How to Get There

  • This page covers Northeast Iceland’s Laxárdalur in the Mývatn river system
  • Do not use directions for Dalir or Búðardalur in West Iceland
  • The fishery’s directions approach from Aðaldalur toward Laugar and Staðarbraut, road854
  • For Rauðhólar lodge, get the full directions and access permission from the fishery
  • The operator describes its fishing access as requiring permission and an SUV

Best Time to Visit

  • Summer: Check the Laxárdalur brown-trout permit calendar for the actual fishing date
  • September: Autumn colors in the valley and fewer visitors
  • May: Spring lambing season on surrounding farms, migratory birds returning
  • October-April: Valley accessible but quiet; short daylight makes it a brief stop
  • Book the named Laxárdalur beat rather than a generic Laxá permit

Book the right Laxá stretch

The Laxá in Laxárdalur listing identifies brown trout, flies-only fishing and catch-and-release, with caught fish entered in the logbook. It places the Rauðhólar lodge in this northeastern valley. Similar river names should not be treated as interchangeable permits or destinations.

The listing currently gives a May 31–August 12 season, but elsewhere includes a generic shift note for after August 15. That internal mismatch is a reason to confirm your exact date with the seller. Do not use the old article’s mid-September end date as permission to fish.

Laxardalur FAQs

Quick answers with safety notes where it matters.

What makes the Laxá river special for fishing?

For this valley, look for the specific Laxá in Laxárdalur brown-trout fishery. Do not substitute the separate Laxá in Aðaldalur salmon listing. Confirm the permitted stretch, access arrangements and terms with the seller.

How close is Laxárdalur to Lake Mývatn?

Laxárdalur is directly connected to Lake Mývatn: the Laxá river flows out of the lake and through the valley. The valley begins at the lake's western outlet, so it is one of the most accessible areas in the Mývatn region.

Why is there lava on the valley floor?

The lava covering Laxárdalur's floor originates from volcanic eruptions in the Mývatn area, part of the Krafla volcanic system. Despite the rough lava terrain, the valley slopes are unusually green with grass, moss, and low vegetation, a sharp contrast.

When is the best time to visit Laxárdalur?

June to August is the best time. The vegetation is green in high summer, and the contrast with the dark lava is at its strongest. Fishing dates are specific to the booked beat; check the current permit terms.

What wildlife can I see in Laxárdalur?

The Mývatn-Laxá area is one of Europe's most important habitats for nesting ducks, with 15 species breeding around the lake. The river and valley also support Arctic terns, golden plovers, and the rare harlequin duck. The area is a protected nature reserve.
