Caves

Postojna and Skocjan caves – Slovenia's wonderful underground

In Slovenia's karst landscape, there are two of the world's most delicious caves - Postojna Cave and Skocjan Cave. So close to each other, yet so different. I have visited both.

Yanchep National Park - among caves and black cockatoos - Australia

45 minutes north of Perth in Western Australia is Yanchep National Park, an important wetland area for the area's birds and with several limestone caves with unique wildlife. We have visited the Crystal Cave and hiked around Loch McNess.

Carlsbad Caverns National Park - Otherworldly views underground - New Mexico - USA

Some of the world's largest limestone caves can be found in the New Mexico desert. Wander down into a fairytale landscape of stalagmites and stalactites - and a few hundred thousand bats.

Undara - Queensland outback adventure - Australia

The dark red termite mounds along our path get bigger and bigger the further from the coast we go. Just when I think we've reached the end of the world, we suddenly pass a house. Someone lives out here. Far from everything. We are heading towards the lava tunnels of Undara National Park, in the northern Queensland outback.
