Under The Pier at Iboih Beach, Weh Island. Pantai Iboih (Iboih Beach), also known as Teupin Layeu, is located opposite the west bank of the legendary Pulau Weh, or Weh island, in northern Aceh, Sumatra’s most northern province. The town of Iboih, located on Pulau Weh is the most westerly point of Indonesia. Pantai Iboih (Iboih Beach) will bring your expectations of 'natural beauty' to a whole new level. This small, hidden paradise has remained largely untouched by much of the tourist traffic, giving it a more relaxed and laid back atmosphere. Its forests are well protected by Iboih's charming coastline of golden sands that is strewn with giant boulders. The shallow ocean water which is so clear that you can see the ocean bed, has a bluish-green hue which exudes a feeling of peace and relaxation.
