Katmandu, Bhaktapur Patan, and another locals city I forgot the name ( Themi) are the most interesting cultural cities for sightseeing in Katmandu valley. It's a very very vibrant and tremendous and much rich culture in Nepal. I went to Pokhara and on the way rafting in the river was great fun. 8 days of trekking to Khopra's dada was awesome and amazing with the fabulous horizontal mountain view of Dhaulagiri, Annapurna series. After the trek, I went to Chitwan for 3 days Jungle Safari and back to Kathmandu via a flight.  I am very thankful to my guide and the organizer Sabbatical Explore Nepal for the best trip arrangement even for a short time. As we have discussed at the farewell dinner together I am sure to be back with my other working colleague. 
I already miss the beautiful mountains and caring people of Nepal. Specially Shiva my guide Shesh.
Namaste ! and see you asap !!
