Mendenhall Campground is right on Mendenhall Lake and keeps you away from the crowds that come into the ranger station and visitor center. Best way to avoid the cruise ship crowds is to go early or late. Photo point trail and Nugget Falls trail are a must and have the heaviest foot traffic from 10am to 2pm. There's way more seclusion on the East Glacier trail and the Trail of time which are both longer. Half way up nugget falls trails there are a few cut through's to the lake where you can find nice private beaches.
