Officially, there are no deaths recorded during the Annapurna Base Camp trek. However, there have been deaths in the past due to natural disaster such as avalanches during the pre-spring season and landslides during the monsoons. On the ABC trail, there is a section above Deurali where trekkers need to take heavy precautions. Also, it is advisable to take information before crossing the section which is a notoriously dangerous zone especially during pre-spring and rainy seasons.
