Hiking up to the base of the Towers is the most iconic part of the W-trek with the most iconic view in Torres del Paine. If you are doing it on your last day of W-trek (as we strongly recommend), you will start at Refugio Chileno and make your way up to the base (2-2.5h), and then all the way back down to Hotel Las Torres (another 4-5h) to the end of your epic W-trek adventure. The alternative way of doing it (and quite popular if you don't want to stay overnight) is an out-and-back hike from Hotel Las Torres. It is a much more strenuous hike with 3,418 ft of elevation gain, but still doable in about 7 hours. But we don't recommend this option for the reasons laid out below. TIP: One of the highlights of your entire trip to Patagonia is catching the sunrise touchinging the peaks of the towers — an absolutely magical moment. While we are usually on a comfy side of adventures, we made an exception by waking up in the middle of the night to start our hike. Even though it was rough at times (hiking in complete darkness without flashlight, knowing that pumas are wondering around), we never regretted our decision — sunrise over the Torres Del Paine instantly erased everything that led to that moment.
