Chamlang is a spectacular peak situated in the remote Hongu Valley of Eastern Nepal. In the Sherpa Language Chamlang mean "big bird flapping wings" due to the shape of the mountain. The peak lies about 16km southwest of Makalu and has three majors summits: main (7319m), east (7235m) and central (7180m).

Chamlang is not a popular peak by any means. I found a few climbing reports (see "External Links") on the Internet but information is far and few in between.

Getting There

Virtually all climbers start the walk-in from Lukla. To get to Lukla, you can catch a mountain flight from Kathmandu. Flight cancellation is pretty common so it's wise to schedule some buffer days (both ways).
From Lukla to the Chamlang Base Camp, follow the route to Mera Peak up to the Mera La. There are two routes:
Lukla (2860m) - Puiya (2796m)  - Pangum (2846m) - Narjing Dingma (2700m) - Chalem Kharka (3440m) - Khola Kharka (4120m) - Kote (3500m) - Tangnag (4140m, 2 nights) - Khare (4940m, 2-3 nights) - Mera La - BC
Lukla - Chutanga (3400m, 2 nights) - Tuli Kharka (4400m) - Kote - Tangnag (2 nights) - Khare (2-3 nights) - Mera La - BC
The first option is longer but allows more gradual acclimisation while the second option involves a very steep ascent of the Zatra La (4600m) on the 3rd day.

Red Tape

You'll need a climbing permit for the peak and trekking permit for the walk-in.
Climbing royalty for foreigners: $500 for spring, $250 for fall and $125 for winter/summer.

When to Climb

Spring (March-May) or Fall (Sept-Nov)


There are many tea houses along the way from Lukla to Khare. However most big groups (mostly to Mera Peak) choose to sleep in tents and use facilities provided by the tea houses.
I also heard (from a lodge owner in Khare) there are now two simple lodges in the Hongu Valley but I can't verify that myself.

Re: Chamlang Peak Nepal 7319m (Main Summit)

Very sorry for the belated reply. Wasn't aware of your additions (never received a notification) . I updated the page with your info and added the 2021 climb up the N-Face. Thanks a lot!

Dutch women's expedition

I just read the book by Myra de Rooij about the 1988 Dutch women's expedition. I understand they got to the main summit. It's a great book and it is a pity it never got translated into English. Here are her photos from the climb:

Re: Dutch women's expedition

Thanks for the info, much appreciated! I updated the page with your new info. I clicked the link (,-droom-of-werkelijkheid), the english translation says they summited "the east summit"? "In the spring of 1988 Frederike Bloemers, Annet Boom, Gerda de Groene, Janka van Leeuwen, Marjolein Meere and Myra de Rooy successfully climbed the 7290 meter high east summit of the Chamlang in Nepal. ..."
