Wander down any of the roads to the right and you’ll reach Tivoliparken, known locally as the “English Park”, with avenues of horse-chestnut and copper beech trees. In its centre is a fine Art Nouveau theatre, a stylish white building whose designer, Axel Anderberg, also designed the Stockholm Opera.
From the lakeshore in the park, boats operated by Landskapet JO leave for three-hour tours of the nearby marshes and wetlands, a UNESCO World Heritage site known as Vattenriket and renowned for its rich vegetation as well as extensive bird and marine life. Departures must be booked in advance through the website. Before boarding the boats, try to check out the bird’s-eye tour of Vattenriket shown in the Opteryx flight simulator inside the Vattenriket Naturum nature centre (daily 11am–5pm; free), accessed via the wooden footbridge from the southwest corner of Tivoliparken.
