The Kilauea volcano in the Kahaualea Natural Area Reserve on Hawaii's southernmost island is one of the world's most active volcanoes, boasting 61 eruptions since 1823. Its current eruption has been ongoing since 1983, and has produced 3.5 cubic kilometers of lava. We can't help but feel that a road in this area was not the best idea.
It looks unassuming, but the Frontier Closed Area, designed to prevent illegal immigration from China into Hong Kong, is closely guarded and controlled. Visitors are not allowed through without a permit.
Midway Atoll, true to its name, is in a remote location in the North Pacific Ocean about midway between North America and Asia. Although it's officially a U.S. territory, it is both unorganized and unincorporated. It's a wildlife preserve and a UNESCO World Heritage site. Aside from its remote location and limited outside access (permits are required), it should be quite obvious why Google Street View could not travel any farther along this jetty.
