If you have some time for a walk, there are two viewpoints worth a visit. One is just over Mehmed Paša Sokolović Bridge. Cross the river to the West, you'll see a bus stop and the stone wall behind it. Walk the small street to the right of the wall and you'll find how to get to the top. There's a zipline on the top. The other viewpoint is farther away, but it's more visible from below. Look at the direction of the church and you'll see a green hill with a Russian cross on the top, to the South of the city at the river. To reach the place go towards the church, pass it and then navigate your way up (partially via a path and lawn). The view from the top is breathtaking.
