Londonderry
Londonderry is a small town in Rockingham County near the coast of the North Atlantic. It isn’t a primary diving hub, and there are no local dive sites within the city itself. The nearby freshwater option is Lake Ontario, but access and diving would be outside the town limits and region. For divers visiting New Hampshire and coastal New England, use Londonderry as a gateway to broader area attractions and services rather than a direct dive base.
