We arrived in Ushuaia on a cruise ship traveling from Rio to Valparaiso, and had planned in advance with five other passengers (with whom we'd connected online via the cruise critic website) to take a private van tour of Tierra del Fuego National Park with Edgardo Calaio [edgardo calaio at gmail dot com]. Edgardo is a wonderful, experienced, young guide, with a university degree in tourism, and particular interests in nature and photography. He met us at our ship, and as we rode to and through the Park in his very comfortable van, he told us (in a pleasant low-key way) iabout Ushuaia and Tierra del Fuego. In the Park, he took us to the major sights, inclding the bay where the (true) Post Office at the End of the World is located on stilt posts out over the water. (We had our passports attractively stamped there.) We also visited a small, free, museum at a spacious lakeside cafe, where we learned about the original inhabitants. Our final stop was at the famous sign marking the end of the Pan American Highway which runs about 30,000 miles from Northern Alaska to Tierra del Fuego. (We were lucky to arrive at the same time as an adventurous Danish couple who took 7 months to ride the whole highway on motorcycles.) The park is a peaceful natural place of lakes, greenery and mountain views. We were fortunate to see a peregrine falcon, a stunning kingfisher, and some unusual swans with their young.). Though this was high summer (January), the place has extremely harsh winters and not many species make home there. After our visit to the Park, Edgardo took us to the town and pointed out some interesting shops at our request (we purchased chocolate, crafts, and wine). For those wishing to see other sites, Edgardo also offers a 6-hour tour to Fagnano and Hidden Lakes (across the Andes), and a full-day tour, combining all of the above. Our 4-hour Park tour was engaging, relaxing, and a great value.
