A short, steep mountain-surfing stunt if you've done everything else in upper Wharfedale and it's still raining. Point downstream and hold on - that's about it. Be sure to find the eddy below the long slide and take out.... there's a fence just below.
From Buckden village, carry up the beck a couple of hundred yards to below the waterfall, putting on at the (too shallow) plungepool.
Rainchasers is best experienced as an app.
