Pokhara I famous as the lake city, do not forget to enjoy boating. The reflection of Annapurna mountain range over the lake you are boating makes your tour a lifelong memorable. Have your dinner by the lake or spend time around the lake.
Most of the days will be busy with scheduled tour activity; however spending time at Mayadevi temple in Lumbini and spending evening at Pashupati Temple during Kathmandu tour will be interesting.
