Siuna is a county-sized administrative municipality in Nicaragua, located approximately 318 kilometres (198 mi) northeast of the capital city of Managua and 218 kilometres (135 mi) west of the coastal city and regional capital Puerto Cabezas in the North Caribbean Autonomous Region (RACN).

Most were settled in support of gold mining along the Ei River drainage basin, leading to rapid population growth from the mid-1930s.

There was migration from other areas of the country to work in the gold mine during those years, including people from the coast and indigenous groups.

HEMCO is also active in Siuna through the Javier Chamorro Forestry Project working through Norwegian teak grower NORTEAK.

The following government institutions are present and working in Siuna: MINSA, MARENA, INTA, INAFOR, and as well as the SILAIS office for the RACCN.

The majority of the population today are farmers after the closing of the regional gold mining operations.

In addition the approach focuses not only on construction of projects but of exchange between people and cultures through service learning and reflection.

The bus from Managua to Siuna takes 12 hours through Rio Blanco on the Puerto Cabezas road.
