The Dolomites World Heritage Geotrail 31 begins in the charming Casso Village and concludes in Longarone. Parking availability in Casso can be limited, especially during peak season, so it's advisable to check local information or consider public transport options for access to the trailhead.
While dogs are generally permitted on trails in the Dolomites, specific regulations may apply within the Parco Naturale Dolomiti Friulane, which this trail traverses. It's crucial to keep dogs on a leash to protect wildlife and ensure the safety of other hikers. Always carry waste bags and sufficient water for your pet.
The ideal time to hike this trail is typically from late spring (June) to early autumn (September). During these months, the weather is generally more stable, and mountain huts are open.

There are no specific permits required to hike the Dolomites World Heritage Geotrail 31 itself.
