There is the chalet and there are the campsites. We stayed in the campsites our last night hiking through the gunsight pass exiting Lake McDonald. There is a mountain goat with blunted horns (who we named Earl) that frequented the site while we were cooking, setting up our tent, and again in the morning. Watch out if your underwear is hanging to dry. Keep it high enough so Earl can't reach it! The hike to this site is amazing. After our 4 night trip through the pass we were pleasantly surprised by the Chalet. They offer lemonade, hot coco and coffee free of charge to anyone until about 10:30pm. The chalet also offers hot breakfast and dinner, but you need to stop in and make a reservation before hand so they know how much food to pack in. Our last night in GNP we hit the Chalet, got some coco, and made a breakfast reservation. Well worth it. The campsites are nice. There is one that is literally overlooking a huge cliff with a stone ledge. If you want a great trip start at Jackson Glacier Overlook and end at Lake McDonald, with a stop at Sperry for your last night!
