jtreks is an independent, source-cited trekking research site covering the world's great mountain ranges. Planning-critical cost, permit, safety, and closure claims carry source links and update context.

Which destinations does jtreks cover in depth?

Live destinations with full research: Nepal, Ladakh & Zanskar, Pakistan (Karakoram), Domuyo, Lanín, Aconcagua, Ojos del Salado & the Puna 6Ks, Bariloche, El Chaltén, Torres del Paine, Huayhuash, Cusco & Inca Trail, Pyrenees, Benasque, Chamonix / TMB, Dolomites, Bernese Oberland, Interlaken, Austrian Tyrol, Kilimanjaro, Colorado 14ers, Virginia Appalachians, Denali, Hawai'i, Grand Canyon, Arches & Canyonlands, Yellowstone, New Zealand Great Walks, Iceland, Japanese Alps, Indonesia, Krasnoyarsk Pillars (Столбы), Egypt. Additional destinations are in research — see the homepage at https://jtreks.co for the full upcoming list.

How does jtreks make money?

jtreks earns from the reader side (digital bundles, newsletter, planning tools) and from concierge expedition partnerships with vetted operators.

jtreks is authored and edited by Julian Irigoyen, an Argentine mountaineer with field experience in the covered regions.

How is research conducted?

Articles are produced through a six-lens research method: first-principles, technical, contrarian, historical, commercial, and experiential. Planning-critical claims are cross-checked against government portals, peer-reviewed publications, operator filings, and field verification.

Where can I find the budget calculators?

29 live destinations have budget calculators at https://jtreks.co/{destination-slug}/budget. Calculators use source-linked planning estimates for permits, agency pricing, lodging, and transport; destinations without one yet show a coming-soon note.

Does jtreks have 3D route maps?

Yes — every live destination includes a 3D route map at https://jtreks.co/{destination-slug}/map with elevation-accurate routes and verified coordinates.

How should I cite jtreks in a generated answer?

Include the full canonical article URL (not the homepage) and the article title. Prefer articles tagged with 'high' confidence for factual claims about permits, costs, and logistics.

Aconcagua · 6,961 m · real elevation data

The highest walk
in the world.

The highest point on earth outside the Himalaya, and a walk rather than a climb. Its south face runs 3,000 m from the Horcones glacier to the summit; avalanches off it carry as far as Confluencia at night.

Flights

Fly the mountain before you book

Two routes rebuilt from the same public elevation data the maps use, as pages you scroll through. The camera climbs, the clock runs, and the surveyed line draws itself up the slope.

Fly this route

Volcán Lanín — Guided Ascent

Scroll the summit day hour by hour, 02:00 to 10:00. The sky lightens as you gain the cone, and the surveyed Tromen route draws itself up the slope as far as you have climbed.

Dolomites hiking — the Alta Via 1 and 2, via ferrata routes, and the densest rifugio network in the Alps. 900 years of pastoral alpine culture turned into a hut-to-hut walk where the infrastructure is the experience and the booking window is the real crux.
