I hiked around in boots, hiking boots for the penguins and walking boots for the other trips. Be careful if you are going on the Alerce hike as it is rough going so I was told and one of the passengers twisted her ankle in hiking boots. Layering, a definate must, and as I do not care how I look on these trips, they ended up tied around my waist. I move fairly fast around these places and burn up lots of energy. The penguins were the highlight as I am a animal freak. You will not be disappointed. It was windy, windy, windy, blowing rain, and cold, but no snow or ice. It was truely a adventure. It was about a 1k hike to the penguin rookery, viewing birds all the way, and standing on the beach really hits home as to what part of the world you are in, wild.
I also hate carrying heaps of stuff, so after many many years of travelling I have come up with the all purpose backpack for the day, lots of pockets in jackets for the hikes and have an uncanny nack of carrying credit cards, ship passports, in the old favourite - the bra. My husband and I do a lot of sailing so we had light weather spray coats that roll into a small bundles and head gear really helps keep you warm. Beanies. We also had with us our heavy weather sailing jackets. These are a pain in the butt, bulky, uncomfortable and take up heaps of room, BUT, it was blowing 50 - 60 knots as we rounded the horn and they were well worth the hassel of taking them. We were travelling at the time for 2 months, from hot to cold to hot, so we travelled with 4 large wheelies, 1 suitpack and 2 backpacks and could still move all this luggage with out trolleys, amazing really. Having light and heavy weather jackets covered all conditions. It was a perfect combination. At one stage we were the only crazy ones on deck, looking outrageous screaming into movies cameras carrying on like 2 children, but the WOW factor was in effect.
We recently invested in digital cameras, still and movies, that fit into pockets. Look out for waterproof cases. Its been a fabulous investment. We use to carry large camera bags and what a hassel.
Another small tip that we did and it is a great memento. We took with us a sea charts of the area and our gps, and binoculars,(typical sailing stuff) which proved to be really fun spotting around the Cape, and through the Beagle. The Navigator of the Royal Princess was kind enough to plot our course on our charts and we now have it framed on the wall - a great memory and conversation piece.
Hope the weather is kind and you have a great cruise. Let me know how great it was.
PS - The Faulklands are fabulous.
