NAC is primarily an outdoor sports club for adults, although members under 18 (but above 16) are welcomed as long as they are accompanied by a responsible adult. NAC members are expected to take responsibility for themselves in the first instance and formal supervision of members unable to take responsibility for themselves is not offered by the club. Members participate in club activities at their own risk. The main purpose of NAC is for like-minded people to get together and participate in various outdoor sports, whilst having some fun along the way. The club accommodates people of varying abilities and of varying levels of commitment, with a hardcore of regular members that have been active for many years.
NAC is based is the quiet dale of Nidderdale, home to the river NIDD. Nidderdale is bordered by the Yorkshire Dales National Park and falls within an area of outstanding national beauty (AONB) that covers 233 square miles. Nidderdale incorporates both a traditional upper Dales valley of steep valleys, exposed heather moorland, picturesque villages and numerous sheep farms with flatter more pastoral landscape as the river Nidd winds its way down the Dale towards Ripley. Within Nidderdale is the magnificent natural phenomenon of Brimham Rocks, the spectacular How Stean Gorge (nicknamed Little Switzerland)and the show caves of Stump Cross Caverns. Whilst the small town of Pateley Bridge serves as a major tourist attraction and is home to the Nidderdale Agricultural Show, the largest town nearby is the pretty spa town of Harrogate 12 miles away, which although not strictly in Nidderdale is still a major tourist attraction for those coming to Nidderdale.
Needless to say Nidderdale is a perfect venue for outdoor sports of all types and for all levels of fitness and ability. NAC is based in Nidderdale and therefore many of its activities are in Nidderdale but the neighbouring Dales of Wharfedale, Wensleydale, Malhamdale are also frequently visited, as well as venturing further afield to Scotland, The Lakes, Wales and Northumbria for weekends and longer trips.
