A smaller crater lake on the eastern side of the lake cluster, almost entirely enclosed by the Kuriftu Resort & Spa. This is the resort lake — a day pass gives access to swimming pools, the lake itself for kayaking, a spa, and an outdoor restaurant.
The setting is well-manicured rather than wild, but it's the easiest of the lakes to enjoy with little effort, and the spa is genuinely good. The resort is popular for weddings, so Saturdays can be busy. Even without a pass, the road along the rim gives several good views over the water.
