Located south-east of Isla Sorna, the mountainous Isla Tacaño is the second smallest island in the Muertes Archipelago, dominated largely by peaks and highlands. Although InGen was not known to operate a facility on Isla Tacano, Costa Rican fishermen were apprehensive about the entire island chain. In the 1980s, the islands of the Muertes Archipelago, including Isla Tacaño, were purchased from the Costa Rican government by InGen, in a 99-year lease which also covered the neighbouring Isla Nublar to the east. Thankfully its weather is calmer than some of the other islands. This island is infamous for its rugged terrain that makes construction near impossible in many regions. There was an attempt to start up operations here before. It lies between Isla Sorna and Isla Pena. Isla Tacaño is the second-smallest island in the Cinco Muertes Archipelago.
