Dulombi is situated around the junction of Gabú, Bafatá and Tombali Regions in the central-southern part of the country. The southern border of the site is formed by the international frontier with the Republic of Guinea between the towns of Contabane in the south-west and Boé in the south-east. From near Boé the boundary runs northwards along the course of the Rio Corubal to just west of the town of Ché Ché then westwards almost as far as Xitole and so south towards Contabane. The park is drained by the Rio Corubal which flows through it and forms part of the eastern boundary. Vegetation is comprised of dry, sparse woodland, patches of dense woodland and stretches of gallery forest. Mean annual rainfall is 1,500 mm.
See Box and Table 2 for key species. A total of 164 species have so far been recorded from the site, which has yet to be thoroughly surveyed. In addition to those listed below, eight species of the Guinea–Congo Forests biome (A05) have been recorded (see Table 2).
