Grabrok is a crater formed due to a fissure eruption almost three thousand years ago. The fissure that initially opened during this eruption created Grabrok and two adjacent craters that can be seen from the top. In addition, you can see from above the massive lava field covering about seven square kilometers due to the eruption. Climbing to the top is relatively easy as the crater is only 170 meters (560 ft) high. There is a good path with steps leading to the top. Grabrok Crater is one of the natural attractions near Iceland's ring road and has been popular with Icelanders for decades.

Glanni is a stunning waterfall in the Nordura River. The locals believe it to be the dwelling place for elves and trolls. Glanni is not far away from the Grabrok volcano, the Grabrokarhraun lava field, and the small village of Bifrost. The waterfall is small but beautiful, with at least three side-by-side drops, each with multiple tiers.

Reykholt is one of Iceland's most notable historical sites. It houses a cultural center and a church. Reykholt is most famous for being the home of Iceland's best-known author, Snorri Sturluson, during the years 1206-1241. An ancient geothermally-heated pool, Snorralaug, is named after him. It is one of the few things preserved from Iceland´s medieval period. Snorrastofa is a cultural center and institute for research in medieval studies. Snorrastofa offers historical exhibitions, guided tours, and lectures.

Hraunfossar (meaning "lava waterfall") was a series of streams emerging from the Hallmundarhraun lava field, appearing as a long 900-meter chain of cascades feeding the blue Hvita River. This feature of springs coming out of lava tubes and jagged grooves within the lava made this waterfall unique.

Deildartunguhver is the largest hot spring in Europe and probably the most voluminous natural hot spring in the world. Deildartunguhver is Europe's most powerful hot spring. It provides 180 l/sec of 100°C hot water. Most of the water used for central heating in Borgarnes and Akranes towns is taken from Deildartunguhver.

Krauma Spa (optional entrance fee) was renovated in November 2017, so it is very new and modern. Experience nature from its core by bathing in the geothermal baths at Krauma. The hot water used in Krauma Spa originates in Europe’s most powerful hot spring, Deildartunguhver, at a temperature of 100°C (212°F). To achieve the perfect bathing temperature, we mix the hot water with cold water from Rauðsgil, which originates in the glacier Ok, the most miniature glacier in Iceland. Krauma offers five relaxing natural geothermal baths, a cold tub to get your blood circulation going, two calming saunas, and a relaxation room where you can rest by the fireplace while listening to soothing music.
