This large Mission Bay playground features a pink roller-coaster-style ropes course and slide that nods to Belmont Park's Giant Dipper next door, plus a separate tot lot and a wide mix of swings including baby, tandem, group and ADA swings. Lifeguarded bay water, fire rings and a beach rinse-off shower round out a full day out.
