Editorial Methodology
This page exists so you can judge the comparisons on this site rather than trust them. We compare tour listings, official visitor information and recent traveller feedback. We do not operate or personally conduct these tours, and nothing here is written as if we did. The Marble Caves tours comparison sits on the homepage.
What this site is
An independent comparison of the boat and kayak trips that visit the Capillas de Mármol from Puerto Río Tranquilo and Coyhaique, plus the practical information a visitor needs before booking one. We are not a tour operator, a travel agency or a seller of travel. We hold no bookings, take no payments and have no staff in Chile.
Every booking happens on the operator's own platform under their terms. If something goes wrong with a trip, the operator and the platform are who you deal with, not us.
Where the tour data comes from
Prices, durations, ratings, review counts, inclusions, age limits and cancellation terms are read directly off each operator's own listing and reproduced with the date they were read. Every tour page carries the same fields in the same order so the six trips can be compared line by line, and each one states its own "price last checked" date.
We do not copy operator marketing descriptions. Where an itinerary time or an inclusion is quoted, it comes from the listing's own itinerary block, which is also where the time-on-the-water figures on this site come from.
Where the destination information comes from
Sanctuary status, access rules and transport routes are checked against official Chilean tourism information and recent first-hand visitor reports, then dated on the page. Walk-up prices at the Puerto Río Tranquilo pier come from a published traveller price check of November 2025: about 20,000 CLP for the standard boat circuit, 30,000 CLP for the extended route and 50,000 CLP for kayaks. Currency conversions state their rate and date.
Where sources disagree, we say so and pick the better-evidenced number. The age of the caves on this site is 10,000 to 15,000 years, from a published interview with geologist Francisco Hervé Allamand, not the 6,000 that circulates in travel blogs. Climate figures are long-term averages from published climate records for the Aysén region, not a forecast.
How traveller feedback is used
Traveller feedback reviewed: more than 125 verified reviews across the tours compared, plus the platform's own category sub-scores where published.
We quote reviews with the reviewer's first name, country and the month they travelled, exactly as published, and we do not edit them into something more flattering. Where a review states a limitation, such as extra paddling against the wind on the long kayak route, we quote that too. We never write testimonials. Two of the six listings are new and carry no reviews yet; we say so on their pages rather than borrowing praise from elsewhere.
What we cannot verify
We do not ride along on the tours, meet the guides or audit safety records. We cannot tell you whether the lake will be calm on the morning you visit, whether a particular captain is careful, or whether a listed inclusion appeared on the day.
We also cannot see live availability or the price you will be quoted for your date. The figures here are starting prices at the time of the check; the number that matters is the one on the checkout page.
How affiliate links affect this
Links to tours are affiliate links. If you book through one, the platform pays a commission and you pay the same price you would pay going directly. The full arrangement is set out in the affiliate disclosure.
Commission does not decide which tours appear, the order they sit in, or what is said about them. The cheapest trip on the site earns the least and leads the comparison table, and the site's plainest warning, seven hours in a van for ninety minutes on the water, sits on one of the more expensive ones.
Corrections
Prices move, operators change hands and rules get rewritten. If a number here is out of date, tell us what you found and when you were there. Corrections get made and the check date on the page is updated with them.
