One of the better beaches in New Taipei City (this is not meant to be particularly high praise) is found at this little bay, the name of which translates as 'white-sand bay' – though these days it is definitely more of a brownish colour. The entrance to the beach is down a side road 100m or so off Hwy 2 (there are brown signs in English around the 23km mark). Swimming is permitted from May to September, as is surfing. For surfboard rentals and lessons, visit CU Surf Paradise Taiwan on the main road where the bus drops you off.
Baishawan is formed by the stubby finger of rocky Linshanbi Cape (麟山鼻, Línshānbí) extending into the Taiwan Strait. This is a scenic part of the north coast and a several-kilometres-long boardwalk runs along the shoreline as part of a 10km bike path from Sanzhi to Shimen.
Tourism Shuttle Buses from Danshui MRT station stop on Hwy 2 just before the entrance. Or catch bus 862 (20 to 30 minutes, every 20 to 40 minutes) heading to Keelung. The first bus leaves at 5.50am. Check the stop at Baishawan for the return schedule (there should be return buses until around 8.30pm).
