Unpromising start, but after 200m of ducking and diving through trees things improve. Golitha Falls are 2 successive fun gd4 drops, if you're not convinced at the putin walk down to have a look and see what you'd be missing.
Putin at the Goliath Falls carpark, getting on just below the bridge from the footpath. Takeout at Treverbyn Mill, the twin bridges just east of St Neot.
Rainchasers is best experienced as an app.
