: Many hiking trails traverse the forests and public lands across North America. It has therefore become important for federal management to gain an understanding of total use on these trails. However, there has never been a formal attempt to estimate hiking on these long, backcountry trails. This paper presents an approach that utilizes two survey instruments (exit-site tallies and a trail-user questionnaire) and two primary estimation components (standard and augmented sites) to estimate hikers over a spatial and temporal span. For illustrative purposes, the methodology is applied to a 175 km segment of the Appalachian Trail from 1 June through 14 August 2007. Two alternative estimation methodologies are presented and compared. The model-based approach may be preferred to the design-based approach when sample size is small because it smoothes erratic strata estimates and yields smaller standard errors. However, the design-based approach relaxes an assumption and is more appropriate as sample size increases. In our survey of the Appalachian Trail, there was a 5.6% difference between the visitation estimates based on these two approaches, and such stability reinforces confidence in the methodology. Resume: Plusieurs sentiers de randonnee pedestre traversent les forets et les terres publiques partout en Amerique du Nord. Il est par consequent devenu important pour la gestion federale d'acquerir une comprehension de l'utilisation totale de ces sentiers. Cependant, il n'y a jamais eu de tentative formelle pour estimer la randonnee pedestre dans ces longs sentiers d'ar-riere-pays. Cet article presente une approche qui utilise deux instruments de sondage (des releves de sortie du site et un questionnaire destine aux utilisateurs des sentiers) pour estimer les randonneurs pedestres sur un horizon temporel et spatial. A titre d'exemple, la methodologie a ete appliquee a un segment de 175 km du sentier des Appalaches du 1 juin au 14 aout 2007. Deux methodes alternatives d'estimation sont presentees et comparees. L'approche basee sur un modele peut etre preferable a l'approche basee sur un plan lorsque la taille de l'echantillon est petite parce qu'elle adoucit les estimations des strates irregulieres et produit de plus petits ecarts types. Cependant, l'approche basee sur un plan assouplit une hypothese et est plus appropriee a mesure que la taille de l'echantillon augmente. Dans notre enquete sur le sentier des Appalaches, il y avait un ecart de 5,6 % entre les estimations de frequentation basees sur les deux approches et une telle stabilite renforce la confiance dans la methodologie.

Outdoor recreation is very important across the North American continent as [...]
