Marinelli Glacier is the most beautiful and longest of all. It is the largest of those that spill down from the backbone of Darwin Mountain Range.

After crossing the Magellan Strait, the flight goes into Whiteside Channel, between Dawson Island and Tierra del Fuego, at the southeast entrance of the channel. Here, we can admire a body of water called Bahía Inútil, which leads to Almirantazgo Sound, along the Darwin Mountains and we arrive at Ainsworth Bay, a coastal inlet where Marinelli Glacier is located. The enormous ice walls of the Marinelli Glacier are almost 40 meters high.
