Adwick Washland

The newest of the RSPB's Dearne Valley satellites, a block of farmed fields between Bolton upon Dearne and Harlington reflooded into wet grassland and marsh on the north bank of the River Dearne. A bridleway runs through the site and about 2.5km of permissive paths take you round the perimeter and back along the river, with a short spur to a central viewing point. The RSPB's stated rule here is "Under control dogs welcome", which makes it one of the very few Dearne Valley reserves where a dog is not restricted to a lead. There are no toilets and no cafe, and the paths are grass and stone rather than surfaced, so it is heavier going than the trail at Old Moor.
