How to fish it · for Atlantic Salmon
When
Late June through mid-September. The Laxá í Kjós is a classic short Icelandic salmon river — fish through the day in cool weather, harder in bright sun.
Where
Named pools through the Kjós valley above the sea. The river is intimate — short casts, careful approach. Heads and tails of every named pool.
Method
Hitch tube on a floater is the Icelandic signature — small cone-head sizes 12 to 14, hitched across-and-down. Conventional small wets and tubes when the hitch isn't on. Single barbless mandatory; mandatory C&R on most beats.
Kit
11 ft switch or 10 ft #7/8 single-hander — most Icelandic beats reward short-rod accuracy. Floating line. 10 to 12 lb fluoro tippet.
Why this works
Very poor — water clarity is working for you, but water temperature is the limiting factor today.

Laxá í Kjós is the practical south-west option — about an hour from Reykjavík — combining a first-class salmon river with a strong July run of large sea trout. There is no national licence; access is a lodge-package rod allocation rotating through the beats, sold as multi-day rods rather than walk-up day tickets, though day rods are more often available here than on the ultra-exclusive northern rivers. Salmon and sea trout fish as separate lanes; the Meadows sea-trout section is normally outside the ordinary rotation. Confirm the current rod count, rotation and how the Meadows is accessed before relying on this.

Lower salmon waterBallot
Current fishery manager (verify)
The lower pools and fall-and-pool sequence down to the tide — the main salmon entry, fished within the rod allocation. Compact, intimate water rewarding short casts and careful approach.
Upper salmon waterBallot
Current fishery manager (verify)
The upper salmon/grilse pools, including the steep canyon water around Laxfoss and Þórufoss — fished within the same rod allocation. Care needed on smooth ledges around the falls.
The Meadows — sea-trout sectionBallot
The Meadows is the sea-trout specialist water, normally outside the ordinary beat rotation, separating the upper and lower river and holding large sea trout (5–7 lb) from mid-July through August.
