In 1994, he returned again to Karakoram, accompanied by Andrew Lock and the Swedish climbers Mats Holmgren and Nicolas Gafgo. Their object was Broad Peak, and their goal was a first ascent of the hitherto unclimbed south-southwest ridge, on which several reputable climbers had failed. They also failed and had to turn back to below 7000 metres. Afterwards, they focused on the regular route to the summit, where, on the first attempt Lock, Holmgren, and Kropp reached the foresummit. Kropp made another attempt at the main summit and succeeded after a fast, non-stop solo climb.
