Passing point of one of the variants of the trans-Pyrenean path (GR-11.2) that connects the Chistau and Benasque valleys. Its name, Grist, comes from the sub-valley into which it flows on its eastern slope, although it is also known as Collado de la Forqueta because of the peak that presides over it, which is also called that.

The second highest peak in the Pyrenees, whose ascent is increasingly popular due to the overcrowding of Aneto and being a little more affordable for those who run up it.

Beautiful lake at 2676 m altitude that serves as a common place to spend the night in summer (with the same being allowed, above two thousand meters, between dusk and dawn). All Aragonese lakes are protected as they are included in the Inventory of Singular Wetlands, so any activity that could modify the quality of their waters is prohibited. While bathing is not specifically mentioned, it is understood that bathing with chemicals on the skin such as sunscreen, deodorants, perfumes or creams is negatively affecting the quality of the water, so it cannot be done. You can read the protection decree and the list of wetlands included here: aragon.es/-/humedales-de-aragon
