A
Antarctica is one of the last untouched frontiers on the planet. Despite its tough conditions, an Antarctic trip is far less dangerous nowadays than in the past. Here are the most popular routes to Antarctica, with different start points, pathways, and modes of transportation.
1. Ship tour from Argentina
Departing from Ushuaia is the most popular route when going to Antarctica from South American ports. Ushuaia is situated closer to Antarctic Peninsula (半岛) than other departure points, hence you can have more time spent on the scenic peninsula admiring icebergs, glaciers and abundant wildlife. There are a variety of ships from Ushuaia to choose.
Duration: 6 to 24 days
Cost: Between USD 6,000 and USD 25,000
Good to know: If you still want to visit some other incredible South American destinations, some suggestions are the Galapagos Islands, Rio de Janeiro and Machu Picchu.
2. Fly-ship tour from Chile
If you want to avoid spending two days crossing the Drake Passage and encounter rough seas in the bad weather, you can choose a fly-ship package. This involves flying to King George Island, which is right off the west coast of Antarctica Peninsula, to join a ship trip. You can also go ashore to experience the same sightseeing and wildlife opportunities.
Duration: 8 days
Cost: Between USD 10,000 and USD 15,000
Good to know: If you have limited time and do not wish to spend more time on a ship than is necessary, then the fly-ship option is ideal.
3. Ship tour from Australia or New Zealand
Although you are unlikely to encounter any other ship all the way, you will see huge icebergs, Mount Erebus (an active volcano), emperor penguins, scientific bases and the sites of historic 20th century Antarctic adventures. If you are looking for a feeling of vast isolation and remoteness, this is the trip to take!
Duration: 26 to 30 days
Cost: USD 16,000 and USD 30,000
Good to know: Ships departing from New Zealand and Australia are smaller and carry no more than 50 passengers. These trips are rare and should be booked well in advance.
