Contact us directly to book your group tour. Depending on the size of your group, you’ll board one or more boats.
When a reservation is confirmed, places are reserved for the group at the scheduled time. In the event of a delay, the driver must inform the “underground lake” by telephone at least 45 minutes before the scheduled arrival time.
If the “Underground Lake” is not notified of the delay, places will be put back on sale and the group will have to wait for the next availability in the same way as individual visitors.
Around 30 minutes on the boat plus 10 to 15 minutes for our new visitor center. For a stop-over with a group, 60 to 90 minutes are needed from the time the clients get out of the bus until they are back at the parking lot.
4 boats are available for a total capacity of 120 people.
1 boat with 16 seats, 2 boats with 32 seats, 1 boat with 40 seats.
