Romstjern Lake is integrated into an extensive network of trails suitable for various skill levels. A well-maintained lighted trail runs along its eastern side, providing easy access and a relatively flat path, ideal for beginner hikers and families. For those seeking more challenging routes, trails connect to other notable spots like Stokkevann, Steinbruvann, Lilloseter, and Sinober. The summit of Røverkollen, just 1 km away, offers a moderate climb with rewarding views.

Hikers often combine sections of this trail with other paths in the Slattumsrøa Nature Reserve to create their own loops. The time taken depends on the chosen route and pace, but a leisurely walk along the accessible parts of the lake can take under an hour, while longer excursions into the surrounding forest can extend for several hours.

The area is generally well-suited for hiking and trail running.
Visitors arriving by car can find parking options near Brennaveien, where a forest road leads directly to the lake. Parking spots can fill up quickly, especially on warm summer days or weekends. For public transport, the lake is accessible via the lighted trail from Skytta in the north, and from Steinbruvannet and Grorud in the south, which are typically served by bus routes.
