choose tours early, before you leave home. We waited until we were on-board the ship. Our tour was overbooked, and canceled. The ship's staff and the locals provided a mcuh shorter tour of a rookery near the port that was an amazing sample of the wild life. Remember, the population of the Falklands is small, and they don't have the normal tourist capabilities. Seeing penguins up that close is absolutely amazing, and the island itself (including meeting the local people) is delightful. We stopped at the local conservation society and enjoyed their slide show. There is a local tour to one of the rookeries available on the dock for a much smaller price than the price on-board the ship, but it only takes you to a single rookery.
we took the tour of the Tierra Del Fuego National Park. The tour was okay, but the second half, a catamaran cruise down the Beagle Channel was awesome due to the visual tours of the bird and sea lion islands. The natural beauty of the area needs a bit of time to see, and our guide wasn't that great. We were prepared for the major temperature changes that occurred (warm to windy and cold), but too many of our fellow passengers were not. We weren't interested in shopping, but there did seem to be a lot of stuff that was local origin.
