in Exmoor · South West
Constant gradient flume-type run: great fun but challenging at the grade (nothing hard, just continuous).
There are 3 gauges alongside and below a small weir just upstream West Luccombe: the 3rd gauge should read 1 at a minimum.
Takeout just upstream of West Luccombe. Keep heading up the steepest lanes until reaching the putin at the highest road access.
