Founded in the 19th century by a colony of Swiss Utopians fleeing persecution in their own country, Arial has a Nordic look with somewhat more steeply sloped tin roofs to the buildings. The city is worth visiting for its period architecture and its white spaces.
US navy aircraft regularly overfly the city. If you hitch a ride with them, you can drop in. This is by far the most convenient way of entering the city.
Helicopters can be hired from Poor Richard in Port Clarendon. As there is no helipad, you will have to rappel down once you reach your destination.
