Take the short 1.5-hour loop if the Chapel, Cathedral and Caves are all you came for; take the 2.5-hour full route if you also want the quieter formations around Puerto Sánchez. A seat costs about the same either way, $42–75 per person, but the cheapest full route needs at least two people.

The full marble caves and chapel boat tour runs about 2.5 hours from Puerto Río Tranquilo. It follows the shore to Puerto Sánchez and the Panichini islands, then comes back past the Marble Tunnel, the Cathedral and the Chapel. Two tours sell it: the full boat route from $75 per person and the two-coves tour from $42 for two or more.
A former mining village; the listings mention stranded old boats and about 2 km of caves along this shore.
Small islands with their own marble caves, which the short loop does not reach.
A tunnel of pale marble near Puerto Río Tranquilo, on the way back to the main formations.
The tall arches of the Marble Cathedral and the Chapel islet; the boat passes beside them, not inside.

You board an open boat in Puerto Río Tranquilo, put on a life jacket and cross about 5.5 km of lake to the formations. There the boat slows beside each arch for photos while the guide explains how the marble formed. Guests mention plenty of time for photos and good explanations; on windy days the crossing back can be rough.
Departures are mostly in the morning: the classic trip leaves at 10:00, and the speedboat has slots from 07:00. Some listings say the boat noses into smaller caves along the way, but nobody goes inside the Chapel or Cathedral, whose interiors are protected. One guest had a 10:00 start moved to 11:00 the evening before, so leave some slack in your plans.
“Windy day made for a rough ride, particularly on the return trip. Spectacular views.”
A private boat costs $270 for a 1.5-hour loop or $500 for a 3-hour full route, and each takes up to 6 people, so for a family of five the short loop works out at $54 each. Private boats leave earlier than the shared trips, at 06:00, which also means calmer water on most days.
This is the live calendar for the classic boat trip, the most-reviewed Marble Caves boat tour: 1.5 hours from Puerto Río Tranquilo, leaving at 10:00. Pick a date to see real availability and the price for that day; for the full route or a private boat, use the Check dates buttons above.
Dress for wind and spray, not for the weather on the shore. Lake General Carrera is glacier-fed, the boats are open, and the crossing back is usually the coldest part of the trip. Bring cash as well: the village has no reliable cash machine, and some extras are paid locally.
The wind off the lake is cold even in summer; a fleece under a jacket is enough on most days.
Spray reaches the open boat. One short tour includes raincoats and waterproof trousers.
The light off the water and the white marble is strong.
No reliable ATM in Puerto Río Tranquilo; bring pesos for food and tips.
The classic boat trip holds 4.56 from 37 reviews, the only boat tour with a track record so far. Guests praise the explanations, the time left for photos and punctual, safety-minded crews; the complaints are about wind on the crossing back and, once, a start moved by an hour the night before.
