The southern edge of the small coastal town of Daxi has a small surfing beach known as Honeymoon Bay. Waves are generally chest to head high, though during the summer typhoon months they can be over 3m high. Depending on the swells, conditions are suitable for beginner to advanced surfers. As at other popular surfing venues you'll find board rental, and shops selling food and drink around the beach. Turtle Island lies to the southeast of the crescent-shaped bay.
Daxi is also the end (or start) of the Caoling Historic Trail. The trailhead begins just north of town after you cross the bridge over the Daxi River.
There's an hourly train from Taipei (NT$101, 1½ to two hours). When you exit at Daxi, cross the road and walk south about 600m along the sea wall to reach the beach.
