The first few kms act as a warm up to Ibbeth Peril Falls - a 3m slide into a large plunge pool. To the right of the fall is an undercut cliff containing Ibbeth Peril Cave - a pothole which you won't want to be anywhere near! Below this are three more hard falls, all of which have now been paddled, but a portage of the middle one may be advisable. The river then eases off to grade 3, before becoming flat for the last few kms down to Dent.
Rainchasers is best experienced as an app.
