Lukas was a fantastic guide - he was knowledgeable, kind, and always made sure that we were comfortable and well cared-for. The Rock Cities of Bohemian Paradise are one of the greatest works of natural beauty I've had the pleasure to experience, and I can hardly capture in words what I certainly did not capture in photographs. The hike through the Geopark took us up, down, through, around, and over the many varieties and layers of sandstone rock and loamy pine-needle covered forest floors. After our hike we had lunch at a small local hotel, where we enjoyed some authentic Czech cuisine before visiting Kost Castle. We returned to Prague via van later in the day, tired and full from the adventure. I can't highly recommend the experience, or our guide Lukas, heartily enough.
