Trollheimen Triangle Hiking Guide: Trails, Huts, and Logistics

The Trollheimen Triangle is a premier multi-day hiking route located in the Trollheimen Mountains of central Norway. Spanning approximately 58 kilometers (36 miles), this loop trail connects three historic mountain huts and traverses a diverse landscape of ancient woodlands, jagged rocky peaks, and crystal-clear mountain lakes. Known as the "home of the trolls," the region is celebrated for its unique transition zone between marine and alpine environments.

Trail Overview

The route is typically completed in 2 to 3 days and is rated at a moderate difficulty level. It features a total elevation gain of 2,720 meters (8,924 feet). The trail is managed by the Norwegian Trekking Association (DNT), and while it is well-known within the Norwegian outdoor community, it remains a relatively quiet destination for international travelers.

Planning and Logistics

Getting There

The regional hub for the Trollheimen Triangle is the town of Oppdal. During the summer season, a periodic bus service connects Oppdal to the Gjevilvasshytta Hut, which is located 23 km (14.3 mi) away. For those utilizing private transport, parking is available at the trailhead and an alternate lot situated 1.5 km northwest of the hut.

Seasonal Availability

The primary hiking season runs from mid-June to late September. Outside of this window, weather conditions can be severe, and the mountain huts may be closed or unstaffed. No permits or fees are required to hike the trail itself.

Water and Supplies

• Water: H2O is abundant along the trail. While many hikers choose to filter their water, fast-flowing streams in the region are generally considered safe for consumption.
• Food: Hikers can carry their own provisions or purchase meals at the full-service huts. If hiking late in the season (e.g., late September), travelers must be self-sufficient as hut services may be unavailable.
• Navigation: Digital maps such as GaiaGPS and AllTrails are recommended. The DNT website provides basic trail descriptions and booking portals for accommodation.

Route Stages

The Trollheimen Triangle is traditionally hiked in a counter-clockwise direction, starting and ending at the Gjevilvasshytta Hut.

Stage 1: Gjevilvasshytta to Jøldalshytta

• Distance: 21 km (13 mi)
• Time: 5–7 hours

The first stage begins at Gjevilvasshytta (established 1819) and ascends through the birch forests of the Gjørdøldalen Valley. After approximately 5 km, the trail emerges above the treeline. Hikers cross a wide saddle beneath Høghøa Peak (1,308 m) before descending into the marshy Høghødalen Valley. After crossing the Minnilla River via a footbridge, the path continues over the rolling fells of Skrikhøa Peak (1,061 m) and descends into Gammelsæterdalen Valley toward the Jøldalshytta Hut, which overlooks Jølvatnet Lake.

Stage 2: Jøldalshytta to Trollheimshytta

• Distance: 16 km (9.9 mi) for the valley route; varies for high traverses.

This stage offers three distinct paths depending on weather conditions:

1. Geithøtta Top: A high traverse reaching 1,316 m.
2. Trollhetta: A more challenging high traverse reaching 1,616 m.
3. Svartådalen Valley: A low-level route following the Svartåa River. This route is preferred during inclement weather and features storybook bridges, luxuriant meadows, and turf-roofed cottages.

The destination, Trollheimshytta Hut, is situated in the heart of the mountains. A day/emergency shelter is available even when the main hut is closed.

Stage 3: Trollheimshytta to Gjevilvasshytta

• Distance: 21 km (13 mi)
• Difficulty: High (Toughest stage)

The final leg begins with a steep climb, gaining 700 meters of elevation over just 3 kilometers. After reaching Skallen Peak (1,226 m), hikers are treated to views of the Svartåmoen Nature Reserve. The trail then crosses the Mellomfjellet Plateau, a rocky area filled with tarns. After passing Fossådalsvatnet Lake, the trail climbs to the highest point of the stage, Riarskaret Pass (1,307 m). The descent leads through the Gjørdøldalen Valley, parallels the Gravbekke river, and offers expansive views of Gjevillvatnet Lake before returning to the trailhead.

Accommodation and Camping

• Mountain Huts: There are three full-service huts: Gjevilvasshytta, Trollheimshytta, and Jøldalshytta. During the peak months of July and August, it is essential to book spaces in advance.
• Wild Camping: In accordance with Norwegian law, wild camping is permitted throughout the Trollheimen Triangle.

Cultural and Historical Sites

The region has a rich human history dating back to the Stone Age. A recommended excursion near the trailhead is the Vang Burial Site (Gravfeltet Vang) on the outskirts of Oppdal. This is the largest Iron Age burial site in Norway, featuring over 900 burial mounds primarily from the Viking Age (750–1050 A.D.). Artifacts found at the site, such as swords and jewelry, indicate trade connections reaching as far as the British Isles and southern Europe.
