Preparing your backpack...
Luggage and bags: Take a good, comfortable backpack, and avoid any 'hanging' item (bags, bottles, etc), in order to keep your hands free.
Clothing/Shoes/Weather Gear: Trekking boots, sandals, windbreak jacket, Polartec jacket, short pants, hat. In winter, add to the list: helmet, Polartec pants and balaclava, plastic mountaineering boots, rackets, randonee skis (optional).
Toiletries and Medical Supplies: Band aids, aspirin,high factor sunscreen, if you're going to the glacier: acetazolamide to prevent AMS (Acute Mountain Sickness).
Photo Equipment: A good manual camera is ideal in winter (low temperatures freeze automatic one's batteries). Wide angle lens, a medium telephoto or zoom lens, polarizing and skylight filters. Cable release for long-time exposures at night. 50 or 100 ISO film is perfect.
Camping/Beach/Outdoor Gear: This is absolutely a camping place, so bring: tent (3-season for summer; 4-season, expedition-class in winter), camping stove, , In winter, besides the eventual mountaineering technical gear, add to the list: ice axe, crampons (both needed to climb the glacier in any season)
Miscellaneous: Headlamp, extra fuel (no liquid water around in winter), GPS, VHF transceiver tuned at 150.625 MHz (Mountain Rescue). No cell phone works in there (just VHF radio and Satcoms)
- Hiking and Walking
Luggage and bags: During the winter, the weather can get very cold. When I went up the canyon, there were 7ºC at noon. So bring up warm clothes, a nice scarf, and something to cover your head. It can get cold, as shown in the picture. Frozen water and snow can be seen everywhere.
