The natural entrance

The entrance we started at was artificial and the point we exited was the natural entrance. This photo gives a slight glimpse of what we saw. To the right is the walkway pinned to the cave wall, which we followed for two kilometers, together with bridges, and on the left is the exit. We had bought tickets for a second extended tour so we followed the trail outside for more great views of the gorge, this time on daylight an photography was allowed.
