🌱💧A beautiful wetland area surrounding various ponds. Caution: Even in spring, there may still be snow there, as it's much colder in the hollows. Plank paths lead through some of the area, but they can be difficult to find in the snow. So, it's easy to break through the snow and plunge straight into the cool water. 🥶
