Their website says (checked 12 July 2026, not yet operator-confirmed)

“Use fuel stoves for cooking wherever possible, not wood fires. Wood cooking fires are allowed on the condition that they are extinguished with water after use, however they are not permitted on the beach. Cooking fires must be attended at all times. If a wood cooking fire is necessary, always keep it small and where possible light fires where it is already cleared of vegetation, and on the site of a previous fire. Do not collect firewood from the beaches or dunes. Do not cut branches from trees for firewood. Firewood can be purchased from the mainland. Always observe fire bans. Extinguish all fires once cooking is complete. Bonfires are not permitted.”
