The Guyot Campsite is located in the center of the Pemi, just outside the Pemigewasset Wilderness Area, near the top of Guyot Mountain. There is a 12-person log shelter and 6 4-person tent platforms at the site. The spring does not always run in cold, dry weather. Use is first come first serve and there is a fee collected by an on-site caretaker in the summer season. This is a very popular destination on summer weekends, leave early to help ensure a spot.
The name Guyot is pronounced Gee-Oh, with a hard 'G'. It was named after Arnold Henri Guyot, a professor of Geography at Princeton who did extensive exploring and mapping in the White Mountains in the mid-1800's.
This campsite is a long way from any trailhead. The easiest route is to come in via the Zealand Trail to Zealand Falls Hut and then climb the Twinway before turning south on the Bondcliff Trail. You can also come in from Lincoln Woods via the Wilderness Trail before climbing the Bondcliff trail over Bondcliff and Mt Bond. One other choice is to take the North Twin trail from the Haystack Road, to North Twin, the North Twin Spur trail to South Twin, to the Twinway and Bondcliff trail.
