You can cycle down to the Ranger Station for free and there is a bike rack to leave your bike while you explore the area. If you're not up to cycling back up the hill towards Mammoth Lakes you can pay to ride the shuttle back up if there is room. Keep in mind that the road down is steep and narrow, uphill traffic has the right of way, and the 15 mph speed limits applies to bikes as well as motor vehicles.
