We booked a half-day Golden Circle tour with Bustravel (via Iceland4you.is).
When our ride arrived, I was delighted to see it was a small coach - as opposed to a huge one that many other operators use (I much prefer a more personalised, smaller group).
Our tour guide/driver Ingvar, was fantastic. He was friendly, funny and really interesting - providing a nearly non-stop commentary full of interesting facts, folklore and jokes. With the odd fake fact thrown in to check we were still listening. ;) He even managed to make the Icelandic banking revolution both easy to understand and interesting! There was never a dull moment, and he even stopped at one bit of roadside so we could feed some Icelandic horses. (He even provided the rye bread!)
I couldn't recommend this tour, and this guide enough - pick them and you won't regret it!
