These are just brilliant- great people doing fantastic things. Many people find their daily free walking tour around Reykjavik a great way to find their way round the city. You will find them by the old harbour - look for the turf roof and totem pole next to Elding Whale Watching offices.
However the real treasures are the day tours out of Reykjavik. I have just returned from their Glacial Lagoon Day trip, and it was so much more than anyone could anticipate. I am still amazed at what I saw and did in one day
They go that extra mile and don't work to a strict timetable, but adapt to the wishes of the (small) group and the weather. On our day we not only saw (and took a boat trip) on the Glacial Lagoon where we saw seals, but were also taken to another hidden one, walked on a glacier, walked on black beaches, rolled on springy moss in a lava field, stood behind a waterfall in the midnight sun, bathed in a geothermal pool at the base of Eyjafjallajökull, and so much more, all the time being given a real insight into Icelandic nature, culture and history.
These are small group trips (there were only four of us along with our guide) with interesting people and so far removed from the scripted tightly timed tours one normally experiences, it really was like a day out with friends. And what a day - probably one of the most memorable of my life.
Don't let the published prices put you off. We were out for 19 hours and saw and did so much that it makes it excellent value - much better than the usual bus tours (and anyway one can't put a price on what one experiences with them). If you ever go to Iceland, well worth looking up- I can't wait to return!
Interesting day trip from Reykjavik, although I went for a long weekend just for the diving. You get to scuba dive along the volcanic cracks where the European and North American plates meet. Utterly fantastic visibility of 100m or so underwater. You get guided through and can hire all equipment. The more experience you have beforehand the better to enjoy it rather than fight a hired drysuit for the first time. If you show you know enough they may take you to the lower levels, which are up to 40m deep and totally enclosed - great fun, but not for everybody. Go in wintertime as it is quietest then.
Many activities in Iceland can only be done via coach trip from Reykjavik; if you go to the places where they occur you won't always be able to do them; the only exceptions are the popular places and/or popular things like horse riding.
Go to Tourist Information; there are several official/unofficial ones in "downtown" Reykjavik.
