The signs at treeline warn that the area ahead has the worst weather in America, and that many have died there from exposure, even in summer. Pack as if the weather will turn, because up here it often does.
Start with New Hampshire’s hikeSafe list of ten, add the extras for above treeline, then the items for the season. Check items off as you pack. Your check marks are saved in this browser only, so you can clear them for your next trip.
The ten essentials
From hikeSafe, run by New Hampshire Fish and Game and the White Mountain National Forest. Bring these on every hike.
- A paper trail map. Phones die in the cold.
- And know how to use it with your map.
- They double as wind protection above treeline.
- With fresh or spare batteries.
- More than you think you need.
- Three blasts is the signal for help.
Above treeline, any season
Most Presidential hikes climb above treeline, where there’s no shelter from the wind.
- Even in July. The summit averages below freezing for much of the year.
- A puffy jacket or second fleece for stops and emergencies.
- There is no shade above treeline.
- For emergencies. Don’t rely on it to navigate.
- Decide before you start, and stick to it.
- Check it the morning of your hike. See our Weather page.
Summer
June to early September.
- Two to three liters for a long day.
- Black flies and mosquitoes can be fierce in late spring and early summer.
Spring and fall
Snow and ice linger on the summits into June and come back in September or October.
- Ice can coat the upper trails long before and after winter.
- For mud season and wet snow.
Winter
November to March, and later on the summits. Winter in the Presidentials is real mountaineering. Go with experience or with a guide.
- For deep snow below treeline.
- For blowing snow and wind above treeline.
- To protect against frostbite.
- Hoses and bladders freeze. Carry bottles upside down so ice forms at the bottom.
- Cold drains batteries fast.
- Only if you know how to use it.
- A beacon, shovel, and probe, and the skills to use them. Check the avalanche danger.
