Planning tips
- Most thru-hikers start northbound from Georgia between late February and April. Consider a quieter start date or a southbound or flip-flop hike.
- Register your thru-hike start date with the Appalachian Trail Conservancy (it’s voluntary) to help spread hikers out.
- Baxter State Park, home of Katahdin, has its own rules and asks long-distance hikers to get a permit card. Check before you go.
- Shelters fill up; carry a tent or hammock too.
- Use a bear canister or hang your food where required, and follow local rules on food storage.
- Lyme disease is common along much of the trail: check for ticks every day.
