From the post 0f July 2015. (The winch bridge just across from Bowlees was closed in 2018, so you had to follow the path parallel to Bowlees beck down to a bridge east of it, then back by the Tees. This opened again 2019) The next 2 miles are sublime for wildflowers, probably the most diverse in the country in July. We counted 85 separate types last year, less this due to the heat drying things up, we think: eg no alpine bistort. The extension from the car park upto Gibsons Cave is worth it, or rather the quarry floor on the way up, with twayblades and more orchids.
If you carry on past the High Force, to Bracken Rigg hill, then turn south and join the bridleway above the Dale for the return via Holwick Scar, then a path from Holwick to the bridge mentioned above, this makes a nine mile easy, lovely round.
