    UTVV Long Distance Trail is a 160 km permanent loop encircling the Vipava Valley with 6,000 meters of cumulative ascent. Designed on the backbone of the UTVV race terrain (Emperor route), it connects exposed ridgelines, karst plateaus, forest of Trnovski gozd, and the iconic limestone edge above the valley.

    The route follows existing mountain trails and remote paths, combining technical rocky sections, runnable forest tracks, and panoramic traverses shaped by the strong local wind – the Burja. It is intended for experienced hikers, trail runners, and fastpackers who are comfortable with long distances and self-sufficiency.

    The trail can be completed in multiple stages or as a multi-day endurance challenge. Villages along the valley provide access points, water, and accommodation options, allowing flexible planning.

    This is not a race course but a permanent outdoor experience – a full-circle journey around one of Slovenia’s most diverse landscapes.

    Author’s recommendation

    Plan stages carefully, carry enough water on remote sections, and respect the Burja wind on ridgelines and weather conditions.

    Safety information

    This is a demanding long-distance mountain trail with significant elevation gain and remote sections.

    The weather can change rapidly, especially on Nanos, Čaven, and Trnovski gozd.

    Strong Burja wind may affect balance and visibility on exposed ridges.

    Some sections are rocky and technically demanding.

    Water sources are limited on karst terrain — plan accordingly.

    Snow and ice are possible in winter and early spring.

    Mobile signal is not guaranteed everywhere.

    Hikers are responsible for their own safety.

    Tips and suggestions

    Best seasons: April–June and September–November.

    Start early during summer due to heat exposure.

    Consider dividing the route into 4–6 stages.

    Support local huts, farms, and guesthouses along the valley.

    Always check the weather forecast before committing to the trails.
