• Rope-and-net climbing course laid out like an obstacle run, with large climbing cubes around it and soft safety surfacing underneath
• Exercise racks for adults right beside the playground, plus benches, so parents can work out or sit while kids climb
• Beach with a floating pier on Töölönlahti bay, with gear to rent for paddling, rowing or stand-up paddleboarding

The playground sits on the park's activity arch. Its centerpiece is a course-like jungle gym of ropes and nets that gets kids testing their climbing, ringed by large climbing cubes over colorful safety surfacing.

Exercise racks for adults stand beside it, and the city's longest park benches (154 meters in all) line the arch. At the bay, the beach has a floating pier and gear rental for paddling and rowing.
