The tour begins with pick-up at hotels in Puerto Villamil to ascend to the upper part of Isabela, where a walk takes place among native vegetation and birds typical of the humid zone. After a short walk, the group arrives at the cave system known as Los Trillizos and begins a descent of approximately 150 metres to enter a 60-metre lava cave. With torches, visitors explore volcanic formations, narrow caverns and minerals such as quartz, enjoying an immersive geological experience before beginning the ascent and returning to the starting point.
