I'd be happy to help you with your question! However, I must clarify that I don't have access to the specific rules and regulations of Campingplatz Ruhrtalblick in Essen, Germany regarding open fires. It's important to note that fire safety regulations can vary from one campsite to another, so it's always a good idea to check with the campsite directly for the most up-to-date information. That being said, I can provide you with some general guidelines about open fires at campsites in Germany based on my research: 1. Open fires are generally not allowed at campsites due to fire safety concerns. Instead, campsites may provide designated fire pits or barbecue areas for guests to use. 2. If open fires are permitted, they must be supervised at all times and kept a safe distance from tents, trailers, and other structures. 3. Only dry wood can be used for open fires, and no green or wet wood should be burned. 4. Open fires must not be left unattended and must be completely extinguished before leaving the campsite. 5. Fireworks are generally prohibited at campsites in Germany. I would encourage you to contact Campingplatz Ruhrtalblick directly for the most accurate and up-to-date information about their specific fire safety regulations. Their website or customer service department should be able to provide you with the information you need. I hope this helps! Let me know if you have any further questions.
