Surtshellir is Iceland´s most well-known lavacave, once inhabited by outlaws and sheep rustlers.
It is an enormous lava tube which is easily explored if the right gear is used.
The cave is 1310 m long and 8-10 m high, but at the west end it is only 2-4 m high. Walking in the cave is made more difficult by large rocks that have fallen from the roof. The interior of the cave contains "lavacicles" and ice formations.

A beautifully-formed crater rising 60m above the surrounding lava.
The spatter cone is the largest crater along a short volcanic rift, 200 m in diameter and 50 m deep. Its last eruption was about 5000-6000 years ago. According to medieval chronics there was also one around the time of the colonisation of Iceland about 1000 years ago, but today it is known that it came from another of the many craters of the valley Hnappadalur which are part of the volcanic system Ljosufjoll, the mountains of the light.
It is easiest to approach Eldborg from Snorrastadir on its southern side, walking 2,5 km through the shrub-covered lava field. It is possible to walk all the way around the crater as well as up it.

The meaning of this waterfall translates into "Children's waterfall", but the signs here indicated that there was a saga describing why it got this name. The saga said that there were two children in the Hraunsás household who were supposed to stay home while the parents went to church for Christmas Mass. When the parents returned from mass, they discovered that the children had disappeared (possibly because the children got bored and decided to go out).
They then followed the children's tracks to this waterfall at the stone natural bridge where the tracks disappeared. The mother concluded that the children must have fallen into the river and drowned. Then, the mother had the arch destroyed in order to ensure no one else faces a similar fate. I've seen some accounts say it was by spell or curse, which induced the bridge's collapse by earthquake. In reality, natural bridges usually collapse over time, and given the powerful erosive forces from the rapidly moving river that undercut whatever was supporting the bridge, that could very well have been the fate of the natural arch here.

Deildartunguhver highest flow hot spring in Europe !
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 the towns of Borgarnes and Akranes is taken from Deildartunguhver. The hot water pipeline to Akranes is 64 km long, the longest in Iceland and the water is about 78 - 80 degrees when it reaches Akranes. If you take a shower anywhere within a 65 km radius of the spring, you have already bathed in the hot water from this powerful spring!

The falls was one of those wide river-type waterfalls that we saw quite a few of in the country, but this one segmented into at least three side-by-side drops as well as each one having multiple tiers.

The farmers in the area never made or make hay on the hill, because it is said to belong to the elves living in the area.
Younger lava fields surround this old crater ruin. The higher pillar (75m) was first climbed in 1735 and the lower (61 m) in 1938.

Leading up to it is a fabulous hiking path that should only be attempted by those not daunted by heights or challenging hikes. Glymur is in the river Botnsá that runs out of Hvalvatn, which is a lake closed by molten lava, some 160 metres deep. In Hvalfjordur in West Iceland you can stand in awe before Iceland’s highest waterfall. Standing by the fall you'll have a good view of the surrounding landcape, which is is particularly attractive, as Hvalfjordur is widely considered one of Iceland's most beautiful fjords.The walk, approximately 4 hours roundtrip, will take you from the trailhead at Botnsa river through spectacular scenery including a rock arch and will have you crossing a crystal clear river on a strategically placed log.
