Whale watching was a bit disappointing as we never actually saw any whales and it was not the time of the year for puffins. We did see some dolphins, but it was difficult to take photos. Thoroughly enjoyed Blue Lagoon. Such a stark contrast in temperature, being in your bikini walking to lagoon when it was 2 degrees outside and the lagoon was so warm and relaxing.

Unfortunately we didn't see any whales but we did see dolphins. If you only do one thing in Iceland, make sure it's the Blue Lagoon!!! The tours are very well run and the door to door drop offs are second to none.

Sea was very rough, free seasickness pills were handed out when we boarded the boat and unfortunately we saw no whales at all. We were offered a free return trip to compensate for this, which we didn't take up as we could not have fit it in to the remaining time we had in Iceland. I was seasick despite having taken the pills.
The Blue Lagoon was absolutely fantastic but be aware that the trip does not include the entrance fee to the bathing area. It was expensive, but worth every krona. Especially recommended is the waterfall, just like having a massage and wonderfully de-stressing. I recommend it.
