Amazon

Beneath the canopy of the rainforest lies one of the most packed and diverse ecosystems on the planet, making it an eye-opening voyage for nature lovers.

The Amazon has the widest range of bird and tree species in the world, while the rainforest reserves make for excellent wildlife viewing.

You'll get the chance to see animals you've never seen before in their natural environment, such as monkeys, sloths, dolphins and many, many more.

But you don't have to be an expert to appreciate the environment, as experts will be on hand to share their vast wealth of knowledge with travellers.

The experienced guides know just where to look to find the most fascinating sights.

But don't start fearing that you have to rough it in the wild for days on end - travellers can roam the river in fine accommodation, eating the finest foods and enjoying a relaxing yet stimulating experience.

With a climate and environment that's totally different from home, it really does feel like a voyage of discovery as you navigate your way through one of the treasures of the world.
