Vallikäär is the green, water-edged parkland beside Pärnu's old fortification line. It is not a dramatic ruin, but it is one of those places that quietly improves a city: a place for walking, concerts, summer events, and a softer approach to the old town.
Together with Tallinn Gate, it helps you read Pärnu as more than a beach resort. The city was once a fortified trading town, and the curves of Vallikäär preserve that older shape in grass and water.
