The peninsula's geology makes swimming treacherous but tide-pooling exceptional. At low water, the exposed rock shelves reveal miniature ecosystems: anemones retracting their tentacles, hermit crabs jousting over vacant shells, small octopi changing color in the shadows. The pools themselves range from bathtub-sized to small ponds, each with distinct temperature and salinity depending on sun exposure and connection to the ocean.

The rock formations here tell volcanic stories—columnar basalt in hexagonal patterns, smooth pahohoe flows frozen mid-drip, and jagged a'a where boots find questionable purchase. Storm swells funnel into narrow channels, creating compression waves that shoot upward in geysers. The sound is constant percussion: waves slapping stone, rocks tumbling in the undertow, water draining through crevices with sucking hisses.
A rough footpath follows the coastline, requiring attention to footing and tide tables—sections disappear entirely at high water. You'll pass fishing platforms bolted into the rock where locals cast for rockfish and greenling. The views extend south toward distant headlands and north to where the peninsula's spine rises in forested ridges. No services, no railings, no warnings beyond what common sense and the ocean's obvious power provide.
