beig serious - foreign tourists stopped going to swat when the hippy trail from europe came to an end and with the russian invasion of afghanistan and iranian revolution. The overland route was blocked so there was a shrp drop in tourists.
since then swat has never been a hit with foreign tourists. its nt because of terrorism alone its because theres far too many domestic tourists in swat and muree which foreigners find off putting. chitral, hunza and gilgit get the bulk of foreign tourists in the north. most other areas are avoided.
