Leaving the calm surroundings of Puerto Natales and our bike-friendly Hostal Don Guillermo, four of us including Andrew we’d met in Ushuaia and his buddy Hilton set off in high spirits for some serious trekking among the last glacier strongholds in the world. A 10 day self-sufficient trip around the complete circuit of Torres del Paine National Park, a UNESCO Biosphere Reserve boasting 227,000 hectares in the Andes. On arrival after three hours on the bus, we learnt that the full circuit was closed for the season; we’d have to be content with conquering the ‘W’ trail. Better to be over-prepared than under I thought, even if were carrying twice as much food as required in shoddy rucksacks – although it didn’t weigh our enthusiasm down. We’d just have to feast at every meal.
