Chukkung Ri (5520m) is another classic trekking peak in the Khumbu. Located just behind the town of Chukkung, the trail beings at the obvious trailhead on the north side of town, passes through a small rocky plateau (often full of grazing yaks), and then begins a steep and somewhat sandy climb up. It's pretty much straight up, with a small flatter shoulder about halfway up, and then the steep trail continues to a ridge around 5350m.

Nangkartshang Peak is one of the classic "trekking peaks" in the Khumbu. It is accessible from either Pheriche or Dingboche, though I will suggest the standard route from Dingboche (as is reflected in the GPX file), as this seems like the more obvious, aesthetic choice.

The route can either be completely snowed over or completely dry, depending on the weather and time of year. Your author has climbed it in both conditions (snow in March and clean in late October).

Scenic Marathon route along the Alpstein mountains. Starting in Wasserauen, go on to Schaefler, Säntis, Lysengrat, pass the Altmann ridge and then along Saxer Lücke to Hoher Kasten.
