NH Tracing, Redlining, and White Mountain Trails all refer to the same collection of trails described in the guidebook. No matter which name you use, you’re working towards the same goal of experiencing these paths.
This site is not intended for planning or navigation. Trail data may contain minor errors or inaccuracies, and this collection is not the official list (though it includes most of the known trails). Please refer to official sources and use good judgement in the backcountry.
Use the green circles to mark a trail as completed. After marking a trail, tap the calendar icon to add a date of completion — the date will replace the icon once selected and can be edited by tapping again.
