To be honest its a 14-17 days trek and it requires initially the permission to go on the trek, because everybody cannot trek like this. Secondly, you must book a package or something like this because its one of the most difficult treks you'll ever be on , so prepare yourself and yes for safety, its april and yes i think, temperatures will be high as compared to earlier months. Happy Traveling !!!
