Photo: GetYourGuideSee the very best of the valley in a single guided day, taking in all seven UNESCO World Heritage monuments including Boudhanath, Pashupatinath, Swayambhunath and the three Durbar Squares of Kathmandu, Patan and Bhaktapur. A private or group option, with lunch and entry tickets available, and pickup from your hotel. It is a lot of ground, so the comfort of a car and guide really pays off. Book the version with entry fees included to skip ticket queues at each site.
