West of Lumbini, Nepal changes pace. Tourist numbers fall away, hotels thin out and the country opens into some of its least visited land: the Terai grasslands of Bardia and Shuklaphanta on the Indian border, the pine-covered hills of Karnali and Sudurpashchim provinces, and Humla, the roadless district that touches Tibet. Nepalgunj, at 150 m and 6 km from the Rupaidiha border, is the hub. Almost every trip here starts with an hour's flight from Kathmandu to Nepalgunj or Dhangadhi, or a drive across the border from Lucknow.
Bardia National Park, 968 km² of sal forest and grassland on the Karnali river, is the reason most visitors come. Nepal's 2026 census counted 112 tigers there, and the park's full-day jeep and walking safaris, run from the Tharu village of Thakurdwara, give patient guests a real chance of seeing one without a queue of vehicles. Further west, Shuklaphanta holds 50 tigers and Nepal's largest herd of swamp deer on open phanta grassland. Both parks are at their best from February to April, when the grass has been cut and the water shrinks.
In the hills, Rara Lake is the headline. Nepal's largest lake, 10.8 km² at about 2,990 m, sits in a ring of blue pine in Mugu district and is reached by a 45-minute flight from Nepalgunj to Talcha or a 5–6 day trek from Jumla over passes near 3,600 m. Khaptad National Park, a plateau of meadows at about 3,000 m, and the small lakes of Ramaroshan offer quieter walks from the Dhangadhi side, with views of Api and Saipal on the skyline.
Humla is the far end of the map. Simikot, its headquarters at 2,910 m, has no road link to the south and is reached by small plane from Nepalgunj. Kailash pilgrims pass through on the helicopter route to Hilsa, and trekkers continue up the Karnali to the Tibetan Buddhist villages of the Limi Valley, crossing Nyalu La at about 4,950 m. Lodges here are basic, flights depend on the weather and treks need permits and full camping support, which our packages arrange.
