The Association has six Branches that cover all of the county and offer a broad range of topics tailored to the diverse interests of their members.

Each Branch has its own committee which arranges a broad-based, annual programme of Devon-related talks, excursions and social gatherings. Indoor venues are largely used in winter and are selected on the basis of their suitability, comfort, and easy reach of public transport. Outdoor activities are largely run in summer months with an eye to ease of access and modest exertion.
