Memorial Weekend is the busiest weekend in America... just not in the Trinity Alps. 4 hours away from San Francisco, nobody seems to know about this area. There are a bunch a first-come first-serve campgrounds that were almost empty.. the whole weekend! We took our canoes down the river twice for a total of 33 miles. The first day we went from the Old Bridge put-in to our camp at Steel Bridge Campground, 11 miles. The 2nd day from Steel Bridge Campground to Junction City river access (across from Junction City Campground), 22 miles.
