Infrastructure makes it difficult for tourists to travel independently and costs of private tours are high. Since the re-opening of the train line from Addis Ababa to Djibouti in January 2018, travel by land has also resumed. Djibouti's two main geological marvels, Lake Abbe and Lake Assal, are the country's top tourist destinations. The two sites draw hundreds of tourists every year looking for remote places that are not visited by many.
