Route Grade Votings
A popular combination that avoids the wide crack on Spurven by a long loop out to the left. Included here so you have something to tick if you do it! Climb pitches 1 and 2 of Spurven then traverse 20m left along the ledge. Continue up the crux 3rd pitch of Colibrien, before traversing back right for the 4th and 5th pitches of either route.
I thought it was more sensible to climb the 1st and 2nd pitch of Spurven and the 3rd and 4th pitch (the superb crack) of Colibrien. A 60meter rope will run out if you try to combine the first two pitches of Spurven.
