There's a window of opportunity each spring when some of the roads have been mostly plowed out but they aren't open for cars yet but they ARE open for bikes. No cars, great roads, lots of snow, scenery and the occasional wildlife-obstacle.
Four of us rode from Mammoth to Obsidian Cliff and back on April 12 - 20ish miles with a CRUISIN' downhill at the end. The road from Mammoth over to West, over to Canyon and down to Old Faithful opens to cars on the 18th.
