About Geothermal Goldfish Pond
Geothermal Goldfish Pond, Iceland is a small natural geothermal pond located approximately 2 kilometres south of Húsavík in North Iceland, tucked off Route 85 among the Kaldbakstjarnir lakes. Also known in Icelandic as Yltjörn, or informally as Kaldbakur pond, it is one of four ponds in the Kaldbakstjarnir group, but the only one fed by geothermal water. Its temperature ranges from approximately 20 to 30 degrees Celsius depending on the season, making it warmer than a standard Icelandic pond but considerably cooler than most purpose-built hot spring pools in the country.
The pond's name comes from its inhabitants. At some point, local residents released unwanted pet goldfish into the water, and the geothermal warmth of the pond has allowed them to survive and breed through Icelandic winters, when the surrounding landscape is frozen solid. The goldfish population is considered one of the most northerly in the world. The combination of geothermal mist rising off the water, snow on the ground, and bright orange goldfish visible just below the surface is a genuinely unusual sight, and one that draws curious visitors as much as soakers. Local children from Húsavík are known to visit with nets in summer to catch and release the fish.
The pond is one of the more distinctive natural pool settings near Húsavík and sits within easy reach of the Diamond Circle, the scenic loop route of major natural attractions in Northeast Iceland. Visitors already stopping at GeoSea sea baths in Húsavík, Ásbyrgi Canyon, or Goðafoss waterfall can easily add a brief detour here without significant extra travel. The pond is not a geothermal pool in the sense of a hot soaking spot: the temperature is best suited to summer days and does not provide the heat-based soaking experience of higher-temperature pools found elsewhere in Iceland.
Location & Access
Getting to Geothermal Goldfish Pond
Geothermal Goldfish Pond is reached by driving south from Húsavík on Route 85. After approximately 2 kilometres, before fully leaving the town's southern edge, a gravel track branches off to the right toward the Kaldbak cottages. Follow this track a short distance, pass the cottages on the left, then turn left at a visible dusty road. This path leads around the Kaldbakstjarnir ponds. The geothermal pond is opposite the entrance to the main Kaldbakstjarnir lake area. The approach is straightforward in dry summer conditions; the gravel track may be muddy after rain or in shoulder seasons.
The site is also reachable on foot from Húsavík. Walking south along Route 85 takes around 20 to 30 minutes to reach the junction. The route is flat and follows the road before turning off onto the gravel track. The pond is hidden from the road by a slight rise in the land, so it is not visible until you are very close. Rising steam from the water is the most reliable sign you are near the right spot. It is worth noting that the three cold ponds of the Kaldbakstjarnir group are larger and more prominent than the geothermal pond, and it is easy to reach one of these first and mistake it for the destination. The geothermal pond is the smaller, steaming one across from the main lake entrance.
There is no car park, no signage, and no formal infrastructure at the site. Visitors park on or beside the gravel track. There are no facilities of any kind: no changing rooms, no toilets, and no management. This is a fully unmanaged natural site. For those looking for hot springs near Húsavík with a more developed setting, GeoSea sea baths are located less than 1 kilometre from the town centre and offer full spa facilities using the same type of geothermal water that characterises this region of North Iceland.
Suitability & Accessibility
Who Can Visit Geothermal Goldfish Pond
Geothermal Goldfish Pond suits curious visitors of all ages who want to see a genuinely unusual natural phenomenon, particularly families with children who may enjoy the goldfish and the informal atmosphere of the site. The approach is flat, the distance from the road is short, and no hiking equipment or physical preparation is required. The pond itself is shallow enough for supervised wading, and the temperature range of 20 to 30 degrees Celsius is accessible for children without the overheating risk posed by hotter pools.
The site is not a formal hot spring soaking pool. The water temperature is on the cooler side of what most visitors would consider comfortable for extended bathing, particularly outside the height of summer. In cool or overcast weather, or from September through May, the water may feel too cold for comfortable immersion. Visitors who want a reliable soaking experience rather than a curiosity visit are better served by GeoSea in Húsavík or other higher-temperature pools in the region. For those seeking free hot springs in Iceland with an unusual character, the goldfish pond offers something genuinely different from any other pool in the country.
Wheelchair access is not possible. The gravel track and the uneven ground around the pond are not adapted for mobility aids. The pond edge is natural and has no entry steps, handrails, or level access. Visitors who need mobility assistance should not plan on reaching the water's edge. There are no facilities on site for any visitor. Clothing optional means that in this fully unmanaged outdoor setting there are no rules about swimwear, but visitors should use common sense about changing outdoors given the site's proximity to the road and the cottages.
Safety & Etiquette
Safety and Etiquette at Geothermal Goldfish Pond
Geothermal Goldfish Pond is a safe site to visit in the sense that the water temperature is moderate and presents no scalding hazard, but it is an entirely unmanaged natural pond with no oversight, no emergency facilities, and no maintained infrastructure. The absence of any management means that conditions on arrival depend entirely on the natural state of the pond at that time. The water contains algae, aquatic plants, and the goldfish population, and the pond floor is natural and uneven. A layer of pond scum on the surface is common, particularly in summer when algae growth increases, and the floor can be slippery underfoot.
The temperature of 20 to 30 degrees Celsius is not high enough to present a heat hazard under normal circumstances, but it is also not warm enough to be comfortable for long periods in cool or windy weather. In autumn and winter the water temperature drops toward the lower end of the range and immersion will feel cold rather than warm. Midsummer visits on still, sunny days offer the best conditions for bathing, as the air temperature and water temperature together create a reasonable soaking environment. In any other conditions, most visitors use the site for looking at the goldfish rather than swimming.
There are no facilities, so all visitor waste must be taken away. The site lies beside private cottages and is adjacent to the Kaldbakstjarnir birdwatching area, which hosts species including Horned Grebe and Red-breasted Merganser. Visitors should keep noise low, avoid disturbing nesting birds in the broader lake area, and stay on the established gravel track rather than crossing open ground toward the main lake. If you catch a goldfish, release it back into the pond. Removing the goldfish is contrary to the spirit of the site, which has functioned as a de facto wildlife pond for decades.
The gravel access track can become muddy after rain and may be passable only with care in wet conditions. The track and surrounding ground are soft in places, and cars should not be driven off the established surface. Route 85 runs past at normal road speed, so take care when parking and when walking back to the road. The pond is located on or near private land associated with the Kaldbak cottages; visitors should respect the surrounding property, stick to the access route, and not treat the area as a campsite or picnic ground.
