I picked up my GFC almost a year ago but only had one day before I had to head home. If you can plan time to explore this area I highly recommend it. That’s why I came back about a month ago and spent 12 days biking, hiking, fishing, kayaking, Sup, and off-roading.
I don’t like campgrounds so I spent most of my time exploring random dirt roads which are numerous around this area. I did stay at one campground called Fairy Lake which was nice… Amazing views, great hiking with a beautiful lake. Also spent one night at a hotel in Bozeman to clean up and go out to a restaurant where we got to eat inside! That is not allowed in Cali righ now… Went to Mountains walking Brewery. Good food and beer.
In close proximity to Ferry lake off Highway 86 is an area called Battle Ridge. I drove out some dirt roads here and camped.
There’s a good bike ride called The Wall of Death near Bozeman. Known as Bozeman Creek Trailhead off of sourdough canyon Road. I did this trail and then drove way up this road and found a random spot to camp
I also spent several days camping on dirt roads off hwy 191 near Big Sky. If you’re into downhill mountain biking Big Sky Resort is amazing! I spent three days biking there and would go and camp within 30 minutes off of some of the dirt roads below. There’s also really good fishing and kayaking along the Gallatin river.
Portal Creek Rd, Moose Creek Rd, and Swan Creek Rd.
