Holmenkollen is much more than just a ski jump: it’s a symbol of Norwegian sports culture and a popular excursion spot with fantastic views of Oslo. From Frognerseteren subway station, you can start a hike through the surrounding forests. A recommended route takes you over Tryvannshøyden to Tryvannstua, a charming cabin by the lake.

2. Sognsvann – the perfect gateway into hiking heaven
Sognsvann is one of Oslo’s most popular recreational areas — and for good reason. This easily accessible lake offers a flat, 3.3 km loop that’s perfect for walking, jogging, or barrier-free hiking. It also serves as a gateway to Nordmarka, where countless trails lead into the deep forest, past cabins and small lakes. Ideal for spontaneous half-day trips, beginners, or relaxed afternoons in nature.
3. Maridalsvannet – wide views in the Oslo area
Maridalsvannet is the largest drinking water reservoir in Oslo, located north of Grünerløkka. The area is full of rural charm, with old farms, open fields, and forested slopes. You can take a peaceful circular walk here or use the lake as a starting point for further hikes into Nordmarka. The west shore offers particularly beautiful views of the mountains to the north, perfect for photography enthusiasts or a relaxed Sunday outing.
4. Maridalsalpene – spectacular and underrated
The name sounds dramatic, and rightfully so: the “Alps of Maridalen” offer some of the region’s most impressive panoramic hikes. This small hill range west of Maridalsvannet features steep climbs and rocky paths reminiscent of alpine terrain. Those who summit Mellomkollen are rewarded with breathtaking views of the lake and Nordmarka. A great option for experienced hikers seeking solitude and challenge.
5. Nordmarka – Oslo’s green heart
Nordmarka is the largest and most famous forest area around Oslo — a real paradise for outdoor lovers. The extensive trail network allows for endless combinations of hikes, from a few hours to several days. Cabins like Kikutstua, Ullevålseter, or Kobberhaughytta invite you to rest or stay overnight. Lakes like Bjørnsjøen and Skjærsjøen offer swimming or paddling options. Most people start from Frognerseteren or Sognsvann — from there, trails open in every direction.
This traditional cabin in the heart of Nordmarka is a real highlight for hikers, not least because of its legendary waffles. The roughly 5 km hike from Sognsvann takes you through deep forest, along soft forest paths and small streams. Benches and clearings along the way are perfect for breaks. The cabin is open year-round and popular among families, athletes, and nature lovers. From here, you can continue to Skjennungstua or Kikut.
7. Vettakollen – Oslo’s favorite viewpoint
Vettakollen is a true classic among Oslo’s short but rewarding hikes. The ascent from the subway station of the same name takes about 30–45 minutes and leads through dense mixed forest and rocky paths. At the top, you’ll be rewarded with one of the best views of the Oslofjord, the city, and the surrounding forests. The atmosphere is magical at sunset. Tip: bring a picnic blanket — the summit is perfect for lingering.
8. Grefsenkollen – panoramic views with city access
Located in Oslo’s northeast, Grefsenkollen is especially popular with locals. The easy ascent from the Disen neighborhood takes about 45 minutes. At the top, you’re treated to a stunning view of the city and the cozy Grefsenkollen Restaurant, which offers local dishes with a view.

9. Østmarksetra and Mariholtet – a hidden gem in the east
Østmarka is an often overlooked hiking area in eastern Oslo. Starting from the historic Østmarksetra (accessible by subway to Bogerud), a peaceful trail winds through hilly woods and past quiet lakes to the Mariholtet cabin. Along the way, you can stop at places like Ulsrudvannet or Nøklevann — perfect for swimming or picnicking. Mariholtet offers hot meals, coffee, and cake. Ideal for anyone wanting to escape the city’s hustle and bustle.
10. Kolsåstoppen – Oslo meets alpine feeling
Kolsåstoppen, located in Bærum west of Oslo, is one of the region’s most spectacular viewpoints. The trail to the summit involves rocky paths and steep ascents — sure footing is essential. The southern summit especially offers unmatched views of the Oslofjord, Bærumsmarka forest, and on clear days, even as far as Drammen. Depending on the route, the hike takes 2 to 4 hours. Perfect for an active weekend trip with a rewarding payoff.
