Early summer weather in Lake Tahoe can be a bit unpredictable. My tent was put to a heavy rain test and survived. Fallen leaf lake is just off the 89. The campground is clean and spacious. There’s coin op shower in the area. It’s about a 1/4 mile walk to Fallen Leaf lake. The water in early June is still cold but good to dip in after a long hike/bike to recover the muscles.
