Discover an unusual lava tunnel
There's a mixture of shapes and colours in this tunnel formed by an old lava flow from Piton des Neiges.
This route immerses you in the history of Reunion Island's first volcano and reveals unusual calcite and magnesite formations.
A trip that subtly blends local underground exploration with a more extreme "caving" side and a fun zipline.
Meet at: 9.00am
After getting your equipment (helmet, headlamp and harness), a five minute walk takes you to the edge of Bassin Bleu in the Saint Gilles ravine.
A "via cordata" secured by your instructor enables you to access the entry point for the tunnel, 6 metres above you.
Once in the lava tunnel you will walk for 100 metres until you reach the "low ceiling" section of the network. Fifteen metres on all fours and you get your reward!
The next part takes place in big caves where you can admire stalactites and lava benches and more surprisingly immaculate white calcite stalactites and magnesite formations. This tunnel ends with a lava plug and after a quick well deserved break you return to the starting point.
The piece de resistance - a 30 metre zipline deposits you on the banks of the Bassin Bleu!
Ends at: around 12.30pm.
