This is a private walking tour in Porto, and we understand that the city is quite hilly. However, we can customize the pace according to your needs, and take as many breaks as needed. If you need to rest or take a break, simply let your guide know and they will be happy to accommodate your needs. We can also stop for coffee or refreshments at any time during the tour. Our goal is to ensure that you have an enjoyable and comfortable experience exploring our beautiful city! 🙂
