We set off and walked through the castle, heading down around the side of the castle, towards the allotments, and followed the route along the river. We completed a there and back route, but there are plenty of options for circular routes.
The route we were going to take was blocked by a lot of cows, hence turning round and coming back the same way 😂
If starting at the castle the nearest postcode is: CA22 2JW. There is free parking on the street outside and for those without a car there is a bus every half hour to Whitehaven.
