This is a 3-part VF/KS with a long traverse between pts 2 & 3. The 1st part is relatively easy (& has an emergency exit at the end), but gets very busy at peak times so they built a new difficult variant (KS4.5 D/E). The second part is similar to the first (c.+150m) and cannot be bypassed so you just have to wait your turn. The traverse then leads to the Biwac where you can rest & from there you can climb all the way down again (KS3 C) OR attempt the final overhanging climb, which thankfully is not too long. However it is difficult in places (KS4.5 D/E) & should therefore NOT be attempted by beginners. From this final peak you can hike T4+ back down to Gumen. So overall a long route but with rest stops, a nice bridge and great views.
