Gulen is a cold-water diving hub at the mouth of the Sognefjord on Norway's west coast, pairing more than 25 WWII-era wrecks — led by the 122 m DS Frankenwald — with a shore-diveable house reef holding 73 recorded nudibranch species and an annual March Nudibranch Safari.

Description
Gulen is a small municipality on Norway's west coast at the mouth of the Sognefjord, the country's longest and deepest fjord, about two hours north of Bergen; Gulen Dive Resort at Dalsøyra anchors one of Europe's best-regarded cold-water dive areas. The surrounding sea lanes were a German convoy route in WWII and were repeatedly attacked by Allied aircraft, leaving more than 25 diveable wrecks, headlined by the 122 m freighter DS Frankenwald (sunk 6 January 1940, upright with its deck at 24–34 m and the seabed at 44 m, voted Norway's best wreck by readers of dive magazine Dykking in 2009) and the Ferndale–Parat double wreck at Seglsteinen (sunk December 1944, spanning roughly 6–58 m). The resort's shore-accessible house reef has 73 recorded nudibranch species — reported by the operator as the highest documented count in the Atlantic — and hosts an annual March Nudibranch Safari that has contributed three species new to science, published in 2017. Laminaria kelp forests, a resident wolffish, anglerfish, stingrays on the sand at the 'Stingray City' site, and late-January night encounters with helmet jellyfish round out the marine life. Diving runs year-round in cold water (about 6°C in March to 22°C at the surface in August) with drysuits standard; visibility averages 15–18 m and peaks near 35 m from December to February.
Highlights
What makes this dive worth the trip.
The Gulen house reef has 73 recorded nudibranch species — reported by the operator as the highest documented count anywhere in the Atlantic Ocean — and it is divable from shore directly in front of the resort, with visibility up to 35 m in the December–February window.
An annual Nudibranch Safari runs each March, hosted by specialists including museum curator Bernard Picton, researcher Torkild Bakken, marine biologist Klas Malmberg and underwater photographer Erling Svensen; the next edition is scheduled for 9–14 March 2027.
Gulen's house reef doubles as a citizen-science site: three nudibranch species new to science — Gulenia orjani, Gulenia monicae and Fjordia chriskaugei, published in November 2017 — were found here, and the genus Gulenia takes its name from the area.

DS Frankenwald
Gulen's flagship dive: a 122 m, 5,062 GRT HAPAG steam freighter launched in 1921 at Deutsche Werft in Hamburg, lost on 6 January 1940 when her pilots misjudged the set of the current and she struck Brattholmen in Ytre Steinsund, sinking about ninety minutes later with 7,971 tons of Kiruna magnetite ore. She sits upright on a sheltered bottom at 44 m with the deck sloping from 24 m to 34 m toward the bow and the masts still standing, encrusted in anemones and dead man's fingers. Voted 'Norway's Best Wreck' by Dykking readers in 2009. Since a 2023 collapse of the superstructure, the accommodation, officers' canteen and bridge interiors are no longer accessible.

MS Ferndale & DS Parat (Seglsteinen)
A WWII double wreck on the Seglsteinen rock in Sognesjøen, about 40 minutes by boat north of the resort. The 116 m, 4,302 GRT freighter Ferndale grounded here in mid-December 1944; Allied Mosquito fighter-bombers attacked the stranded ship and the salvage tug Parat the following day and sank them both. Ferndale lies on a steep slope — broken up in the shallows from about 6 m, increasingly ship-shaped below 20 m, with a very intact stern section near 40 m — and from her stern divers can drop directly onto Parat, whose bow sits at about 44 m, bridge at 50 m and stern at about 58 m. Sport divers can work the upper hull; the tug is technical/trimix territory. The current-washed rock itself carries dead man's fingers and dahlia anemones.

Gulen House Reef (Dalsøyra)
The shore reef directly in front of Gulen Dive Resort at Dalsøyra and the most species-dense nudibranch site documented in Norway: 73 species recorded, including three published as new to science in 2017 (Gulenia orjani, Gulenia monicae, Fjordia chriskaugei). Favourable topography, water exchange and nutrients stack several depth levels and habitats — kelp, hydroid and bryozoan turf, sand and rock — into an easy profile down to about 30 m. The resort's resident 'house' wolffish, anglerfish, lobsters, rare gobies and squid share the reef, which is the centrepiece of the annual March Nudibranch Safari and divable around the clock.

Stingray City
The resort's trademark sand-bottom site (position approximate, a short RIB ride from the resort): large stingrays cruise low over the bottom hunting, or lie buried with only their outline showing, and the operator reports sightings on almost every dive here. The supporting cast is unusual — megrim, a deep-water flatfish rarely seen by divers, is regularly spotted at recreational depths, and dragonets are very common, the males showing vivid display colours in early summer. Depths are estimates within the resort's stated 0–40 m site range.

Troll Wall
A drop-off in the Gulen archipelago that starts above the surface and plummets past 45 m, hung with the anemone and invertebrate cover typical of the current-flushed outer coast (position approximate — sites are reached by RIB from the resort). Because the wall spans the whole recreational depth range, it suits everything from guided intermediate dives along the upper section to deeper profiles for experienced cold-water divers.
