Calling all adventure seekers

Are you a trail runner looking for a new adventure? Or an experienced hiker who like to travel fast and ultra light? We organize small groups of active people who want to get way off the beaten path in the Himalaya.

Come adventure with us

You can trust our years of experience helping people safely explore high altitudes. Let us safely handle all of the logistics so you can focus on making lifetime memories. Our fastpacks are 10-12 days long and include safe acclimatization schedules, experienced guides and risk management strategies. Travel at your own pace with a mixture of walking, power hiking, and running if the spirit moves you. Travel with only the bare essentials so that we don’t have to rely on porters or pack-animals to carry our gear. Read more ‘Why Himalayan Adventure Labs?’

You can count on us

Excellent logistics including being collected on arrival at the airport and dropped off at end of trip. Super fun team and diverse itinerary which included some trails that are not part of the official circuit. Great food, laughs and team dynamic. Challenging course meant greater level of satisfaction on completion of each stage. Highly recommend.
