We had a great time on the Sophia walking tour! The free tour brings the city to life and helps to acquaint yourself with the walking layout of the town. The guides are very knowledgeable, share great stories and speak very good English. It is a free tour but bring a little something for a tip to keep spreading the love of this tour. Bring a water bottle to fill up along the way or stop half way in the park to grab a snack from one of the venders along the way. It’s not an official stop but you can quickly buy something and rejoin the group.
