Glacier National Park Chat

Interested in best place to 'car' camp and favorite hikes in the area. Hiked Alderson -Carthew several years ago and eager to explore more of this area. WIll be there next week and will be day hiking only, but able to go 15- 20 miles if it's worth it!
Any recommendations on restaurants and inexpensive lodging also welcome! Thanks -

I LOVE MG Campground and generally spend 2/3's of my 2-3 week stays there....

Rising Sun and Two Medicine have very nice campgrounds as well....

Thanks for your response!
particularly interested in your 'some other fun' hikes - any you would recommend over another?
lee ridge/belly river loop and CM customs to Swiftcurrent well defined trails?
any suggestions for the Waterton part of the park?

Yes, they are all on well defined trails....

Swiftcurrent to Chief Mountain is awesome.....

I'd rate it slightly (but only slightly) higher than Lee Ridge/Belly River Loop.....
