Camping is easy at Georgetown Lake , with an abundant mix of private and public campgrounds in the area.
At Denton’s Point KOA (west two miles on S. Shore Rd., 406/563-6030), there’s a marina with a bar and restaurant.
Just up the road is Georgetown Lake KOA (406/563-3402), open all year.
Tent campers will prefer the Forest Service’s (406/859-3211, www.fs.fed.us/r1/b-d ) Lodgepole Campground (reservations available at 877/444-6777, www.recreation.gov , late May–late Sept., $10, $8.65 reservation fee) just across from Georgetown Lake.
Flint Creek Campground (May–Sept.) is a primitive Forest Service campground three miles west of Georgetown Lake just off Highway 1. Remember to bring drinking water, because there is no piped water.
Although most visitors here camp or stay in their family cabins, a couple of Georgetown Lake hotel-restaurant combinations offer good food plus access to the lake and nearby Discovery Basin  skiing.
The Seven Gables Resort (18 S. Hauser, 406/563-5052 or 800/472-6940, http://sevengablesmontana.com , $50 and up) is just off the main highway on the road to Discovery Basin and offers rooms (pets are allowed), a café, and a bar.
Another good bet is the Brown Derby (13902 Hwy. 1, 406/563-5788, $50), a nice little motel with a good restaurant across the highway a short ways from the lake.
