Iceland Brown Trout Fishing

Lake Thingvallavatn

Fly Fishing for Wild Browns

Fish Partner—our Orvis-Endorsed Outfitter and winner of the 2025 Orvis-Endorsed International Destination of the Year—guides anglers on Lake Thingvallavatn, Iceland’s largest natural lake at 32 square miles. Fed by nutrient-rich geothermal springs, this vast and fertile water body provides an ideal habitat for some of the world’s largest wild native brown trout, with fish reaching staggering weights of up to 36 pounds.

Located only a 40-minute drive from Reykjavik, Lake Thingvallavatn offers convenient access while delivering an extraordinary trophy-trout experience. Anglers can expect a blend of sight-fishing, streamer casting, and technical presentations to massive browns that cruise the lake’s crystal-clear shallows. The surrounding volcanic landscape and glassy water create a dramatic backdrop for pursuing these legendary fish.

2026 Rates start at $5,750 USD per person for 4 nights / 4 days of guided fishing

Lake Thingvallavatn

Lake Thingvallavatn lies along the North Atlantic Ridge, where the North American and Eurasian tectonic plates separated from each other. Canyons and fissures mark the National Park's landscape and cut the lake bottom in many places, reaching a depth of 377 feet at its deepest point, with an average depth of 111 feet.
The lake's catchment area is 90 percent underground, and the water from thousands of cold springs has a constant temperature of 37 to 39'F. The spring water is filtered through layers of the surrounding lava, making the lake gin clear and large browns averaging 8 pounds easy to spot. Three out of five of Iceland's freshwater fish species live in this lake—brown trout, Arctic char, and the three-spine stickleback.
Season: April 15 - Sept. 15.

Exclusive Beats:

Exclusive Beats: The outfitter has exclusive fishing rights on Lake Thingvallavatn, where anglers can target brown trout weighing up to 36 pounds using streamers. Many 20-pounders are landed during peak fishing from mid-May to mid-June.
At Lake Thingvallavatn, anglers have the option to fish until dark. The best fishing is during twilight—not in complete darkness.
Guided Hours: You're guided up to 12 hours each day. Each beat has a designated season and a limit of two to six rods. All fishing is catch-and-release. At Lake Thingvallavatn, the evenings are generally the best time to catch brown trout, although the daytime can also be rewarding. Each evening after dinner, your guide will pick you up from the Lodge for another round of fishing, and you’ll fish until dark.
Travel Time: The drive to the fishing areas takes 5-30 minutes from the hotel.

The Fishing Program:

Lake Thingvallavatn in Iceland is renowned for its unique species of brown trout that are indigenous to the lake. Thingvallavatn browns can grow to impressive sizes, often surpassing 20 pounds, thanks to the lake's abundant food supply and the absence of significant predators.

Fishing Hours: Fishing hours are flexible, with a 12-hour limit per day.
Guides: Two anglers per knowledgeable, English-speaking guide.
Equipment: No equipment or flies are supplied. A daily rental fee of $110 to $120 per person includes a rod, reel, line, waders, and boots. If you bring your own gear, you'll need to disinfect it before you leave for Iceland, or a fee may apply when you arrive at KEF Airport. All flies must either be new or unused.
Equipment Recommendations: Heavy tackle is recommended. 6 to 9-weight rods and at least 12-pound leaders. Floating lines are most common, but intermediate and sink-tips can also be used. Streamers are effective; dry flies and nymphs work in the right conditions.

Fishing License: A license is included in the package.
Beats: Fish Partner offers access to an unrivaled collection of premium beats around Lake Thingvallavatn, each with its own character and potential for trophy trout and char.

Villingavatnsaros Beat - One of the World's Best

Two Anglers with Bright Browns from Villingavatn

Villingavatnsaros (meaning the mouth of river Villingavatnsa) is one of the greatest brown trout beats in the world. The beat offers the opportunity to catch the giant ice-age brown trout on small nymphs and dry flies. Streamers work great. The beat has a two-rod limit. Some hiking is required.

Villingavatn Beat

Angler with Brown Trout From Villingavatn

Villingavatn: A smaller lake connected directly to Thingvallavatn, offering consistent action throughout the season. Giant browns enter Villingavatn to feed, and fish of extraordinary size can be caught here from opening day through autumn.

The Kaldarhofdi Beat

Kaldarhofdi Beat
Fly and Spin Fishing - the Kaldarhofdi is the only beat in our Iceland packages that includes spin fishing.
May is prime time. This beat is in the southernmost part of Lake Thingvallavatn, where River Sog flows out of the lake. The beat also stretches south into Lake Ulfljotsvatn.
Excellent for Arctic char fishing, especially in June through August. Six to ten rods are permitted on this beat. Some hiking is required.

ION Beats

ION Beat Ölfusvatnsárós: Where the Ölfusvatnsá river flows into Lake Thingvallavatn, creating a powerful confluence that brown trout use as a migration and feeding corridor. In peak times, fish gather here in astonishing numbers.
ION Beat Þorsteinsvík: A secluded geothermal bay where warm spring water bubbles into the lake, creating ideal feeding and resting grounds. Browns and char patrol these warmer pockets aggressively, offering close-quarter encounters in a surreal volcanic landscape.

Mike Sadar's Trip:

"Fishing was slow, but the size was big. Both Chris and I landed six apiece, with mine being at 5, 11, 11, 14, 17, and 21 pounds. Chris had a similar size. We caught these fish in deep holes in the lake using super-long tippets (25 feet). Plan to go back." - Mike Sadar.
