We went to Seljalandfoss before taking a ferry to Heimaey in the Westman Islands/Vestmannaeyjar in the morning. We got there before tour buses from Reykjavik started to arrive, which was a plus because we had the falls all to ourselves. The minus was we couldn't spend a lot of time there because we had a ferry to catch. I also didn't want my clothes to be all wet and my boots all muddy on the ferry ride so I didn't do the walk behind the falls. My husband did, though. But then again, he's always been more adventurous than me. Seljalandfoss is lovely and all but it's not really one of my favourites in Iceland.
I was unable to take pictures of so many Icelandic attractions in all their glory due to the lack of wide-angle lens (the widest I could get with my micro 4/3 camera was around 40mm) and it was quite frustrating for me at times. For those going to Iceland, if you own a wide-angle lens, don't forget to pack it. If you don't own one, buy or borrow one from someone! You won't regret it. The next time we go there, I am so taking my DSLR with an ultra-wide angle lens. Sure it would be heavier to carry but it's not like we'll have to go on a long hike or anything. Most Iceland attractions are located right by the side of the road! Just one of the reasons I love Iceland, being a wimpy hiker and all. :-)
