How do you celebrate fifty years of trekking the world’s greatest mountain valleys?  With a giant party of course.

The crew at World Expeditions have launched seven birthday treks in Nepal in September 2025 with all guests converging together in the spiritual heart of the Khumbu Valley, Thyangboche, for one hell of a black tie event with Everest as a backdrop.

Trek for anything from 13 to 30 days in the region and immerse yourself in stunning landscapes with the world’s tallest peaks and turquoise lakes, through Sherpa villages and yak pastures. Stay in Eco Campsites and Eco Lodges, with all meals included as you’re guided by the world’s best.

Fancy trekking with Australia’s most esteemed mountaineer, Tim Macartney-Snape? The first Australian (alongside Greg Mortimer) to reach the summit of Everest, Tim climbed without supplementary oxygen, via a new route on the North Face forty years ago in 1984.

Join him for a 16 day adventure with a mix of wilderness camping and Eco Campsites and lodges in the Khumbu Valley, finishing this exciting expedition in time for the 50th birthday banquet of a lifetime with trekkers from around the globe.

Short on time? Take the 50th Anniversary Everest Trekking Tour, an introductory 13 day trek with views of Everest, Ama Dablam, Lhotse, Nuptse and surrounding Himalayan peaks.

Check out all the treks on offer here, and pack your Sunday best with your trek boots for the party of a lifetime.
