Nice bike path. not much roads to cross. some are hilly but doable for newbies. It's our first time and we had a good time. just some areas are with a lot of homeless people, esp. the tunnels.

Mount Baldy Village & ski resort towers above the San Gabriel Valley & Los Angeles suburbs and is a lovely alpine community with a wonderful restaurant and a pub. It's a great place to stop, take in the incredible scenery, and refuel during your ride.

Halfway up the Highway 39 & Dawson Saddle climb, the Upper Bear Creek Trailhead is a good place to stop for a break if you need to catch your breath. While the trail itself is not suitable for road bikes, the trailhead has picnic tables and restrooms, so it is a good spot for a snack and quick breather.

Great view of the Puddingstone Reservoir, a 250-acre man-made body of water. There is a road that runs along the perimeter of the reservoir and there is a spot to pull off the road to get a close up view of the water.
