Mũi Điện, known historically as Cape Varella after the Portuguese name given by early maritime navigators, is a bold headland rising 110 metres above the East Sea at the northeastern corner of Phú Yên province. A working lighthouse has stood here since the French colonial period, and the cape remains an active navigation point for shipping moving along Vietnam's central coast.
Mũi Điện is traditionally described as the easternmost point of mainland Vietnam - a title that modern geographic surveys now assign to Mũi Đôi in Khánh Hòa - but what it offers is what Mũi Đôi cannot: a fully accessible cape by road, with panoramic sea views, a lighthouse with a history, and the adjacent Bãi Môn beach below. For the Vietnamese long-distance riding community, Mũi Điện remains the standard reference for the eastern extreme - accessible, dramatic, and at the furthest eastern reach of the main coastal highway.
