Free guided tours run daily and take about 45–55 minutes; no reservation needed for small families. The dome observation deck (seasonal) offers sweeping views of Madison’s isthmus and both lakes — kids love it. Indoor and climate-controlled, ideal for cold or rainy days. Arrive 10 minutes early; strollers must be folded for the elevator in some areas.
