A Typical Day During the Annapurna I Expedition
The Annapurna I climb is divided into three phases. Each phase has its unique significance that contributes to a successful expedition.
Preparation Phase (Days 1 to 5): The preparation phase involves thorough checking of your gear, equipment, and permits, attending expedition briefings, and meeting your team. From Kathmandu, you will travel to the scenic city of Pokhara before boarding the morning helicopter transfer to the Annapurna Base Camp (ABC). Upon reaching the ABC, you will participate in establishing your tents and detailed safety orientation, and prepare for the rotational climbs.
Training and Rotation Phase (Days 6 to 29): The training and rotation phase is conducted in a span of several weeks. During this phase, you will follow the crucial principle of “climb high, sleep low” to allow your body to acclimatize to the harsh high altitude conditions.
Your days typically begin with a climb from the Annapurna Base Camp to Camp I or Camp II. This is done to aid in acclimatization, making you familiar with the high altitude conditions, focusing on ropework and fixed-line practices before returning to the base camp. The routine lasts 6 to 10 hours.
Summit Push Phase (Days 30-37): The summit push is the most crucial and physically demanding phase of the expedition. You will navigate your way through Camp II, Camp III, and Camp IV, preparing for the final summit push, analyzing the most favorable weather window.
The summit day typically begins before dawn. You will give your best to conquer Annapurna I, followed by an immediate and careful descent back to Camp IV and gradually to lower camps. Upon reaching Base Camp, you will attend an immediate medical check, debriefing, and recovery.
