It is not suitable for beginners.

The route is approximately 33.7 km long. While the estimated moving time is around 2 hours and 55 minutes, you should plan for a longer overall duration, typically 4-6 hours, to account for breaks, photo opportunities, and the mandatory 1 km section where you'll need to walk your bike.

There are no specific entrance fees for the park itself, but always check for any updated local regulations or permit requirements for certain activities.

While dogs are generally allowed in the buffer zones and some areas of Aigüestortes i Estany de Sant Maurici National Park, specific regulations apply, especially within the core protected areas.

Dogs are usually required to be on a leash.

The best time to ride this route is typically from late spring (May/June) through early autumn (September/October).
