Heidmork Forest
Heidmork is an extensive nature reserve situated on the southeastern outskirts of Reykjavik, officially established and inaugurated in 1950. Spanning approximately 3,200 hectares, it serves as the primary outdoor recreational hub for the inhabitants of the capital region. The reserve is best known for its highly successful long-term reforestation program, which has seen more than four million trees planted since the 1950s, a major achievement in the Icelandic landscape. Beyond its forested areas, Heidmork contains significant geological features such as Rauðhólar, a cluster of striking red pseudocraters formed about 5,200 years ago during a lava flow. The area also acts as a critical protection zone for Reykjavik's municipal water sources, ensuring a supply of pure drinking water under strict environmental regulations. It features a network of over 40 kilometers of maintained trails for hiking, mountain biking, and horseback riding. The flora is exceptionally diverse, featuring various conifers, birch, and extensive moss-covered lava fields.
