Self-described as the world's largest model railway, the more than 10,000-square-foot Miniatur Wunderland takes visitors around the world to admire models of miniature-sized countries and cities, including Southern Germany, Hamburg, USA, Scandinavia, Switzerland and Venice. Across nine different sections are more than 1,000 trains, 130,000 trees and nearly 250,000 figures.

Recent visitors offered rave reviews for Miniatur Wunderland, saying it was appealing to both kids and adults alike. Others were in awe of the attention to detail. However, a few warned that since this is a popular attraction, it can get very crowded. Miniatur Wunderland advises timing your visit in the early morning or late afternoon to avoid the largest crowds.

The Wunderland is open daily, though hours vary day to day. Tickets cost 15 euros (about $17) for adults and 7.50 euros (about $8) for ages 15 and younger. Hourlong guided tours, which offer insight into the building and technology required, are available for an additional fee. To avoid having to wait in a long line, consider reserving your tickets online in advance. The reservation system allows you to select the day and specific time of your visit and bypass lines at the entrance. You'll find the attraction located near the Baumwall U-Bahn station.
