Lost World 7 hour Epic

One of the best things you can do in this country - Lonely Planet travellers guide. Abseil 100m into this amazing cavern as per the 4 hr option, but this time wearing a wetsuit - you're heading off to explore the Mangapu river passage.

The 100m freehanging abseil will astound you, but on this option that’s only the beginning. Spend the rest of the day walking, wading and swimming through the cavernous passages of this famous underground system. Yes you need to be moderately fit (e.g. go bush walking for a day), but the trip is intended for complete novices - all you need is a swimsuit & a smile! See Fossil giant oysters and whalebones; giant flowstone (looks like icing sugar running down the walls). Lots of fun & optional challenges - water jumps; climbs and spiders. Includes an absolutely fantastic glowworm display.

Includes lunch & a BBQ dinner as well as all equipment (helmets; lights; wetsuits; ropes; harnesses; boots etc). If you’re looking for top adventure, this is the one thing you must do - it's the Ultimate!
