Hetta-Pallas
Finland's most popular long-distance trail, first marked out in 1934 in Pallas-Yllästunturi National Park. It crosses fell after fell, dropping into ravines between them as if to prepare you for the next breathtaking view from the summit ahead.
Getting to the trailhead
From Helsinki, fly to Kittilä or Rovaniemi, or take the overnight train to Rovaniemi, then rent a car for the drive to Hetta.
Start at Tunturi-Lapin luontokeskus, Peuratie 15, 99400 Enontekiö. A local boat operator crosses Lake Ounasjärvi to the trail start (roughly June to October, paid), or you can walk around the shore.
At the Pallas end, a car-relocation service can move your vehicle from Hetta to the Pallastunturi car park while you walk.
Plan by season
Temperature
10–20 °C
Daylight
24h midnight sun (to early Jul)
Trail condition
Best after midsummer, dry and firm
What to pack
The easiest season, but Lapland weather swings fast and the open fell sections offer no shelter from sudden rain.
Wicking base layer plus a light fleece for cool evenings (down to 5 °C)
Waterproof, windproof shell — rain arrives suddenly on the open fells
Sturdy waterproof boots for wet mires and stream crossings
3-season sleeping bag and pad; huts can fill up
Mosquito repellent and a head net — July can be intense near wetlands
Lightweight stove plus a water filter or tablets as backup
Elevation profile — tap a stop
Hetta
Tunturi-Lapin luontokeskus, Peuratie 15, 99400 Enontekiö. Cross Lake Ounasjärvi by boat with the local operator, or walk around the shore to reach the trail start.
Good to know
Water
Marked water points at every hut and campfire site. Stream water is generally safe but boil it in warm weather, especially near reindeer grazing areas.
Camping
Allowed only right next to huts, kotas and lean-tos along most of the route. Tents are unrestricted only in the designated wilderness zone.
Campfires & toilets
Several campfire sites along the way — check the current wildfire warning before lighting one. Composting toilets at camp sites; bring your own toilet paper.
Waste
No bins anywhere on the trail. Bring a rubbish bag and carry everything out with you.
Mobile signal
Patchy mobile signal on fell tops, often none in valleys along the middle stretch.
Trail markings
Well waymarked and easy to follow the whole way — Finland's oldest marked long-distance trail (since 1934) and its most popular, so the route is clear and well-trodden.
Emergency & winter
112 works across the EU even with low signal. The trail is only walkable on bare ground — in winter, stick to the lower ski routes instead.
Segment by segment
Hetta to Pyhäkero
6.7 kmThe route starts in Hetta, the main village of Enontekiö, with a crossing of Lake Ounasjärvi or via the Mustavaara estate road. Local operators run the boat crossings. The path runs through pine heath forest all the way to the Pyhäkero wilderness hut.
Pyhäkero to Sioskuru
8 kmA long climb from the Pyhäkero hut to the fell top starts gently, steepening near the summit. Remnants of early ski-tourism days can be seen by Lake Pyhäjärvi, once home to one of the area's first tourist lodges. From the summit, sweeping views open toward the great fells of Käsivarsi and south to the Pallas fells, and on clear days northwest to the snow-streaked peaks of Pältsä and Moskukainen on the Norwegian and Swedish border. The route then descends across damp slope mires and gravel ridges to the Sioskuru hut.
Sioskuru to Pahakuru
12.1 kmFrom Sioskuru the route climbs to Sios- and Sillavaara. To the west lie Haaravaara and Välivaara, backed by the massive Rautuvaara. The path gradually descends and crosses the river Marastojoki. The Tappuri wilderness hut and the Marasto reindeer round-up site are passed on the left. The route continues to Rouvivaara, opening onto a broad fell plateau with views to the Pallas fells, then crosses easy upland terrain to the Pahakuru hut.
Pahakuru to Hannukuru
1.5 kmFrom Pahakuru the route continues to the Hannukuru huts. The Ounastunturi fells fall behind as the Pallastunturi fells open up ahead. The path crosses an old reindeer round-up field, where dense juniper bushes surround a flat clearing and old, wind-bent mountain birches line the way, before reaching level heath and the huts.
Hannukuru to Montellin kota
12.5 kmFrom Hannukuru the route descends fairly steeply over the river Hannujoki, which runs between steep, rocky slopes, then continues toward Suastunturi. Though gentle and flat-topped, it still offers fine views — wetland meadows once mown for cattle fodder lie to the west, with Ruototunturi in the park's wilderness zone. The path runs through dense spruce and birch forest to the Suaskuru kota. More climbing follows toward Lumikero, from whose summit the winding Ounasjoki can be traced for miles. The path descends into Lumikuru, where a reindeer fence between the Näkkälä and Kyrö herding districts has a crossing bridge, then skirts the west side of Vuontiskero and descends to Röyninkuru and the kota beside the old Montelli reindeer cabin.
Montellin kota to Nammalakuru
1.2 kmThe route to Nammalakuru continues south. After a small climb it descends to the Nammalakuru hut. A side route also branches east from Montellin kota toward Vuontisjärvi.
Nammalakuru to Pallastunturi
13 kmFrom the Nammalakuru hut the route winds along the birch and spruce treeline toward the edges of Jäkäläkero and on to the Rihmakuru kota (3 km from Nammalakuru). From there a long climb through the Rihmakuru hills leads toward the Taivaskero saddle. East of Taivaskero (807 m), the highest point on the ridge, lies the deep, dramatic horseshoe-shaped Pyhäkuru ravine, whose steep walls drive powerful updrafts straight into the sky. Ahead on the horizon stands Ylläs, with Jerisjärvi closer by and Sammaltunturi and Lommoltunturi within the national park. The route descends south of Pyhäkero into Vatikuru and on to Pallastunturi.
