A quick ferry ride from Fukuoka, pretty Nokonoshima (能古島) mixes natural and man-made parks. The latter, called Island Park , gets the most visitors, with a swimming beach, fields of seasonal wildflowers, huts selling crafts, and sweeping ocean views.
Bicycle rental (per hour/day ¥300/1000) and English maps are available at Noko Market (のこの市), by the ferry dock. Buses 300 and 301 depart frequently from Nishitetsu Tenjin bus terminal (¥360, 20 minutes) for Meinohama Municipal Ferry Port (not to be confused with Meinohama on the subway line).
