The Góra Parkowa funicular railway is a fun family outing. The bottom station is near the northern end of the promenade in Park Zdrojowy, and cars depart every 15 minutes. The 142m ascent takes under three minutes. At the top you’ll find pretty views in all directions, a giant slide and a tubing run for kids.
If it’s a nice day, buy a one-way ticket and hike back down through the park to town.
