Matabungkay Beach is in Lian with a white sand beach reasonably accessible to Manila 120 kilometres (75 mi) that was originally 'discovered' to be a great weekend or daytrip destination in the early 1950s, allegedly by sun starved German residents of Manila. In fact the German Club had a cottage there then. It was soon a popular target for holiday-lovers and permanent cottages (even deluxe beach houses) were built along the beach line (and some into the beach) in the early 1960s by rich Manila folk.
