The island Solarte is a medium sized island south of the much larger Isla Bastimentos. The island has a limited population mainly living in small communities along the coast.

Its southern coast is lined with mangroves and multiple mangrove islets, making it difficult to land. But once on the island and past the mangroves, the primary forest takes over. Solarte is dominated by primary lowland rainforest that consists of large emergent trees such as Fig trees (Ficus sp.) and Almendro trees (Dipteryx oleifera). Understory growth is relatively sparse with the majority of undergrowth consisting of Dieffenbachia, Calathea, small palms and Heliconia. It is on the undergrowth that this population of Oophaga pumilio is found, on or near tree bases. The frogs were never located directly in or on leaf litter as they used branches and roots to travel across the ground.
