Those passengers arriving on an international flight will be met at the airport by the tour leader or a local representative. Santiago is laid out in a broad valley below the snow-capped Andes, a cosmopolitan city of many museums, markets and parks. There will be time to relax before exploring the city on a walking tour. 

For a panoramic view over the city, we visit Cerro Santa Lucía, a central, rather romantic park. For even more panoramic vistas, a cable car leads to the summit of San Cristóbal, where you can join Chilean families wandering along the leafy paths. Other highlights include the Plaza de Armas, home to the capitals cathedral, the arty area of Lastarria and the famous fish market. Afterwards, have a beer at one of the pavement cafés in Bellavista. This is an Italian quarter of narrow streets peppered with bars and shops selling local lapis lazuli (only Chile and Afghanistan produce the stones in commercial quantities).

The museum and house of Chilean poet laureate Pablo Neruda is close by, and its unusual interior with an eclectic collection of paintings and bric-a-brac is well worth a visit.

There is also the option to climb to the icy peak of Villarrica volcano. This is a demanding trek which requires a good level of fitness. A local agency provides all the necessary equipment. The steep 1,400m ascent takes 5-6hrs through snow and icy conditions. Views down over the surrounding volcanoes, shimmering lakes and bright green deciduous forests are mind-expanding and at the top you are greeted by the sight of the deep, smoking crater.

Or you might explore the area on horseback. This is a 4hr optional trip into the Mapuche countryside originally settled by the Mapuche indians in the shadow of Villarrica and Lanín volcanoes and along the shores of the bright green Curilafquen Lagoon. You can even take a dip in the chilly waters if you dare!

Spend your days exploring the national park on foot. Follow a number of different walking trails winding alongside the glacial lakes and rivers with close-up views of tortured rock towers and needles rising 3,000m into a tempestuous sky. The difficulty and length of the available walks in the park vary hugely, and some may not be suitable for all passengers. The most famous hike is to the 'base of the towers', but this is also the most strenuous lasting at least 8hrs. There should however be something for everyone, so consult your tour leader about which hike would be best suited to you or for alternatives such as horse riding. Water and windproof clothing, as well as suitable footwear, are essential as weather can be very unpredictable.

The park authorities have been sensitive about keeping the site as natural as possible, and there are no shops or cafés within close proximity of the wooden viewing platforms, which are landscaped into the cliff. Just looking at the cliff-edge of the glacier, which towers 60m above the water surface and is an extraordinary 5km wide, is awe-inspiring in itself. But after a time you hear the unforgettable sound of the glacier calving a vast wedge of ice the size of a tower block and sending it smashing it down into the lake, where it divides and floats away as an iceberg.

There is an optional mini-trek on the glacier. Walking out on the ice is an extraordinary experience; atop this immense ice sheet you feel exposed to the elements, and you can explore the craggy, desolate landscape, peering into crevasses and deep water pools, squinting against the incredible blue of the ice. It is a 1-2hr walk on the ice led by a local guide, and crampons are provided.

Full-day excursion to the nearby Tierra del Fuego National Park, with its bright green deciduous beech forests cascading down to bright lakes and fjords populated by water birds and beavers. Walk along winding, narrow hillside paths to be met with views over the Beagle Channel, and learn about the flora and fauna of the area with your guides, who love the park and have devised their own nature trails. The 4-5hr walk is at a gentle pace, there are plenty of stops and a packed lunch is provided.

A guided tour of the city takes you to the most famous spots the city has to offer. Starting in the centre of the city, the historic heartland, where government buildings and churches mingle with chic shopping districts, which have a nostalgic, Parisian feel. The quintessential district La Boca with its cobbled streets and brightly painted houses is a must, as is the bohemian district of San Telmo, full of quaint old houses interspersed with antique shops, tango bars and expensive restaurants. Slightly further out of town is the Recoleta district, even more evocative of belle époque French and Italianate architecture. The area is home to the cemetery where Evita is laid to rest, and huge tombs line the alleys. During the winter months, wealthy female residents parade the streets in their fur coats and improbable, towering hairstyles, and take afternoon tea in the city's ornate cafés.

On your free day take a break from the city’s frenzy. Travel by motor catamaran across the River Plate border to Colonia in Uruguay (don't forget your passport) where you can wander cobbled streets and admire the squat colonial houses from the top of the lighthouse, and have a glass of wine or lunch in the yacht club.
