Experience the ruggedness of the glacier-formed Crazy Mountains from a spacious site in Halfmoon Campground. Nestled along Big Timber Creek, the scenery is awesome enough in itself. But add hiking and horseback trails, nearby waterfalls, fishing, and opportunities to sight mountain goats over your morning coffee, and you’ve got a whole lotta of day on your plate. Speaking of which, the area offers picnicking sites adjoining the campground that are available for anyone to use. You can never have your fill of the Crazies, there’s always room for s’more!

The campsite itself is breathtaking! The sites are well spaced and each one has amazing views of the towering peaks surrounding the campground. We pretty much had the grounds to ourselves mid-week, but I hear it can get busy on the weekends. There is a rewarding, short hike to Big Timber falls from the grounds, and also further hikes to alpine lakes. We tried hiking to the lakes but in June, there was still too much snow on the ground and we lost the trail. Overall, this is one of my favorite camping spots in Montana. It is a real gem! Quiet, beautiful, and in the heart of the Crazy Mountains....a must see! (sidenote: dogs are allowed on-leash in the campground)

Trailhead to Big Timber Falls from the campground. Big Timber Falls- a short hike from the campground. Wildlife in the campground. Our campsite spot.

Halfmoon campground is epic. Very off the beaten path, you have to drive through much farmland, even passing through a private cow gate to get there. Just be sure to close it behind you. The campground was very quiet, which is understandable as it is quite a drive. Very well kept though and the views and sounds were magnificent.

Campground is VERY off the beaten path. Ridge lines all aroundThe creek that runs by is always audible.
