As the UK reels from the longest, coldest, grimmest winter since woolly mammoths roamed the streets of Chelsea, All 4 seeks to generate a bit of much-needed heat and bring the odd ray of sunshine to the nation with some cockle-warming (and the occasional spine-chilling) collections of box sets. Fearless Travellers takes us to the planet’s remotest corners, young things have fun in the sun, and some smash-hit sitcoms bring a warming smile to even the chilliest cheeks. And as night time falls, you can lose yourself in the darkness of Walter Presents’ serial killers collection.

Fearless Travellers – live March 5th

This month, All 4 brings you the world, in the form of four fabulous documentary series spread across the continents that paint a fascinating picture of 21st-century life in some of the far-flung corners of the planet. Each show is presented by a distinctive and unique character, who brings their own world view to these eye-opening travelogues.

Gaycation 
Openly gay actress Ellen Page heads out, with best friend Ian Daniel, on a journey to explore various LGBTQ cultures in locations around the world. Along the way, they meet people who share their stories of struggle and triumph as they work to be accepted by their communities. Their itinerary includes stops in Jamaica - notorious for its homophobia - and Brazil, where they experience one of the most dangerous confrontations of their lives in the country with the world's highest LGBTQ murder rate. On a lighter note, while in Japan they head to a party at the world's smallest gay bar.

Walking the Nile 
British explorer Levison Wood sets out to walk the length of the River Nile from source to sea in this epic four-part series. His nine-month, seven-million-step journey takes him through jungles, savannah, deserts, cities and war zones in some of Africa's most remote and spectacular locations. Along the way, he encounters modern Africa, its people and its wildlife face-to-face and at ground level.

Our Guy in India 
Guy Martin has a love for adventure and they don't come much bigger than an epic 1000-mile trip across India, culminating in one of the world's maddest bike races. Rider Mania is the largest gathering of Royal Enfield motorbikes on the planet. In this two-part series, Guy wants to ride there and win it at the end of his two-week trip. Along the way, Guy, with his love of tea, lorry repair, motorbikes and daredevil risk taking, introduces viewers to a rarely-seen side of modern India.

Escape to Costa Rica 
In this visually arresting three-part series, science writer and explorer Gaia Vince and her family go to Costa Rica to find out how this remarkable little republic has become 'the happiest, most sustainable country in the world'. Costa Rica runs its national grid on rivers and volcanos and by 2021 it will be carbon neutral. It has no military, and its rainforest is actually increasing and is home to more than 500,000 species. It is also, it must be said, somewhat easy on the eye.
