The activity lasts about 8 to 10 hours, depending on group size and lighting conditions. Starting times vary, so check availability when booking. Be sure to arrive 15 minutes early for check-in and safety briefing.

What to Wear and Bring

You might want to bring a camera (preferably waterproof or in a protective case), a water bottle, and perhaps some snacks for after the descent.

Weather and Visibility

The Heavens Light is a weather-dependent phenomenon. Clear skies and the right season increase your chances of witnessing this spectacle, but it cannot be guaranteed. The descent and exploration are impressive, even without the light beam.

Age and Health Requirements

Participants must be at least 12 years old and in good health. The activity involves vertical climbing and physical exertion, so it’s not suitable for those with serious heart, back, or altitude issues. Pregnant women are advised not to participate.

However, a few caution that weather influences visibility of the light, so patience and realistic expectations are important. The overall consensus is that even without seeing the light, the adventure of descending into the cave and exploring its vast interior is well worth the effort.
