Commercial Street crosses the Downie River close to where it meets the North Yuba River. The bridge itself is an interesting curiosity, and narrow!

Once a gold mining camp, Goodyears Bar is no longer the bustling town it once was, but it makes for a great destination on The North Yuba Trail from Downieville.

There are two parts to Big Boulder, the climb up and the downhill. The climb is loose and steep in places, but it's worth it. With incredible views of Sierra Butes, it's a great alternative to the classic Downieville Downhill.

Downieville maybe be known as a mountain biking town, but it's just lovely on a road bike. It is where the two rivers, the North Yuba and the Downie, meet. There are plenty of places to eat and drink in the town, as well as accommodation, if you are looking to stay a little longer.
