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
Good — river flow is working for you, but time of day 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.

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

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.
Permits & access
Permit required — see local rules.
  • River-specific booking and catch rules apply, and this accessible salmon river can still require advance planning in the better periods
  • Check current salmon and sea-trout regulations before fishing.

About this water

Close to Reykjavík, a productive salmon river that also has a strong sea-trout dimension. Compact, accessible water with easy wading and practical value for visiting anglers who want a realistic south-west Iceland salmon-and-sea-trout option rather than an ultra-exclusive river. Volcanic bedrock underlies this river. Iceland's salmon are managed conservatively under operator and national rules — quotas, size limits and catch-and-release are widely applied; check the river's rules before fishing.

Under the surface

Laxá í Kjós drains Lake Stíflisdalsvatn and falls some seventeen kilometres through one of southern Iceland's most strikingly glaciated valleys to Laxárvogur on Hvalfjörður, less than an hour from Reykjavík. The river reads the valley's three moods in turn: a tumbling, steep-sided canyon at the top, where it cascades over the rocky steps of the Laxfoss and Þórufoss; a gentle, arable floodplain in the middle, where it meanders quietly over gravel; and a final fall-and-pool sequence down to the tide. Its delicate tributary the Bugða — where Iceland's first salmon hatchery drew its brood stock in 1884 — winds clear and small through the flats, paradise for light dries and nymphs when the main river sleeps. The substrate is volcanic gravel and rock; wading is mostly kind, with care on the smooth ledges around the falls.
