Achham is one of the remotest districts of Nepal. It is accessible by automobile from Kathmandu and Nepalgunj via a paved road that runs along the western border of Nepal from Dhangadhi. The unpaved road of Mid-Hill Highway through Dailakh district also traverses to Mangalsen by crossing Karnali at Rakam.

Mangalsen, the district headquarters, is an eight-hour walk and a 2.5 hour drive from Sanphebagar – a town in Achham sporting a non-functional domestic airport. A bridge crosses the Budhiganga River in Sanphebagar allowing access during high water, a second bridge over the Kailash River. During 2009/2010, the government of Nepal has constructed a paved road connecting Sanphebagar to Mangalsen. The district is served by two hospitals, the government district hospital in Mangalsen and one recently opened in Bayalpata named Bayalpata Hospital that is a collaboration between the government and the non-profit organization Nyaya Health.

71% of men aged five and above are literate in Achham compared to 75% at the national level, only 43% of such women in the district can read and write (against 57% across Nepal).
