A revised edition with a new area included. This book describes enough rivers to keep you happy for several holidays in the Austrian and Swiss alps. Having paddled the majority of the rivers featured I can testify to the accuracy of the orinal although this edition does seem to be more plagued with typos, just hope they don't extend to the descriptions. Other guides may include more rivers but if you're looking for an english language guide for the major rivers of the area in a clear format you shouldn't leave home without it, unless you have the first edition to hand.
Descriptions of the smaller runs in the Lech valley have been removed, a shame as the Hornbach was memorable to say the least.
