Taking people on extraordinary adventures for years.

Arnold Coster Expeditions is a small boutique adventure company run by the owner Arnold Coster himself. Arnold is probably the most experienced leader in the Himalayas at the moment and has more than two decades of leadership experience. He led close to 100 climbing expeditions in the Himalayas and other greater ranges!

We don’t advertise with catchy slogans, questionable success rates or flashy videos claiming to be the best. We have been around long enough to know what we offer; good value for money with responsible leadership! Arnold learned his experience the hard way and is happy to share this experience with anybody. When you contact Arnold Coster you will immediately notice his down to earth mentality and this is how we run our trips also.
