The Surna gathers at Øvre Rindal where the Tiåa and the Lomunda meet, and runs some forty-five kilometres broad and steady down the Surnadal to the Surnadalsfjorden at Surnadalsøra, on the border of Trøndelag and Møre og Romsdal. Several smaller rivers feed it from the Trollheimen mountains to the south, and the regulated Folda adds its water through the upper valley. It is a generous, open river — a broad flow over gravel and rock through a wide farmed dale beneath steep fells — long among Norway's renowned salmon and trout rivers, giving up well over a thousand salmon in a good season. The character is classic west-Norwegian holding water: deep pools and even runs on a moderate gradient. Wading is steady on firm gravel and rock, the broad pools rewarding distance and a controlled swing more than any fight with heavy water.
