Follow the waymarked GR9 from the Col du Coq past the Trou du Glaz onto the plateau above. At the signposted junction follow the path up towards the summit. After about 350 metres there is an obvious spoil heap 40 metres on the left,which is Gouffre de la Pulpite Irréversible. Continue up the track for a further 50 metres and follow a line under the trees on the right. Gouffre du Coeur is about 100 metres from the path. Note: the author has yet to see this entrance!
