Even though we did this walk in the winter, it may be nice at any time of the year. The only part which is tricky when it is slippery (rain or snow) is the very sharp descent from the Stradonické oppidum to point 6. That part is definitely not passable with bicycles!
The best place to start is at the railway station Nižbor, where you can easily park if you plan to have a lunch at our favorite restaurant Zastávka, owned by the Czech Paul Newman Tomáš Hanák. Railway connection to Beroun is quite frequent, so you may combine this train trip with the visit of the old town Beroun.
After walking through Stradonice along the Berounka river, you should not miss the sharp turn uphill at point 2. On your left-hand side, you will see the Stradonické waterfalls at point 3. These waterfalls are quite a lot smaller than Niagara, but their fame stems from their orange color caused by a high content of iron in its water. At point 5 you will join the interpretive walk about the Celts and their way of life. This Celtic oppidum was built here in the middle of the 2nd century BC.
