There are only a few buildings in Buck Meadows proper and the Yosemite Ridge Resort is right on the main highway into Yosemite, so finding it won't be an issue. However, if you get to the Yosemite Westgate Lodge, you've gone just past it (assuming you're approaching Yosemite). You'll reach Buck Meadows about 10 miles (16 km) past Groveland; if you're approaching from Yosemite, you'll find it about 13 miles (21 km) outside the Big Oak Flat entrance.
