Even though the altitude in Bhutan is higher than most people are used to, altitude sickness is rare in Bhutan as most valleys are under 2,500 metres, and mountain passes are generally only just over 3000 metres. Our cultural tours do not reach altitudes higher than 3,500 metres (except the ‘Journey Across Bhutan’).
Our entire range of trekking programs reach an altitude of a maximum of 3,500 metres, with some going as high as 5,000 metres. It is recommended that visitors avoid any trekking or climbing until at least day 3 of their itinerary unless they are moderately fit and do not suffer from any lung related condition such as asthma.
If you have concerns about experiencing altitude sickness during your visit to Bhutan, we suggest that you carry Diamox which can be taken in advance as a precaution.
If you suffer from severe altitude sickness during a trek, please advise your trek leader as soon as possible, begin descending form your current altitude and drink plenty of fluids. Diamox (Acetazolamide) maybe combined with Ibuprofen or paracetomol after commencing treatment symptoms may last for a few days.
