Traveling in Iceland using this new edition of the Rough Guide gave me and my wife the impression that the author did not like Iceland. Simply put, there was ample evidence that most of what was written was obtained by an online search or word-of-mouth. There were a number of inaccuracies and omissions that would be unimaginable if the author had actually spent time in Iceland. In all likelihood, it was written from a three-day stay in Reykjavik during July (the height of tourist season). Here are some examples of the lazy writing that caused us MANY headaches:
-It is assumed that everyone in Iceland (locals and tourists) has a cellphone. There are rarely any phones available in hotel rooms or B&B's, and many times the phone number listed for a B&B is the cellphone of the owner. This was not mentioned in the book.
-Some towns are simply not mentioned. While the towns in Iceland tend to be very small and would not rate a mention in most guidebooks, this is true of 90% of the towns. There are only 320,000 people in Iceland - their towns can all be listed. For example, try finding Suðureyri in the guidebook. Not there. The town is a fairly substantial fishing village near Ísafjörður.
-Puffins: it is no secret that Iceland is home to many nesting grounds for puffins. We traveled to Iceland in the second half of August expecting to find puffins. According to the guidebook, the puffins can be found from April to Mid-September. Good luck with that. Any local can tell you (and will, if you ask them) that the puffins all leave by Mid-August. After August 15, you can only expect a few isolated puffins anywhere around Iceland. You might get lucky and find a group stopped at a southerly stop for a while (we did), but don't count on it. Where we saw a flock of puffins (at Vestmannaeyjar), none had been spotted a week prior. Yet another example of lazy, inaccurate writing that could have been corrected by some cursory research.
-Opening hours: we found more than one attraction with incorrect hours listed. Don't trust any times that say open after 18:00.
-Laugavegur: Everything written about the laugavegur lists it as a four-day hike from Landmannalaugar to Þórsmörk, with no other options. The author clearly pulled all of his information about this trek from other sources and did not try it himself nor talk to someone who had. While it is a full four days from start to end, there are buses that can be hired that reach Álftavatn (and Emstrur), which cut the walk in half - something useful if you wish to go elsewhere. Taking a bus either in or out of Álftavatn also avoids all of the potentially treacherous river fordings. The hike from Landmannalaugar to Álftavatn is also, by far, the most scenic portion of the hike.
-Buses: The only bus routes mentioned in the book start and end in Reykjavik. While those routes certainly exist and are useful, there are many other routes that start and end elsewhere. Bus tickets start at ~$50 a ride/person. Knowing all of the possibilities will help with planning more interesting excursions into the interior of Iceland without losing days on a bus.
-Roads: the road conditions and experience of driving in Iceland is quite different from the U.K. (including Skye) or mainland Europe. Doable, but be ready for very rough terrain (even the "good" roads). Not mentioned in this book.
I leave these bits of advice as examples of why you should find a different guidebook and as helpful tips to those wishing to go to Iceland (which is GREAT!). Good luck!
