Devon welcomes visitors in all sorts of ways and one of them is to provide a lot of information and suggestions about how best to enjoy the towns as well as the open spaces. In Exeter there is a daily schedule of free guided walks: the “Red Coat Guided Tours”, these are highly recommended.
Most other towns have maps and town trails and many hours can be enjoyed strolling with a purpose to spot all the places of interest. Whilst learning more about the town there might be time to explore a market, participate in local festivals or simply partake in some local food & drink.
