Do we have access to water on the ascending towards the summit?

There aren’t any water fountains to drink or have a fill-up on the way.  You will have access to water between the second (Gusfand Sara) to the third camp ( Bargah Sevom).  On the third camp (Gusfand Sara) you can buy mineral water. There you will a water spring, which is reserved for cleaning which may not be suitable for drinking.
