Taking the polar plunge in Antarctica is one of the most unforgettable experiences you can enjoy on an expedition cruise. It's certainly not for the faint of heart, but if you're into thrilling, once-in-a-lifetime activities in extraordinary destinations, you could not challenge yourself with a more worthy experience.
Antarctica is one of our planet's most extreme and remote environments, and immersing yourself in its frozen waters is an adventure like no other.
Since we field so many questions about this incredible activity, we thought we'd compile a comprehensive polar plunge guide – The following is all you need to know about taking a plunge in the icy waters of Antarctica comfortably and safely and taking home memories that'll last a lifetime.
What is a polar plunge?
Akin to an extreme ice bath, the polar plunge is an exhilarating activity where you jump into (or gently enter) the icy cold waters of Antarctica. Yes, it can be as painful as it sounds, but this challenging activity is one of the most exhilarating and rewarding experiences on Antarctica expedition cruises.
Why take the polar plunge? The science of cold-water immersion
Proponents have long touted the benefits of cold-water immersion, and science is proving them right. Not only do you get an immediate adrenalin and endorphin rush when you plunge into cold water, but you also develop an overall feeling of euphoria that lasts for hours. Usually, everyone's quite apprehensive before they take their plunge (because of icy waters!), but completing a polar plunge also triggers an incredible sense of accomplishment, and those happy hormones can last for days.

Can anyone do the polar plunge?
Cold water immersion can be quite shocking to the system because, when all is said and done, we are not Adelie penguins. Our bodies aren’t built for icy swims – regardless of what the Scandinavians may say!

A polar plunge temporarily plummets your body temperature and makes the heart work harder than usual. It also needs to do this very quickly. If you have any underlying heart condition, lung or blood pressure problems, it is highly recommended you get the all-clear from your doctor before attempting a polar plunge on your Antarctica expedition. Note that you plunge at your own risk, so be well aware of your medical history before you try it and speak to the resident ship doctor if in doubt.
It's worth noting that even super-fit and healthy individuals can fall prey to the cold-shock response unless they are accustomed to swimming in freezing water. That's why a safety protocol is in place when cruise guests take a polar plunge in Antarctica.
What to expect on a polar plunge
The main message from all those who have come and plunged before you, is that the whole ordeal is over in a flash. Yes, you plunge and gasp, but you are also plucked out of those freezing waters before you know what's happened.
Phew, made it!
1, 2, 3…JUMP!
Safety
When expedition ships organize a polar plunge, safety is the #1 priority. Not only is there a doctor in attendance, but you will be attached to the ship by a rope and waistband – so don't worry, you won't plunge too far. An inflatable Zodiac will be right there to rescue you if you can't manage to get back on the ship on your own. When you take the plunge, everyone's eyes are on you – not only to shout out encouragement (which helps!) but also to ensure you are always safe.
Polar plunges are typically offered once on every Antarctica expedition cruise. Captains check out conditions daily and choose the most favourable place and conditions. Sometimes, you'll cannonball straight off the gangway or from a Zodiac. At other times, you can head off for a plunge straight off a beach. This is slightly better for the body as your immersion won't be as immediate as on a dive, yet it feels much harder to keep walking into those freezing waters.

Camaraderie
Taking a polar plunge is an adrenalin-pumping activity even before you plunge. The camaraderie builds as you wait in line with fellow plungees, all extremely excited and donning fluffy robes. The anticipation peaks as the first person plunges, and the excitement rises with each subsequent dive. Those shouts of encouragement are just what you need to drown out your inner voice that says, 'Don't do it!'
But plunge you do, and wow, what a thrill. You'll be back on board, warm, toasty and elated for hours afterwards. Honestly, we've never had any guests do the polar plunge and regret it – it is one of the most recommended experiences of all the fantastic activities on Antarctic expeditions.

How cold is the water in Antarctica in summer?
We’re not gonna lie, the sea of Antarctica is freezing cold even in the heart of the southern summer. Sea temps usually range between -2 C and 2C. Most experienced polar plunges will say that you won’t actually feel much difference between those two temp ranges, so there’s always that consolation. Due to the high salt content of the sea, you won’t need to break through ice, so the difficulty of a plunge only comes down to your mental resolve.
Where can you do a polar plunge?
Not all cruise ships headed to Antarctica offer the polar plunge, but usually, all expedition ships carrying only 200 passengers do. Look for cruise ships that specifically mention it among their offered activities – that’s the best way to know for sure that it’s on offer.
Remember that conditions must be just right for a polar plunge – so although every expedition ship captain will endeavour to make it happen, it is never 100% guaranteed.
How much does a polar plunge cost?
Courage is the only thing a polar plunge in Antarctica will cost you – the activity is free to those brave enough!
Insider tips on taking your polar plunge
- Know your medical history – This is very important. The polar plunge isn't for everyone, so make sure you don't have any medical conditions that might preclude you from a swim in freezing water
- Wear what makes you comfortable – Most people take the polar plunge in their swimmers but feel free to wear shorts and a t-shirt if it makes you feel more comfortable in a crowd. Although easier said than done, it's important not to overthink it too much – once you've decided to plunge, don't double-guess yourself and JUST DO IT.
- Stand around a minute or so in your swimmers – Some say there's no need to freeze before you enter the water, so keep your clothes/robe on until the very last second. Yet there's a logic to acclimatizing just a little to the cold before jumping in. The air temperature will likely be similar to the sea, so it won't be such a shock if you are already standing around half-dressed.
- Plug your nose – Keep a firm grip on your nose as you dive to take in less seawater, or just forget about all that and do a silly jump for the cameras!
- Join in the fun – The polar plunge is undoubtedly one of the highlights of Antarctic expeditions, even if you're not diving in. Join the supportive crowd and have a ball, the whole thing is entertaining, even as a spectator.
- Dive or slide – Doing what makes you feel more comfortable is essential. Some people really do cannonball right off the ship while others prefer to enter the water more gingerly. Let your experienced guides know what you prefer, but listen to their recommendations – they know best!
- Keep warm – Everything will be set up to warm you as soon as you exit the water – listen to your guide's instructions and change into warm clothing ASAP. Enjoy those post-plunge celebrations and soak up the high!
