It's a very fortunate thing that people's fascination with nature never ceases, and while some people travel the world to go bird-watching, on safari, or whale-watching, some have even more specialised interests like salmon. About three hours drive northeast of Stavanger in Norway you can suit up and plunge into the Suldalslagen river - This is not about fishing but all about observing, and by the end of the day a proper sighting is like icing on the cake.
