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.

The best thing about Big Tree Park is... the big tree! Rightfully named, Big Tree Park boasts one of the largest Moreton Bay Figs south of Santa Barbara, planted in the late 1880s by Mr. Edgar J. Owens, a Glendora local. Today, the tree is almost 100 feet tall and has cables reinforcing it. There are no restrooms available at this park, and sometimes there are events like weddings here.

There are only two runways here, and this small airport is a hub for flight training schools, charter services, and recreational flying.
