Highlights of Paine
Hikers list different highlights. But everyone includes these (assuming the weather cooperates):
The bleak, lifeless Towers of Paine just might be the highest stone towers in the world. Try not to miss seeing the top of the highest, De Agostini tower (2850m). Wait an extra day, if needed, for the the clouds to clear, even briefly.
There is a free campsite (Campamento Torres) less than an hour away from the lookout. When you get to that campsite, set up your tent then head up to the lookout if the weather is clear.
If it is overcast, set the alarm for early morning then scramble to the lookout for dawn, the best time to take photos. This gives you two chances to see the peak tops.
The very adventurous can sidetrip past the towers to visit Campamento Japones (Japanese camp), an old climbers base. And the appropriately named Valley of Silence. (8km return)
Note that many of the postcard photos of Paine are taken some distance from the Circuit. You should allow extra days to get out there if you wish to see those views yourself.
Expect the Unexpected
Patagonian weather is bizarre. Expect wind, snow, rain and sunburn every day.
Trail & weather conditions warp quickly. Use common sense. Theres every chance youll change your route based on weather.
Open-ended Itinerary is Best
Take as many days as you can, deciding day-by-day where to lunch and where to set up your tent. If the sun appears stop & take a rest day.
Hikers with a tent need make no reservation to camp. No commitments.
And you can buy (expensive!) food en route if you start to run low on anything.
