The Ospika Cones ecological Reserve was established in February 2001 to protect the Ospika Cones complex and the representative surrounding mountain slopes.
Accessible by helicopter only, and requires a permit.
“Calcium-rich springs are located on a bench-like flat area at the foot of the mountain slopes. Calcium deposits built up by the springs have formed a complex of colourful terraces and raised cylindrical spring pools which have become known as the “Ospika Cones”. As the lime-rich water warms when overflowing the rim of the pools and terraces it precipitates calcium which builds up natural dams. The highest of the spring pools is contained by a tall, circular limestone dam. The turquoise water of the deeper pools contrasts with the white, ochre and rusty coloured dams and cascading terraces. These formations are fragile, as evidenced by pools whose dams have been breached and drained of water.
