Formed by a cataclysmic volcanic eruption around 70 000 years ago, Lake Toba on Indonesia’s Sumatra Island is the largest volcanic lake in the world. This picturesque lake surrounded by towering mountains serves as a popular getaway for travellers looking to escape the chaos of the modern life. The main attraction is simply relaxing on the shore and swimming in the mineral-rich waters of the lake. Those looking for a bit of action can head to Samosir, an island in the centre of the lake which features an array of guesthouses, restaurants, cultural centers, and bars. Don’t miss the Museum Huta Solon Simanindo, showcasing the traditional culture of the local indeginous Batak tribe; and the 300 year old stone chairs at Ambarita village, believed to to be remnants of an ancient criminal court.
