A very diverse and large park area, which, in addition to hiking trails and viewpoints, also houses proper parks and, at the foot of the peninsula, an old fortress with ongoing military use. Picnic areas and playgrounds, in particular, were also widely used by locals. The infrastructure, including restrooms, etc., is accordingly well-developed, but don't be put off by the fact that there is also heavy car traffic on the roads; we even saw a tourist bus.

The lake's water level depends heavily on the season and the amount of rainfall over the past few days. In summer, the water level is usually low. Nevertheless, it's worth a look, especially since it's located directly next to the parking lot.

It is certainly a very nice walk, although there are certainly parts that require some experience. You can easily break a leg on some parts. Definitely do not start with sneakers on. We are reasonably trained walkers and it took us about 2 1/2 hours. Clambering and climbing experience is useful if you have this.

If you catch a nice day and it is not very busy, the short hike is an impressive experience - volcanism you can touch and smell. We were almost alone there and thought it was fantastic. It shouldn't rain though

We took 1:45 with a 9 year old to hike this trail. The ratings are accurate and half of the trail going up is technical and requires climbing. When raining we would recommend hiking poles. It’s very beautiful and fun.
