It's very cheap at only R$0.15, and conveniently located. It facilitates a 10 minute walk from the ferry to Pelourinho or from Pelourinho to the market. There may be a bit of a line depending on the time of day that you visit. Can also get a bit hot during the day. There are stunning views from the top, a very popular photo op spot, as well as a famous ice cream shop help you beat the heat. Can't miss it on a visit to Salvador and I definitely recommend taking it at least once.
