We spend night 2 here on a backpacking trip. Glacier Basin campground has about 5 sites and a group site. There are some that are more private then others but we opted for #2 which is across from the group site for the views of the mountain. There are two bear canisters available for food storage. There is even an outdoor compost toilet a short hike away. No privacy what so ever and it was pretty nasty. The white river is nearby and is a great source for water. There was reports of a bear visiting the campground but all we saw were frogs, deer, and squirrels. The sites were nice and flat and had plenty of space for our two tents and four chairs.
We hiked in from 1st and 2nd Burroughs which was basically never ending switchbacks. The hike out on the glacier basin trail was nice and easy. Pretty views of Mt. Rainier and the surrounding peaks.
