We start the day with a drive from Reykjavík to Seltún (about 1 hour). The natural geothermal mud pools boiling in the hillside just off Kleifarvatn have pretty strong smell of sulphur and people in the past were of the opinion that this was some sort of a gateway to Hell. The surrounding ground has a light colour which is a strong contrast to the dark lava fields just a little further on and the mud in the pools is mostly a greyish mixture of clay and geothermal water slowly bubbling away.

The largest lake on the Reykjanes peninsula hidden between the mountains not far from the outskirts of Reykjavík known for its natural beauty. Around 8km2 and almost a 100m deep. After a series of earthquakes in 2000 the lake lost almost 20% of its surface and still seems to be losing volume although at a very slow rate. In 2000, as the lake shrunk some curious boxes appeared on the exposed lakebed, their content was later identified as Russian spying equipment dating back to the cold war.

We then travel for about 30 minutes to Gunnuhver. Gunnuhver is a captivating geothermal area nestled on the Reykjanes Peninsula in Iceland. This natural wonder showcases the Earth's raw power with vigorously boiling mud pools and steam vents, creating an otherworldly atmosphere. Visitors can witness the relentless energy beneath the surface, as steam rises dramatically against the Icelandic skyline. Explore the geothermal marvels of Gunnuhver, where nature's forces are on display in a mesmerizing spectacle.

Close by we find the Reykjanes Lighthouse. Perched majestically on the rugged Reykjanes Peninsula, the Reykjanes Lighthouse stands as a timeless guardian of Iceland's coastal beauty. With a stoic charm, this historic landmark overlooks the vast North Atlantic, offering panoramic views of the surrounding seascape. The iconic white structure, adorned with a red roof, is a testament to maritime history and a beacon of safety for seafarers navigating these northern waters. Explore the allure of Reykjanes Lighthouse, where history meets breathtaking vistas in an enchanting dance with the Icelandic winds.

30 minute drive away we stop at the Bridge Between Coninents. You could pick a few spots and say you are right in the middle between the two tectonic plates and given that any of those would still be just a fraction of colossal phenomenon this one is as good as any plus it has a fantastic view. The fissure which the bridge lies across is in the middle of great lava flow with a view of a series of small craters. Out to sea lies Eldey Island, which has one of the largest concentrations of Northern Gannets in the world and was the last known home of the now extinct Great Auk. We continue to Reykjavík after this visit (1.5 hour drive).
