We took the kids camping along Rock Creek, on the eastern side of the Sierra, near Bishop. The campground is in a narrow valley with a creek running through it (the creek is the main attraction). Kade and Sierra loved crossing back and forth over it on logs- Terra generally preferred to swim, though she is surprisingly agile on a log (only fell in once).
The route to/from Bishop goes over Tioga Pass, in Yosemite National Park. Laura’s mom and friend Esther accompanied us on this part. Sierra and Kade both hiked up to the base of Bridalveil falls- an interesting scramble over well polished rocks.
