• Fountain off in winter: the lake fountain runs every 15 minutes the rest of the year
• Bring your own fuel for the six public grill spots, which can't be reserved; portable grills aren't allowed
• Toilets in the restaurant: use the ones in the Seegarten, a few minutes' walk from the minigolf and carousel

Built for the Grün 80 garden show, Park im Grünen spreads across lawns the size of about 18 soccer fields. The St. Alban-Teich and its fountain sit at the center, near a 45-meter dinosaur model and a Bernhard Luginbühl iron sculpture that doubles as a play structure.

Kids also get a playground, an 18-hole minigolf course, a vintage carousel, a Kneipp foot bath and six public barbecue spots.
