August 25, 2025, Mueller Tunnel

Short tunnel on the eastern slope below San Gabriel Peak, part of the old Mt Lowe Motorway, that was never paved. The tunnel is very short, so you don't have to worry about bringing light. The road continues to the trailhead half a mile uphill.

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.
