This small playground is in the Grindelwald village, with great mountain views, particularly of the Eiger.
It's conveniently located right on the main street, near the train station and bus stop, no cable car required. But this also means it's a little noisy with cars driving by, not the same peaceful vibe of an alpine playground.
It's a good place for kids if you are waiting for the train or you are staying in Grindelwald and the kids need to run off extra energy before bedtime.
