Everydody knows there are 8 wonders of the world. Nayogarra for the waterfalll, Pyramid in Egypt and Great Wall in China but nobody knows Rara Lake is one the rare wonder of the indiviual world. Niether it is virtual vision nor artificially made. This is natural and untouched by human hand even a side of the Lake Rara. So, Nepal has more wonderland!!!
Veraties of Pines forests, Leopards, Tiger, Bears, Red Pandas, Rhododendron, wide and unvealed pastures and himalayan trouts in the Lake blow on mind! Rara National Park covers the area- probably the smallest national park of Nepal. September, October, November in autom is the best moment to go and March, April and May is the best time in spring season.
Better idea to take an aeroplane from Kathmandu to Nepalgunj the, again you can take another flight to Jumla if you have more time (12/13 days for roudn trip) and fly to Talchha airport from Nepal also well recommended. Otherwise, by land transport neccesserily by taking a flight KTM to Nepalgunj, then another option of transport. But remember it takes longer time by land as the road is even not graveled one!
