When summer comes head to the Tahoe area and there is plenty of mountain biking. Cisco Grove has great mountain biking. Stampede and Boca water. Your choice and they are only two hours from home.
Blue Lakes, Hope Valley off of SR 88 with lots of great mountain biking and hiking opportunities. Most is boondocking but you don't want commercial RV parks.
