By Fly Fishing in Iceland
Nestled in the heart of the Golden Circle, Lake Thingvallavatn isn't just a stunning UNESCO World Heritage site; it's a sanctuary for the angler in search of giant brown trout. With depths exceeding 114 meters and an expansive surface area of nearly 84 square kilometers, this glacial lake is teeming with life and opportunity. The legendary size of its brown trout, often exceeding 10 pounds, will draw any enthusiast who seeks the thrill of the chase.
Fishing here is most fruitful from late spring through early autumn, specifically May to September. As the water warms, expect a diverse range of insect hatches, notably the Mayfly in late May, which often ignites a feeding frenzy among the trout. By June, Caddis Flies take center stage, and I've found that a size 14 Elk Hair Caddis fished during hatch times can yield exceptional results. Evenings are particularly rewarding when the sun sets late, allowing for extended sessions under the midnight sky.
When targeting the majestic Thingvellir trout, employing a strategic approach can make a significant difference. Floating lines can be effective during insect hatches when fish cruise the surface. A long leader (at least 9 feet) will help present your flies delicately in the clear waters. For the more elusive, larger brown trout, I recommend switching to sink-tip lines and using streamers such as a size 6 Woolly Bugger in black or olive, especially in the deeper channels and around structure.
Fishing the northern shores offers prime opportunities as the wind tends to push food towards this side, concentrating fish in the shallows. Casting near submerged rocks and drop-offs is a technique worth mastering, as these areas often harbor the well-fed giants.
Navigating Lake Thingvallavatn's vast waters can be daunting, which is why utilizing the expertise of local guides from Fly Fishing in Iceland is invaluable. Their intimate knowledge of the lake's hotspots, migratory patterns, and the best local flies makes every trip a learning experience. Fully guided day trips from Reykjavik include all the necessary equipment, so you can focus on the fishing rather than logistics.
As a UNESCO World Heritage site, Lake Thingvallavatn is not just famous for its trophy fish but also for its conservation efforts. The catch-and-release ethic is vigorously practiced here. Using barbless hooks and handling fish with wet hands preserves the health of this remarkable fishery. If you're fortunate to land a trophy brown trout, consider a quick photo before releasing it to continue its aquatic journey.
