To be the very first climber to step foot on any summit could be regarded as one of the holy grails of mountaineering. But it’s not just the stuff of history books: incredibly there are still many more unclimbed mountains than climbed ones.

Test your limits

Every year, pioneering mountaineers are pushing their limits and rewriting the annals of climbing. We can assist you to do the same, even help when choosing the objective. We’re setup to lead everything from scouting expeditions, strategy, securing permits, logistics, all the way to those final steps to the summit, and of course safe passage back down to base camp.

The shear vastness of the well explored Himalayas offer many summits still to claim

These high altitude first ascents are for mountaineers who have already developed and proven their skillset on the well-trodden path, but feel like they want more from their endeavour, a desire to reach somewhere no one has been before them.

At Nimsdai expeditions we recognise that impulse, that drive. We feel it too. And we’ll share it, along with our vast experience of climbing the world’s most challenging peaks. Let us help you take your skills into the unknown. And into the history books.


For many mountaineers, opening new routes is on a par with a first ascent. In fact, it’s often more challenging. So, in years to come what will be the achievements that define your climbing career?

Make it yours

If you thrive on blazing new trails, yearn to unpick the mountaineering problems that have overwhelmed generations before and have the mindset to push yourself beyond your limit, then opening a new route is probably already in your mind.

The fact you are even contemplating this probably means you’ll already be well versed in many of the skills required and have an understanding of the many vital components to overcome such a challenge. That’s where Nimsdai Expeditions fits in; to tie it all together. We’ll embrace your objectives, build a solid plan and team around it and make all the key decisions when it matters, whilst continually balancing safety alongside the success of the expedition.

Your defining mountaineering achievement may be closer than you think.

Why choose


Nims (leader on all expeditions) is a multi-world record breaking mountaineer, the fastest to summit all 14 8000m peaks. He has led 20 x 8000m expeditions with a 100% success rate, in both reaching the summit and more importantly bringing everyone home safely. Combining this with his UK Special Forces and Ghurkha heritage, he is the perfect bridge between Western and Nepalese cultures, providing an invaluable local Himalayan infrastructure and a totally unique skillset fine-tuned for success in the mountains. This is reinforced with a world class team of Sherpas hand-picked by himself through a process similar to the rigorous demands of special forces selection, all operating together with shared principles and code of conduct.

Safety through

If it’s controllable we control it, this is key to attain and maintain our industry leading strategy for success and safety. We maximise our options, agility and responsiveness by running totally self-sufficient expeditions, not relying on any other teams on the mountain to achieve our objectives. We are capable of setting up our own fixed lines (with a proven track record on all 8000m peaks) and have backups to cover all scenarios, from secondary oxygen supplies through to the ability and experience to operate our own rescue missions if the situation arises.
