Highlights of Gringo Trail

Amazon Rainforest (Bolivia)

The rainforest of the Amazon Basin extends over vast areas of the north-east of Bolivia. This is a region of enormous biodiversity of flora and fauna, with hundreds of species of birds and butterflies in addition to animals such as shy tapir, jaguar, howler monkey, deer and sloth. The region includes the protected areas of the Madidi National Park and the Noel Kempff Mercado National Park, the latter a UNESCO World Heritage Site. Staying in jungle lodges, you can explore the Amazon with walks through the rainforest and canoe rides along the rivers, spotting wildlife and learning about the importance and uses of the jungle plants.

Salar de Uyuni

The Salar de Uyuni, or Great Salt Desert, in south-western Bolivia is the world's largest and highest salt flats and one of Bolivia's most spectacular natural features. The salt lake covers some 12,000 km² at an altitude of 1,650 metres and the contrast between the bright blue skies and the blindingly white salt crust is spectacular. Three to four day tours of the region can be taken in 4x4s to explore the remarkable landscape and various sites of interest. In addition to taking the compulsory perspective defying photos, you can visit the village of Jirira at the foot of the Tunupa Volcano and explore the natural caves on the volcano, the volcanic Fish Island home to some enormous cacti and a salt works to learn of the extraction process. Other natural features of interest include Laguna Colorado, a bright red lake and Laguna Verde, a striking blue-green lake, which are coloured by algae and rich minerals and the geysers and thermal baths of Sol de Manana.

San Pedro de Atacama

The oasis town of San Pedro de Atacama is a base for exploring the dramatic natural features of the Atacama Desert in the north of Chile. San Pedro itself is a charming little town of white-washed buildings, dusty streets, some great restaurants and bars and countless travel companies offering tours of the surrounding region. The Valley of the Moon is a bizarre, lunar-like landscape with strange rock formations. Even amongst the crowds, watching the sunset here is a magical experience. Elsewhere the Salar de Atacama is the world's largest salt lake, its rich mineral deposits attracting many flamingos and other birds. The Geysers of El Tatio, located at 4,500 metres and surrounded by volcanoes, are best visited in the morning to see the water and steam hurling up from the geysers, thermal wells and fumaroles, with the morning light producing a magical effect. Other options in the area include scaling up and sand boarding down the sand dunes of Death Valley, visiting the Puritama hot springs and hiking some of the nearby volcanoes.

Quebrada de Humahuaca

The Quebrada de Humahuaca (Humahuaca Gorge) is located in northern Argentina along the valley of the Rio Grande from its source in the High Andes to its confluence with the Rio Leone 150km to the south. It has been a major cultural and trade route for thousands of years, known as the Camino Inca, and was used for 200 years to transport the silver mined at Potosi back to Spain. The valley features traces of several historical periods, from prehistoric hunter-gatherer communities, to the Inca Empire of the 15th and 16th centuries and the fight for independence in the 19th and 20th centuries. The scenery is this region is spectacular and the villages of Purmamarca, Humahuaca and Uquia are picturesque settlements in beautiful mountainous settings.

Iguazu Falls

Iguazu Falls can lay reasonable claim to being the most spectacular waterfalls in the world. Certainly, the sheer breadth of them, 275 distinct waterfalls across 2.5km, is without parallel while they are higher than Niagara Falls with heights of up to 80 metres. Located at the confluence of the Rio Iguazu and the Rio Alto Parana, the Falls can be viewed from both the Argentine and Brazilian side of the border - the Brazilian side gives great panoramic views, especially of the Devil's Throat area, with the Argentine side allowing you to get closer to the waters from above and below. The single most impressive waterfall is the Devil's Throat, reached on the Green Train or by a hike through the park. After walking across several bridges, you reach a platform right beside the spectacular and deafening cascade of water. Back towards the centre of the park, there are two circuits (Upper and Lower) that allow you to get very close to some of the other falls (Salto Bossetti is a particularly impressive and dampening experience) as well as giving some fantastic panoramic views. Depending on water levels, you can take a boat to Isla San Martin for a different perspective or a speedboat ride right up to the Falls themselves to get properly soaked. Iguazu is truly one of the must-see sights in the world and warrants extensive exploration of the National Park.

A short helicopter ride over the waterfalls offers a different and spectacular vista. Close to the national park is the Parque das Aves which contains many examples of Brazil's subtropical birds as well as mammals and reptiles. There is also the option to visit the Itaipu Dam, one of the engineering wonders of the world and second only in size to the Three Gorges Dam in China. With a dam 8km long and 65 storeys high and a reservoir that covers 1400 km², Itaipu supplies 80& of Paraguay's electricity and 25% of Brazil's.

UNESCO World Heritage Site: Iguaçu National Park

Rio de Janeiro is one of the most beautiful and vibrant cities in the world. Known as the Cidade Maravilhosa (Marvellous City), its setting is almost unparalleled - crammed between stunning white beaches and soaring mountains with the peaks of Sugarloaf Mountain and the Corcovado guarding its bay. The 1,300-metre long cable car ride to the top of Sugarloaf Mountain gives you spectacular views across the city and Guanabara Bay, which are matched by those on Corcovado on top of which lies the magnificent statue of Christ the Redeemer, one of the new Seven Wonders of the World. Back in the city, Rio's famous beaches (Ipanema, Copacabana and Leblon) are filled with sun worshippers, the colonial part of the city has many historic buildings and museums and the picturesque barrio of Santa Teresa is known as 'The Montmartre of Rio'. Its at night when Rio really comes alive though, with the samba bars of Lapa and the bars and restaurants of Ipanema and Copacabana filled with live music, energy and people having fun. The whole city goes wild with parades and parties in the week leading up to the Mardi Gras Carnival every year in February. The contrast between the opulent downtown and the poverty in the hillside favelas can be seen on a tour of Rocinha (the largest in South America). Another must-see attraction is a football game at the world famous 95,000 seat Maracena Stadium to experience the unique Brazilian football atmosphere. For quiet time away from the city's bustle, the beautiful Botanical Gardens or tropical rainforest of Tijuca National Park provides a welcome break from the concrete jungle.
