I was skeptical that it would be a bit boring, but it was a nice 45 minute tour of the harbour. Not too pricey. We saw lots of dolphins and the tour guide used to work on a ship for 20 years and told us interesting facts about Del Monte, the "ghost" on the hospital stone, car import/exports. We got a pleasant rain and the breeze was lovely. I haven't tried the other tour companies but we all had fun, despite having to wear the dust masks. The company offered a free appetizer at Fishermans' Wharf. Do NOT go- it is overpriced cafeteria food. The waitresses and hostesses are not very friendly, either. They probably have a deal with the restaurant so they are obligated to offer a coupon but don't do it!!
