The Doble Islands consist of Cinta (the western island) and Docca (the eastern island). The capital of the islands is Grenanda. The islands' population is divided amongst four towns, with the capital being the biggest. The islands are both large, the largest in the state. Routes 21 and 70 connect the two islands. They also have a quick bus transportation system, travelling from Grenanda to Irving Point, and from Hightown through Sealshore, all the way back to Grenanda. Route 21 is a long road, connecting both islands, while Route 70 is a smaller road, leading near the coastline.
