Baxter State Park encompasses 209,501 acres of wilderness in northern Maine, anchored by Mount Katahdin, the highest point in the state at 5,267 feet. The mountain is the northern terminus of the Appalachian Trail, the 2,190-mile footpath stretching from Springer Mountain, Georgia. Each year, roughly 3,000 thru-hikers complete their journey here, touching the Katahdin summit sign at Baxter Peak after months on trail. The park was gifted to the state by former Governor Percival Baxter beginning in the 1930s with the explicit mandate to remain forever wild — no cell service, no ATMs, and strictly limited visitor numbers are the result. Day hikers and backpackers must book campsites or Katahdin summit reservations through the Baxter State Park reservation system, which opens in January and fills for peak summer dates within hours. The most popular route up Katahdin is the Hunt Trail (5.2 miles one-way, gaining 4,182 feet), which follows the Appalachian Trail from Katahdin Stream Campground. The Knife Edge — a narrow arête ridge connecting Baxter Peak to Pamola Peak — is one of the most spectacular and exposed hiking routes in the eastern United States, requiring sure footing and a strong comfort with exposed heights. Beyond Katahdin, the park contains 46 mountain peaks, 18 campgrounds, 215 miles of trails, ponds teeming with loons, and abundant wildlife including moose and black bear. Day-use vehicle reservations are required and capacity is strictly capped — summer weekend reservations sell out months in advance.

Highlights
- Mount Katahdin summit (5,267 ft) — Maine's highest peak and the northern terminus of the Appalachian Trail
- The Knife Edge, a narrow arête ridge connecting Baxter Peak to Pamola Peak with dramatic exposed drops on both sides
- 209,500 acres of forever-wild wilderness with no commercial development, cell service, or roads beyond permit access
- Abundant moose sightings along Roaring Brook Road and near Sandy Stream Pond at dawn
- Katahdin Stream Campground — the traditional final night camp for Appalachian Trail thru-hikers
Tips for visiting
- Reserve campsites and summit-day permits through the Baxter State Park Authority website in January for summer dates
- Start the Katahdin summit hike by 6 a.m. to allow time for safe descent before afternoon thunderstorms
- Bring sturdy hiking boots with ankle support — upper trails involve talus and exposed ledge
- Carry all food in bear-proof containers; black bears are active around the park's campgrounds
- The Knife Edge is best avoided in wet or windy conditions — treat it as a fair-weather-only route
When to visit
July through September provides the best trail conditions for Katahdin. May and June bring mud season making many trails impassable. For moose viewing without the summit hike, May and early June at Sandy Stream Pond and Roaring Brook Road at dawn are prime.

Frequently asked questions
How difficult is the hike up Mount Katahdin?
The Hunt Trail (Appalachian Trail route) is strenuous — a 10.4-mile round-trip with 4,182 feet of elevation gain on steep, rocky terrain. Most hikers need 8 to 10 hours. It is not appropriate for beginners or visitors without prior mountain hiking experience.
Do visitors need reservations for Baxter State Park?
Yes. Day-use vehicle reservations and campsite reservations are both required and are booked through baxterstateparkauthority.com. Summer weekend dates sell out months in advance; off-peak weekdays have better availability.
Is Baxter State Park suitable for families with young children?
The park has easier trails around its ponds suitable for families — Sandy Stream Pond (0.5 mi, easy) offers reliable moose sightings and is appropriate for all ages. Katahdin itself is too demanding for young children.
