Annapurna region.
You see 23 big mountains from Khopra Ridge.
… 3 are amongst the 14 highest mountains in the world – Mt Manaslu (8th highest), Mt Annapurna I (9th highest) and Mt Dhaulagiri I (7th highest) …
It costs about $500 for 8 days to join an IndiaHikes guided tour to and from Pokhara. Everything included. Accommodation and meals at teahouses.
Sounds GREAT to me.
