The alerce tree (Fitzroya cupressoides) at the centre of Los Alerces National Park in Chubut Province is 2,600 years old — it was a 200-year-old tree when Rome was founded, and the forest surrounding it has never been logged, never been cleared, and has had no significant human disturbance since Patagonia was first settled. Reaching it requires a boat journey across the turquoise Lago Verde and then a walk through old-growth forest where every tree is between 500 and 1,500 years old. The alerce trunk is 2.2 metres in diameter.

Los Alerces National Park was established in 1937 and inscribed as a UNESCO World Heritage Site in 2017 to protect one of the last significant stands of Fitzroya cupressoides — the Patagonian alerce, the second-longest-lived tree species on Earth after the bristlecone pine. The park covers 263,000 hectares of Patagonian Andean forests, lakes, rivers, and glaciers, with the 2,600-year-old specimen (known as Abuelo) located on a small peninsula in the Lago Menéndez sector accessible only by boat and foot trail. The park's river system — the Futaleufú, Amutui Quimei, and Yelcho — supports one of the most significant wild trout populations remaining in South America. The Arrayán and alerce forests in the park's eastern sections contain trees of confirmed ages between 500 and 1,200 years, none of which are individual specimens in the tourist sense but a functioning ecosystem in which the oldest trees are the least exceptional feature.

Solo

Walking the path to the 2,600-year-old alerce alone, through forest that has not changed in any meaningful way in four centuries, produces a temporal recalibration available nowhere else in Argentina. The boat crossing before the trail adds a physical transition that prepares the scale.

Couple

The full Los Alerces day — boat across Lago Verde, walk to the ancient alerce, return through riverside forest — is complete in itself. The park's infrastructure is sufficient for the experience without being sufficient to make it convenient, which is precisely right.

Family

The ancient alerce is the kind of object that makes scale concrete for children — a tree that was already old when medieval Europe was being built, explained at the base of the trunk itself. The boat journey and the forest walk make getting there an experience rather than a transit.

Friends

Los Alerces for a group means multi-day camping in national park forests, fly-fishing the Futaleufú, and kayaking between lakes connected by short portages — the infrastructure supports independent exploration at a depth that day-trip visitors cannot access.

Why This Place
  • Alerce trees here were saplings before the Roman Empire — among the longest-lived organisms on the planet.
  • Boat trips across Lago Futalaufquen deliver hikers to the Alerzal trail, where the oldest trees require hours to reach.
  • The park has no mobile signal and no wifi — the forest silence is the attraction, rangers reinforce the off-grid nature of visits.
  • Campsites fill months in advance for January and February — arriving without a booking in peak season means turning back.
What to Eat
