On Wednesday, His Majesty the King of Bhutan officially declares the Trans Bhutan Trail open to the public.
At a ceremony in Thimphu, the first international hikers on a sold out itinerary by operators G Adventures will receive a special welcome to the notoriously hard to visit destination.
A 400km route through the mountain Kingdom, past cliffside monasteries and Himalayan forests, unseen by western tourists for over 60 years, it is a moment adventure travellers and trampers across the world have been waiting for.
It's got all the ingredients for a blockbuster fantasy film, never mind a world-class multi-day hiking trail.
Leading into the East, and away from the traditional tourism centre for Bhutan, the TBT promises to take trampers to places nobody has been for half a century.
Opening up new areas in a country that is famously strict on its admission to international tourists, the clearing of the ancient pilgrimage route is just as important as a cultural milestone for the Bhutanese Kingdom.
The 500-year-old mountain route is an artery that bisects the country, East to West. As a messenger and trading route, until the 1950s it was the only 'highway' for foot traffic connecting the disparate regions of the mountain country.
That was until the construction of the main roads and the introduction of new transport. Bypassed by motor traffic the mountain routes quickly fell into disrepair, leaving them unused for the best part of six decades.
When, founder of the Bhutan Canadian Foundation, Sam Blyth first came to the country in the 1980s, only the oldest of residents remembered walking the path as children.
"I'd always heard of this legendary trail and experience, because it had a big impact on very young children," he said in a statement.
Having worked with the kingdom on restoring the route during the pandemic as a method of stimulating jobs for 900 furloughed tourist workers and others, it has transformed the outlook for tourism in the country.
They installed over 10,000 steps and 18 footbridges through the mountainous terrain.
