For his 1996 ascent, Kropp left Stockholm on 16 October 1995, on a specially-designed bicycle with 108 kilograms (238 lb) of gear and food. He traveled 13,000 kilometres (8,000 mi) on the bicycle and arrived at Everest Base Camp in April 1996. Following a meeting of all of the Everest expeditions on the mountain at the time, it was agreed that Kropp would attempt to summit first. On 3 May, Kropp climbed through thigh-deep snow and reached Everest's South Summit, a point 100 metres (328 ft) from the summit.[5] However, he decided to turn around because it was too late in the day and if he continued, he would be descending in the dark. While Kropp recovered from the ordeal at base camp, the 1996 Everest Disaster unfolded. He helped bring medicine up the mountain. Three weeks later, on 23 May, he again tackled the mountain, this time successfully summitting without extra oxygen support.[6] He then cycled part of the way back home.[7]

He returned to Everest in 1999 with his girlfriend Renata Chlumska to undertake a cleanup, during which they removed 25 discarded canisters from the mountain. They also successfully summited together.
