In the highest camp in front of Larke La you should be prepared for simple conditions. If you come early, you have a better chance of getting a camp in one of the huts. If you arrive later, you don't have to spend the night on the meadow, but get very reasonable sleeping places in tents.
The atmosphere in the camp is super relaxed. In the meantime, most trekkers and groups have met, talked or even made friends several times. The next day is looked forward to with excitement and anticipation. Because then the highest point of the Manaslu Circuit is crossed at Larke La.
Tip: fill up your water reserves in the evening. Because in the morning the creek, in which you can fill up with water, could be frozen.
