Even though the Pisco circuit does not require technical mountaineering knowledge, it requires climbers to be in great physical condition. In addition to the high altitude, the last 800m of the climb are glacial and the weather conditions are constantly changing; therefore, you will require a guide to ensure your safety. Do not attempt the climb on your own if you do not have significant experience with glacier travel, and don’t forget to get official permission from park officials if you are climbing solo.
