Perito Moreno is an iconic glacier offering an unforgettable glacial experience. It is one of the world's few advancing glaciers with a unique setup for all kinds of activities, making it our personal favorite in the world. The main observation deck is the best place to admire the sheer size of the glacier, with quite frequent opportunities to spot massive 200-feet-high ice walls cracking and dropping into the lake. TIP: Even if you book the incredible Big Ice Adventure or some other tour that includes a transfer from El Calafate, we recommend driving to the park on your own early in the morning and spending crowd-free time at the main observation deck. It is a totally different, intimate experience. TIP: When the time comes, you can join your group at the ferry station which is just 10 minutes drive from the observation deck. This flexibility makes it possible to visit the observation deck after the tour one more time and spend as much time as you want taking in incredible scale of this natural wonder.
