Overall we had a great trip. Highlights include: + Hotel Ranga - excellent hotel with a very high-quality restaurant and superb staff. The weather and conditions were against us so we didn't see the northern lights but it was still good to sit in a hot tub and marvel at the night sky. + SouthCoastTours - Northern Lights tour. Really poor weather meant this was a long shot, but we ended up on a black beach, made a camp fire and a unique cocktail by Margaret our guide. + SouthCoastTours - very professional and friendly guides. Our tour of Thorsmork and Waterfalls was very good. Do ask to make sure you see Seljalandsfoss since this is on the way out. We just caught this before losing light but you can also stop by the next day since it's right by the route to Vik. + SouthCoastTours - Ice Caves. Superb guides. The trip itself - I'm sure this is variable depending on the conditions since it's constantly changing. This was the highlight for me - see my favorite picture attached. Amazing ! Note that there's a good Lava Centre that was recommended to us but I think this should be booked ahead of time - but they only run at 13:30 and 17:00 so that didn't work for our schedule. If I could change anything I might have returned to Hotel Ranga after the trip to the ice Caves and enjoyed some quality time there after a few hectic days. Then on the following day, drive the golden circle ending up in Reykjavik. Minor tweak and I'm sure the cost would have gone up - but may have been a practical option. We ended up spending very little time in Reykjavik itself given the touring - next time an extra day to explore and do some of the activities there would be good. Finally, a 09:00 booking at Blue Lagoon worked out perfectly - any later and it gets busy and your schedule squeezed subject to flights. We had time in the lagoon and then into the superb restaurant by 11:45 - highly recommended.
