Check out the Baxter website to reserve a shelter, and the easiest Trail to the top is the saddle Trail. Make sure to budget about 2 hours per mile and take a headlamp and set a turnaround time to make sure you come off the mountain before dark!
CHIMNEY POND CAMPGROUND!!! We didnt spend a lot of time here, unfortunately. While ascending and descending to Baxter Peak on the Saddle Ridge trail we stopped by here to rest and eat Lunch as well as get pics of Chimney Pond. The Ranger at The Ranger station was nice. Hope we get the chance to camp here here soon.
