Nestled in the middle of the Strømsåsen forest lies this small woodland pond. In summer, Blektjern invites you to take a dip from its wooden bathing dock. Right on the shore you'll find Blektjernstua, a cosy DNT cabin with eight sleeping spots that you can book for a night. If you just need a break, the rest area with a grill is also there for you. Drinking water is available at the outdoor pump all year round.

This is where the Albjerk Ekspressen and Shanty Heisen ski lifts start. It’s a great way to avoid the climb and make the most of your DH biking. There is also a car park here.
