 The Merced River and its tributaries are a popular recreational area in part because of Yosemite National Park. There are many activities within the watershed, including boating, fishing, camping and hiking. Whitewater rafting is permitted throughout Merced River Canyon from the downstream half of Yosemite Valley to the entrance of Lake McClure. The most difficult rapids in this segment rate Class III and Class IV, mostly upstream of El Portal. There is also boating on Lake McClure. Camping throughout the upper Merced watershed is generally only permitted in designated campgrounds. Campgrounds along the Merced River and its tributaries include ones at Railroad Flat, McCabe Flat, Willow Placer, Merced Lake, Vogelsang Lake, Sunrise Creek, May Lake, Bridalveil Creek, and a ski hut at Ostrander Lake, the source of Bridalveil Creek.
