Trekking in Nepal is best if done during spring or fall seasons although it can be done throughout the year. However, to undertake any of the expeditions in the country, it is not possible to do it during any other time besides the particular season. Normally, the Camp 2 expedition starts from mid-April. So, all climbers must arrive in Kathmandu by the second week of April if you wish to do this expedition. This is the best time as the weather is clear with sufficient sunlight during the day and it is less cold than in winters. There isn’t heavy snowfall to disrupt your climbing route.
