Is the V3 loop dog-friendly?

While many greenways in France are generally accessible for dogs on a leash, specific regulations for the Brocéliande Forest may apply. It's always best to keep your dog on a leash, especially in wooded areas, to protect wildlife and ensure a pleasant experience for all users.

Do I need any permits or have to pay entrance fees for the Brocéliande Forest?
