Rara lake Tour by flight is the best and easy way to explore the lake. You can fly from Kathmandu towards Nepalgunj Airport and then stopover for a night and fly towards Talcha Airport which is located in Mugu. Once you reach the airport, you can hike towards to lake which takes approx 2 hours to reach.
Explore the lake and the natural beauty of Rara Lake and spend a couple of nights there. Then again hike back to the airport and fly back to Nepaljung. Only a small 16 seater plane from Nepalgunj to Talcha so small groups are recommended for the Rara lake tour by flight.
