Lake Thingvallavatn, a majestic expanse nestled within Thingvellir National Park, offers some of the most exhilarating brown trout fishing in Iceland. With depths reaching 114 meters and a unique ecosystem, this UNESCO World Heritage site is a prime destination for anglers seeking giant brown trout that can exceed 10 lbs.

Seasonal Patterns and Strategies

Timing is everything when targeting the Thingvellir trout. The prime fishing season runs from May to September, with the late spring and early summer months yielding exceptional results. During this time, the water temperature hovers around 10-15°C, triggering prolific insect hatches and fierce trout activity. Hatches are abundant, particularly with midges and mayflies. Pay attention to the size 16 Griffith's Gnat and size 14 Pheasant Tail Nymph, particularly in the early mornings and late evenings. Casting these flies near the shallow shores or around submerged structures can result in aggressive takes.

Fly Fishing Techniques

When engaging in Thingvallavatn fly fishing, the strip retrieve often proves effective. Strip the fly through current seams at varying speeds to entice the fish. The floating line with a long leader (12-15 feet) helps present your flies delicately, especially when targeting the feeding trout that are often skittish in clear waters.

Using sinking tip lines can also be advantageous when fishing deeper waters. The size 6 Woolly Bugger fished near drop-offs can provoke strikes from larger brown trout lurking below. Anglers should be prepared to adapt techniques based on water conditions and fish behavior observed throughout the day.

Gear Recommendations

While Fly Fishing in Iceland provides top-notch equipment for all trips, having your personal gear can enhance your experience. A 9-foot, 5-weight rod is a solid choice for this type of fishing, paired with a reel capable of holding a weight-forward floating line, and a spare spool with a sinking line for varying depths.
