Saint Paul karst

The St Paul Mountain Range consists of limestone, and is a typical tropic karst area with sharp ridges, and rounded peaks called towers. It shows pinnacles, shafts, dolines and limestone cliffs. The principal feature of the park is an underground river, more than 8km long and known as the Subterranean River or St Paul Cave. The river flows underground for almost its entire length. Its spring is at an altitude of 100m asl, 2km southwest of Mount St. Paul. Soon it is swallowed by the cave and reappears at St. Paul's Bay, where it flows directly into the sea.

In doubts of making a decent photograph of it's main feature from the inside without special permit to go beyond the typical tourist path, I set out to search for a vista where I can capture the grandest of this range. With wild colors flashing behind me, I settled for this scene where I always dream of exploring it's still unknown cavities.
