Watchet is lucky enough to be nestled between the Quantock Hills Area of Outstanding Natural Beauty and Exmoor National Park. Both excellent places for mountain biking due to the rich variety of habitats and landscapes, from coast to woodland to hilltop heathland, this area is nationally renowned for the quality of its mountain bike trails.
In order to plan your route you will need an Ordnance Survey Explorer 130 map for the Quantocks and for Exmoor an Ordnance Survey Explorer OL9.
Please ensure that you always stick to bridleway paths and be aware of walkers and wildlife in your path.
