Yanchep National Park - Cave Tour

We were lucky enough to arrive early and experience a "private" tour of the crystal caves. Formed from limestone, the caves derive their name from the wealth and range of stalagmites that can found inside and can be seen below. I strongly recommend a visit if you're in the area.

The Labyrinth of Buda Castle

Located on a side street on Buda's Castle Hill is probably one of the most unusual tourist attractions I've ever visited. Open 24 hours a day, The Labyrinth runs through the tunnel ways and caves that are part of the natural formation of the hill.
The first half comprises of a look of sorts at labyrinths through history - Prehistoric cave painting are barely illuminated in the dim light are followed by strange statues as you walk along the Path of the Magic Deer and The Labyrinth of Love. It’s also around here that you find a fountain of wine, though it is recommended that you don’t take a sip.

It's during the second half of the labyrinth that things get really strange. The Labyrinth of the End of History features an imaginary excavation of modern day fossils, complete with straight-faced “explanations” of their discovery and history. Next to this is the European Pantheon, with an assortment of found items from across Europe displayed in Perspex and given titles such as Apollo of Kalamata and Jupiter of Kiev. It reminded of the second half of the Tunnel Tour under the Kiek in de Kok - the displaying of everyday modern items as of another time.

I recommend a visit if you're visiting Budapest, though it does feel more like the work of practical jokers than an actually tourist site - that would explain this display as you are on head out of the final section:

Kiek in de Kok - Tunnel Tour

Beneath the streets of Tallinn, Estonia lies a number of passages that ran under the city's original defensive bastions built in 1630's. It's possible to visit these passages as part of tour organised at the Kiek in de Kok  (translation: Peep into the Kitchen) tower.

Following an audio-visual presentation on the history of Tallinn and its defences, you're taken down into the tunnels themselves. The tour is split into 2 parts with the first detailing the tunnels usage through the ages, heading into the past with depictions of them as a haven for tramps and punks, shelters during the soviet era and bomb shelters during World War 2 before detailing the tunnels original construction.

The second part of the tour looks to the future, specifically to the year 2219. As you travel on a sideways train a presentation plays out detailing the challenges facing the planet over the next few years. The journey ends in a small exhibition with everyday items of today display as museum pieces.
