The light isn't bothering us. Kevin managed to sleep till 9 and Joan an hour later till 10 am.

We were returning to Myvatn but as it is over an hour's drive and there was still a lot to see and do, we decided to do some shopping first. In Akureyri there is only one place you can buy alcohol "off licence" and it's just around the corner from where we are staying. Yes, wine is about 50% more than at home but local lager is reasonably priced. Speckled Hen though was £3.70 for a 350 ml bottle!!

We then headed to Icelandic supermarket chain Bonus. The traffic lights in Akureyri have a heart shaped "red" - seemingly a gesture to cheer things up at the time of the 2008 Icelandic banking crash. It made us smile! Again provisions in the supermarket were about 50% more and not a wide range but it is an town of 18,000 - about 50% bigger than Bolsover.

Today we headed back past Reykjahild on to volcano Krafla. On the way up, we had lunch by a warm stream beneath the geothermal power station. The stream's bed was blue and yellow with the familar sulphur smell. You can drive right up to the rim of the Viti crater which has a blue lake inside and spectacular views all around. It is surrounded by the sandy orange signs of geothermal fields. Next a short drive to see Leirhnjuker - a walk over lava fields to see the cravasses where Krafla was last active in the 1970s-80s. Along a hillside there were more bubbling pools and hissing smoke. Though Krafla has a summit, the whole volcano is spread over a large area.

Next it was a trip to the Myvatn nature bath. Created in the 2000s, and possibly the most expensive hot spa we have been to at £30 entry. Inside was busy but never too crowded, with two large pools overlooking the lake. Whilst we were there the air temperature dropped from 18 Celcius to 13 - distinctly chilly.

The sun was getting lower so we drove down the east side of the lake. First was Grjotagja, a fissure with a hot pool in it accessed by a small scrabble. Seemingly it played host to a a rather steamy scene in Game of Thrones. Nearby was the looming black cone of Hverfell but time was running short so we didn't climb it. Passed the strange lava pilars at Dimmuborgir our final stop was the pseudo craters at Skutustadagigar, seemingly a very rare phenomenon, that look like volcanos but are made by water pushing throug lava.

The drive back was interesting - a combination of low sun in the west and a fly splattered windscreen. A late dinner and bed just before 1 am - and it wasn't even properly dark. Photos are separate under Krafla.
