The trip to Chavonnesberg started late at 3:21pm from Thomas Hut, but being in the middle of summer (19 January 2013), there was plenty of sunlight left in the day. The way to Chavonnesberg follows the same initial route as if you are heading to Brandwagpiek (ie. through the narrow valley leading up to the peak but one you get to the saddle you proceed along the north edge of the ridge that connects Brandwagpiek to Chavonnesberg and “The W” range further to the West.
This ridge becomes very narrow and involves a bit of scrambling to get to the base of the Chavonnesberg (east) cliff face. Here, one could climb this face to the top with a rope, as it is probably a Grade 12 or so climb, but being on my own, opted to bypass the cliff by proceeding around it to the north following the rather sparse cairns.
You proceed in a westerly direction at the base of the north facing cliff until the cliff face becomes more negotiable, albeit rather steep terrain .Then it is a straight upwards clamber to the summit – the terrain here is steep (not climbing) and the going is exhausting but the summit is reached fairly quickly. 1 hour and 40 minutes later saw me at the summit of Chavonnesberg (1756m). The trip back to the hut was far less exhausting, taking an easy 1 hour and 35 minutes back to the hut by 7pm and summiting Brandwagpiek (1811m) en-route back.
