If you make the trip to Parque Nacional Torres del Paine in Chile, there is one thing you MUST do while there whether you’re hiking the circuit, the W, or staying just one night. I personally demand that you visit the Mirador Torres del Paine at sunrise.
The Mirador Torres del Paine is a lookout point that gives a breathtaking, up-close view of the park’s namesake massive granite towers. Of course, you can visit this gem of a spot any time of day, but the best views are at sunrise when the towers turn a shockingly bright orange. (Photos don't do it justice, so you'll have to check it our for yourself.)
The best way to access the Mirador at sunrise is by camping the night before at Campamento Torres del Paine, which is situated at the foot of the mountain. If you don’t have camping gear of your own, you’ll have to stay at Lodge El Chileno (the nearest refugio) or rent camping gear. If you stay at the refugio, plan to wake up around 3:30 or 4am to start your trek to the Mirador, depending on the time of year and when the sun will be rising. The trip should take you two and a half to three hours.
Good luck, and don't forget your camera. This is certainly a frame-worthy sight.
