One of my favourite places to go dog walking near Bodmin is Respryn. It has a pay and display National Trust car park which lets you follow the river up or down. If you follow it up stream your dogs will get to explore winding paths with multiple places for them to swim and play.

My favourite direction to walk is down river, from the car park you cross the bridge on the road and take a right along the river side trail. There are plenty of bathing spots for dogs and lots of different trails to be explored. As a dog walker it is great coming here so the dogs can socialise with others and enjoy a good swim.
