Ah I remember on a trip I went to Nepal around 2008; we arrived in Kathmandu and stayed their for a few days. This was a planned climbed with adventure peaks (we climbed Broad Peak), nonetheless it was a great experience even though we didn't do much other than acclimatization for a week or two and finally summit (a lot of us didn't though). A little side note what would've been a great idea would be going on the Everest Base Camp Trek, I hear the views are amazing of the Himalayas
