This place is ideal for acclimatisation on the way to Gokyo.
One should spend a minimum of one night may be two for better acclimatisation.
The place is absolutely beautiful and there are several glacier walks which will help acclimatisation.
Get here early, climb one of the ridgelines, visit the medical centre or just relax in the sunshine amongst the yaks in Macchermo! The best pace on the Gokyo trail to spend the day before the final ascent! Staying here should leave you feeling strong for the ascent of Gokyo Ri/Renjo La in the coming days.
Spent two days in Macchhermo acclimatizing on our way to Gyoko. It is a lovely little village with a medical center. The two doctors that where there on my visit where lovely and very helpful and we where able to check on oxygen levels which was very interesting.
