Taupo, New Zealand
Wake up at 530 (yes am!!) to do the mammoth 17km / 7hr hike that is the Tongariro hike. Scenery on way to national park is awesome - drive by lake Taupo for ages and then go past Mt Doom and other Lord of the Rings scenery.
Hike itself is amazing - 1st half is 'challenging' as the brochure puts it - massively up hill - rocky, molten lava, mud terrain!
Have lunch by the Emerald lakes - and then continue hike through countryside, rainforest, hills and mountains...
