Camping in Yosemite Valley: Sunnyside Campground (Camp 4) is a walk-in, first-come, first-served campground located across the road from Yosemite Lodge. Tent sites are $5/person. Because campground occupancy is generally low this time of year, sites will almost certainly be available, but be advised that you should be prepared for inclement winter weather.
Food and Dining
Coffee, tea, and snacks will be available before the meeting each day and during morning and afternoon breaks. No meals will be provided. Food and dining options include: the Food Court (a cafeteria-style food service), the Mountain Room Restaurant and Mountain Room Lounge at Yosemite Lodge at the Falls, DegnanÕs Cafe and Deli at Yosemite Village, and the Village Store in Yosemite Village, which offers basic grocery supplies. There is also a small convenience store adjacent to the Cliff/Falls Room.
