Physically demanding, the trip takes in some of the highest motorable passes in the world, with the Khardung La at 5,328 metres being the highest, meaning altitude acclimatisation is essential.

The rough roads mean gravel or mountain bikes are best, or even a touring bike is also feasible. Basic accommodation is available along the way, but if riding unsupported it’s best wise to have a tent in case the weather turns.

When to ride: June to September.

Lanna Kingdom, Thailand

Chiang Mai in northern Thailand has long been known as the region’s cycling hotbed. The mountainous region to the west and north of the city is a wild and rugged place.

The issue has always been in finding these unmapped routes that wind through local villages, until last year that was, when the 393km Lanna Kingdom Bike Packing route was pinned together, which makes for a great off-road adventure that can take as many as 10 days.

While there is accommodation along the way, you may well need a tent for a couple of nights. So, not necessarily one for the beginners.

When to ride: There are two seasons when the route is passable, October to early February and May to June.

The Four Rivers path, South Korea

The 633km Four Rivers route runs right across South Korea. Starting from Ara Lock near Seoul, it heads south to Busan and has become the country’s most prized bike touring route.

Created to revitalise the country’s four main rivers, the route is mostly on well paved roads, with some short rough sections and a few small hills thrown into the otherwise flat mix.

It takes between a week and 12 days for most to compete, and there are many accommodation and camping options along the way, making it perfect for all levels of cyclist.

When to ride: Between September and November.

Northern Pakistan

Pakistan’s northern Himalaya regions are some of the most spectacular and culturally rich places on earth, where you will you find 8,000m peaks towering above you, open high plateaus, lush and barren valleys, huge lakes, and unique cultures.

Naturally, this makes for of the most challenging and rewarding off-road bike travel adventures too, all on real world trails that can make for the journey of a lifetime.

There are countless route options in the area, rides that venture way beyond the well-ridden Karakorum Highway. The section crossing the Deosai Plateau from Skardu to Chilas, and then continuing on to Gilgit is particularly impressive.

When to ride: Late June to late September. Bring a tent

The Ha Giang Loop, Vietnam

Vietnam’s mountainous far north has become a prime destination for adventurous and fit cyclists, with the 300km Ha Giang Loop one of the favourites.

From Ha Giang to the northwest of Hanoi, the route winds through the steep sided mountains, and includes around 7,500m of elevation gain.

The scenery in the area is awe inspiring, and you will pass through many rural and ethnic villages along the way, making it a cultural adventure as well as a challenging ride of between five and eight days.

When to ride: September and October are perfect for seeing the region’s golden rice fields in bloom, while February to March is spring blossom time.
