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.
