Forest.

Tight, rocky, and exposed—this one’s a classic if you like your rides technical. The climb is tough, but the views are worth it. Watch for hikers, take the switchbacks, and ride early if you want to avoid the crowds. Not for beginners, but a fun challenge if you're up for it.

The Gabrielino Trail spans 28.8 miles in the heart of Angeles National Forest, featuring a mix of well-known and secluded areas. This scenic route is perfect for running and boasts historical importance as well. In 1970, it became the first National Recreation Trail (NRT) in the country, honored for its regional representation, support of a diverse community, and recognition as one of America's finest trails.

A site with spectacular views over Los Angeles County. Additionally, beneath the pavilion, you'll find various sighting tubes, each pointing to a different location, such as Redondo Beach, Catalina Island, Hollywood, etc.

If you are looking for a historical and scenic trail run in the San Gabriel Mountains, you might want to check out the Ye Alpine Tavern ruins. This was once a popular mountain resort that welcomed over three million visitors in its forty-one years of operation. It was destroyed by fire in 1936 and demolished by the U.S. Forest Service in 1959. You can still see some remnants of the resort, such as the stone fireplace, the foundation, and the water tank.

A series of disasters has eroded the properties in this area. In 1900, a kitchen fire destroyed the main house, and in 1905, another fire consumed the remaining structures. From 1909 to 1938, a combination of flooding, wind storms, and additional fires destroyed the rest. Here, you can now observe the ruins of the observatory and enjoy the beautiful view from this point.
