If you're like me and like to do "gravel up, singletrail down" this cabin with its cafeteria is perfectly located as several of the best trails in the area (like E6, Bunghole, Hobo...) start just south of this place. After you have exhausted yourself climbing the gravel up here, treat yourself to a coffee or waffle (or both) before you start the fun part of your trip down to Sognsvann again. You deserve it!

The Katnosa area is rich in natural beauty. You'll find Katnosa lake itself, which is a regulated lake, and the Katnoselva river, part of a network of waterways. The Spålen–Katnosa Nature Reserve protects extensive spruce forests and wetlands. A historical point of interest is the 1886 Katnosdammen dam, which regulates the lake. There's also a self-service cabin at Katnosdammen offering views of the lake.
The best time for mountain biking in Katnosa is generally during the warmer months, from late spring through early autumn, when trails are clear of snow and ice. During this period, the forested hills and lake areas are most accessible and enjoyable. Always check local weather conditions before heading out.
While the immediate Katnosa area within the nature reserve is quite wild, the self-service cabin at Katnosdammen can serve as a resting point. For more established cafes or pubs, you would typically need to venture closer to the more populated areas bordering Nordmarka, such as those accessible from Sørkedalen or Myllsdammen, which are common starting points for routes into the region.
When mountain biking in Norway, it's important to be considerate of other trail users, including pedestrians and skiers. Always limit your speed, stay on designated trails, and avoid riding on vulnerable or soft terrain, especially in protected areas like the Spålen–Katnosa Nature Reserve. Respecting nature and other users ensures a pleasant experience for everyone.

Access to the Spålen–Katnosa Nature Reserve, where many of the mountain bike trails are located, can be challenging directly by public transport due to its remote nature.

Planning your journey in advance and considering a combination of transport methods is advisable.
Generally, there are no specific permits required for mountain biking on established trails within the Spålen–Katnosa Nature Reserve. However, as it is a protected area, it's crucial to adhere to general trail etiquette, stay on marked paths, and respect any local regulations or signage regarding access and environmental protection.
