Thingvallavatn – Þorsteinsvík (ION beat)

Þorsteinsvík is one of the most sought-after fishing areas on Lake Þingvallavatn and part of the legendary ION beats. Now exclusively available to Fish Partner guests, this bay offers some of the best chances in Iceland to connect with truly giant brown trout.

The Fishing

What sets Þorsteinsvík apart is the geothermal spring water that flows into the bay. The warmer water creates a unique micro-habitat where both Arctic char and brown trout gather in large numbers. For the browns, this warm inflow provides the perfect environment to rest and digest food more quickly, allowing them to grow to extraordinary sizes.

Anglers can expect to encounter powerful wild browns regularly in the 5 lb range, with even bigger fish caught regularly.

Fishing is fly-only and strictly catch-and-release, ensuring that this remarkable fishery remains protected for generations to come.

Þorsteinsvík combines stunning natural features with an extraordinary concentration of fish, making it one of the most productive and exciting areas on Lake Þingvallavatn.

NOTE:
On Saturdays & Sundays, only half the bay is open to fishing. Marked on photo below is area that is not allowed to fish on weekends.
