One of the best ways to find hidden gems in Prague Old Town is to wander. Do not be afraid to enter open doorways that look like private halls. Often, they lead to beautiful courtyards with centuries-old trees. These spots provide a cool escape during the hot summer months. You can find more information on the Prague tourism portal.

Practical Tips for Your Old Town Visit

Visiting the Old Town requires some planning to avoid the worst crowds. Most large tour groups stay on the main Royal Route. If you step just one block away, the atmosphere changes instantly. Early morning is the best time for photography and quiet walks.

Wear comfortable walking shoes because the cobblestones are very uneven. Many of these hidden spots have restricted opening hours. Always check the official websites before you head out. This is especially true for the smaller museums and private chapels.

Public transport is excellent, but the Old Town is best explored on foot. Use the Staroměstská or Můstek metro stations as your starting points. Keep a map on your phone, but allow yourself to get lost. Getting lost is often how you find the best secrets in this historic city.
