The entry fee without the Tallinn card is 3 Euros for an adult. The climb up to the highest part of the tower gets quite narrow, and it is ideal that you have both hands available to support yourself up the high and narrow stairs. At one point, if you'd like to go up the highest part of the tower, past the viewing platform, the guide rail is made of swinging rope. The passage can only accomodate one way of traffic - so if you are descending, make sure no one is ascending at the same time, or you'll both be stuck. The walk along the platform is easy and offers a great view of the town below. There is only so far you are able to walk, but the walk will give you a good idea of what it would've been like to patrol above the city. The wall is well preserved and there are small descriptions on display inside the tower to describe what you're seeing.

Found it cool. Was a bit pricey (3 euro) for a cool view in a ancient environment.

Climb this 14th-century tower and stroll atop its 200m stretch of Town Wall for fantastic views of Tallinn's medieval defences. The three-storey tower, which stands adjacent Müürivahe street next to Old Town's knit market, dates back to the 14th century and at different times was used as a prison and a weapons store. Nowadays it serves far more peaceful purposes: in addition to being a curiosity history-minded visitors, it houses an art gallery.

Nice place to see the old town of Tallinn. Entrance fee is 3euro only at 2017.

Brilliant views - well worth a visit
