Trail Reviews
We're back on holiday for a few days, just the two of us and the dogs. This time in Belgium, near the charming town of Spa. We arrived yesterday evening, and today we started the day with a leisurely breakfast... and then our legs were already itching to get going. The Coo waterfalls were high on our list, but we deliberately saved them for last; after all, dessert tastes best after the main course. The first part of the route led us along the large lake of Coo, immediately starting with a steep climb that gave our calves a workout. Soon we saw the highlight "challenging rope path" appear on the map. We looked at each other: What are we getting ourselves into now? Well... an adventure! Steep, strewn with rocks and tree roots, and indeed: a kind of rope banister from which we gratefully hung as if our lives depended on it (okay, a bit dramatically). Halfway through, we were rewarded with a view of Plopsaland Coo. It feels strange, such an amusement park suddenly surrounded by greenery. After that, we walked past Coo's impressive hydraulic power station. A technical marvel that not only generates energy but also offers a magnificent view of the lake. In the background, the Ardennes hills and endless forests towered above everything. Belgium at its finest. Just before the end of the route, we were given an unexpected challenge: obstacle courses over felled trees. A crane operator was loading large logs, looked at us, and kindly gestured for us to pass. Well... allowed is one thing, could is another. But we clambered past as if we were auditioning for Expedition Robinson. Joep immediately took off like a seasoned mountain goat, high over the logs. Bailey watched and thought: "I can do that too." Fortunately, that proved to be true, and a minute later we were back on the path, proud and unharmed. And then: the dessert of the day. Near the parking lot, a small staircase descended. With each step, the view became even more spectacular. Until we stood there, completely alone, watching the thundering torrent of the Coo waterfalls. What a force of nature! We suspect this is different in peak season, probably a queue on the steps, but today we had the place to ourselves. A beautiful end to a wonderful day in the Ardennes.
📍 Coo Waterfalls and surrounding area. 🇧🇪 Last night we decided to go to the Coo Waterfalls today. 🌊 We'd seen a walk there a while ago, and we really wanted to try it. 🥾 This morning we left for Coo later than planned. Luckily, it was only an 11-minute drive. 🚗 Once there, we started the walk and quickly noticed what a beautiful area it is. 🤩 We strolled around the water and finally took a quick look at the waterfalls. 👍 Nice to see once, but personally, we expected more. 😉 That doesn't change the fact that the walk was very enjoyable. We had a great time again. 😍
