The bottom line
The Ijen Geopark Run is arguably the most dramatic setting in the Geopark Run Series: the course starts at Paltuding Camp, the base camp for Mount Ijen — the volcano famous for its electric-blue sulfur flames and turquoise crater lake. Three distances (21K, 10K, 5K) with registration open. The highland setting (roughly 1,800m at the crater rim) means cool mountain air — a world apart from Indonesia's coastal races. August is the dry season in East Java. For runners wanting an Indonesian half marathon with genuine volcanic scenery, this is a bucket-list pick.
Mount Ijen: The Blue-Fire Volcano
Mount Ijen is one of Indonesia's most extraordinary natural wonders — a volcano with an electric-blue sulfur flame visible only at night, and a turquoise crater lake that's the most acidic in the world. [1] Paltuding Camp sits at roughly 1,800m, providing cool highland conditions. The Geopark Run Series (backed by Indonesia's Ministry of Tourism) handles production.
