• A runestone map to download before you go (the "A Rune Stone Walk in Sigtuna" pamphlet), which turns the old town into a treasure hunt
• Short museum hours: noon to 4pm most of the year and closed Mondays from November to March, so plan the town walk around them
• Klockbacken hill in the town center has walking paths, a barbecue area and sledding in winter

Sweden's first town, founded around 980, still follows its old street plan: Stora gatan runs three meters above the original main street. Kids can hunt for runestones (no town has more) and explore three medieval church ruins.

Sigtuna Museum covers the Stone Age to today, with a trail for kids. On the lakefront, a 12-hole adventure golf course has each hole modeled on a historic place in town.
