Yosemite Pines is not on Highway 120, the route into Yosemite, but a short ways off it on Old Highway 120, at the location of the blue balloon on the above map. Shortly after passing through Groveland en route to Yosemite you'll see a sign for Old Highway 120; take it and you'll reach the Pines Resort in about a mile. If you miss the turn onto Old Highway 120, there'll be another in a mile or so; this second turnoff will have a sign advertising the presence of the resort. From this turn, it's also a short drive - half a mile or so - to the resort.
