Highway 11: Where the Mountains Meet the Pacific
Highway 11 runs where Taiwan's Central Mountain Range meets open ocean with almost no coastal plain in between — a genuinely different geography from the island's west coast, and the reason this drive feels more like a mountain road with sea views than a beach highway.

Why there's no coastal plain here
Taiwan's east coast sits directly on the same tectonic collision zone responsible for the island's mountains generally, but here the uplift happens close enough to the shoreline that the mountains simply haven't had room to erode into a gentle plain the way they have further inland — the Central Mountain Range drops close to straight into the Pacific across long stretches, leaving Highway 11 to hug a narrow shelf between cliff and water rather than run through open coastal farmland. That's the structural reason the drive itself is the attraction: headlands, rocky coves and sudden beaches replace the kind of long straight coastal stretch found on gentler shorelines.
Sanxiantai's eight-arch bridge and Shihtiping's carved rock
Sanxiantai's footbridge — eight arches connecting the mainland to a small offshore island and its lighthouse — was built specifically because the island itself has no natural land connection, its rock having separated from the coast through the same wave erosion still visibly reshaping the shoreline around it today. Shihtiping, further south, shows that same erosion process from a different angle: flat-topped volcanic rock formations and tide pools carved by wave action into a stepped, terraced pattern distinctive enough to have given the site its name, which translates roughly to “stone step plain.”
Green Island: a volcano reached by ferry
Green Island, reached by ferry from Taitung, is itself volcanic in origin — its clear water and coral growth are a direct product of that volcanic seabed, and its own hot springs (genuinely rare as a seawater-fed hot spring, one of only a handful in the world) tap the same geological activity that built the island in the first place. The combination of diving, snorkelling, hot springs and a compact cycling loop around the whole island makes it a natural extension of an east-coast trip rather than a separate destination requiring its own dedicated planning.
