Mera Peak can be climbed in as less as 14 days, but unless you are a highly experienced mountaineer with deep knowledge about the altitudes and climbing in the Himalayas or other high-altitude peaks, we recommend at least 18 or 19 days. The greater number of acclimatization days, the higher the possibilities to avoid altitude sickness and a successful climb. Different operators offer different routes and trip duration for Mera Peak climbing. The shortest route to Mera Peak is the most difficult route that heads straight to Zatr La Pass after landing in Lukla. Himalayan Glacier uses the widely preferred route through the remote and beautiful villages exploring the picturesque Hinku Valley, after landing in Lukla. This route gives you plenty of time to acclimatize to the high altitude. The third route is along the regular Everest Base Camp trek up to Namche Bazaar and then heading towards the Mera Peak base camp, high camp and finally the summit.
