Husafell, Hraunfossar and Deildartunguhver

This West Iceland day trip in the Borgarfjordur region combines lava-field waterfalls, a record-breaking hot spring and a mountain resort village about 130 km north-east of Reykjavik. The drive takes roughly 1 hour 45 minutes each way through the Hvalfjordur tunnel and past Borgarnes, and the trip suits a rental car or a guided tour costing roughly ISK 15,000 to 25,000 per person. The first stop is Deildartunguhver, Europe's highest-flow hot spring, which releases about 180 litres of near-boiling water per second and supplies heating to nearby towns. Boardwalks lead to the steaming vents, and a small greenhouse shop sells tomatoes and cucumbers grown with the geothermal heat. The route continues to Hraunfossar, where clear streams seep from the edge of the Hallmundarhraun lava field into the Hvita river along a stretch of about 900 metres, and to nearby Barnafoss, a narrow cataract with a short path from the main car park. The resort settlement of Husafell offers walking trails, a cafe, the Canyon Baths and access to guided trips into Langjokull glacier's man-made ice tunnel, which should be booked in advance. A typical plan visits Deildartunguhver in the late morning, has lunch in Husafell or a Reykholt cafe, spends the early afternoon at the falls and returns before evening, leaving time for the optional ice tunnel in summer. Reykholt, with the former home of the medieval writer Snorri Sturluson, makes a possible cultural stop on the return. The area is open all year, though paths can be icy and some activities run only from May to September. Summer provides green landscapes and extended daylight, while winter gives a snow-covered setting and northern lights prospects. Food options are concentrated in Husafell and Reykholt, so a snack from Reykjavik is useful.
