Prague Castle is stunning and its surroundings is huge. The route to the castle requires a bit of walking but the great location of the castle provides spectacular view of the city. The recommended length of visit would be a few hours for anyone who would like to explore all areas of the castle and I would advise to go early in the morning to avoid the crowds. I had decided to forgo the St. Vitus Cathedral tour due to the massive queues but had a wonderful time strolling around the castle despite the not so great weather. The surroundings of the castle are perfect for photography and I had over a hundred pictures taken there during my visit.
