Packing for a big trip like Antarctica can be a bit overwhelming, but
Hurtigruten Expeditions makes it a lot easier by providing water and windproof jackets (that you can keep!) and warm, waterproof boots that you can use for the duration of your trip (you'll have to return these). A reusable water bottle is provided and optional trekking poles are available as well for hiking excursions. This saves some room in your luggage for other essentials, like wool baselayers, hats and gloves, waterproof pants, fleece mid-layers, sunglasses, a drybag, and plenty of socks. Even if you don't typically get seasick, it's key to bring something for motion sickness, such as Dramamine, sea-band wristbands, or a prescription patch. Another item that's nice to have on board, is a pair of slippers for walking around the ship's interior.
When traveling to such a beautiful and unique destination, you're going to want to have some sort of camera with you to capture the magic. Of course, our smartphones typically can do a fairly good job, but for this type of trip, having a camera with capabilities for higher quality photos and a zoom lens will get you memorable shots, particularly of wildlife. For travel, the Sony Alpha mirrorless interchangeable lens cameras are both lightweight and capable. If you're serious about getting solid wildlife images, the
FE 200-600 mm F5.6-6.3 G OSS Full-frame Telephoto Zoom G Lens is the way to go. It produces crisp, tight shots, and paired with the
Sony A 7 IV or V, has superior auto-tracking and eye recognition specifically for animals and birds. If you'd prefer a compact camera that still offers high-quality images, the
Sony Cybershot DSC-RX100M3 is a great choice as well.
