Our favorite campground in Glacier.
Positives:
Scenery is the most dramatic
Wildlife - lots of it, seems more so than other areas
Lakes, rivers
Negatives:
Lots of other people know the positives

You are literally seconds from a variety of fantastic trailheads. There's also a camp sotre with a place that serves meals. You can do boat rides on Swiftcurrent Lake, and actually a short hike from that to another boat ride on Lake Josephine. I think the camping sites are spacious, with good privacy. We like the ones along the creek. The restrooms are in good condition. Everything is within quick walking distance including the camp store and restaurant.
Big thumbs up for Many Glacier!
