When the harsh Arctic wind gets too much, an afternoon cookery lesson or a spot of beauty therapy is an antidote. Complimentary treatments are on tap and my freshly painted hot pink nails will no doubt attract the bears’ attention. Unfortunately the cacophonous chitchat and laughter from the 14 women on the expedition scares the bears away.

Oh, did I forget to mention this is a ladies-only escape? For one week in the polar bear calendar, women are invited to Dymond Lake to get in touch with their wild side. And boy were we wild. Ronnie ran morning yoga sessions and country line dancing lessons. Susan led power tundra walks.

Wendy coaxed us out of bed at midnight to see the Aurora Borealis. Happy-hour blueberry Martinis induced some highly entertaining antics, including Orla’s spontaneous Irish dancing and Ronnie’s flat-chested Dolly Parton impersonation.

In all of this fun and frolicking, the serious issue of global warming looms large. After all, we are women with a mission to see polar bears, the unofficial poster child for climate change. I questioned whether travelling to the Arctic could be justified, if my carbon footprint will be indelibly marked on the landscape. Am I (and the environment) going straight to Hell?

Our guide, Ian, insists “the more people see bears, the more they want to protect them”. As I hadn’t yet seen a bear, I had to take his word for it. One thing is certain: global warming affects the bears’ migration. Bears get on to the ice later, which means they are leaner, weaker and less likely to survive till the spring thaw.

Overall the Arctic population of polar bears is stable, between 20,000-25,000, but predictions for the future are concerning. I was surprised to learn that polar bears are a threatened, but not endangered species. Polar bear hunting is a legal (albeit highly controlled) activity in certain territories, and Native Canadians are given hunting privileges in accordance with their heritage and experience.

Despite the hunting, one way polar bears may survive is through crossbreeding with their distant cousin the grizzly.

There’s no doubt bears – preferably alive – are good for business. Our final stop is Churchill, the “Polar Bear Capital of the World”. Hotels, restaurants, bars and gift shops in the town of 900 people are liberally decorated with bear motifs.

After our jaunt at Dymond Lake with not a bear in sight, we were keen to go even wilder and board a tundra buggy. A cross between a tractor, a moon buggy and a bus, the tundra buggy is eco-friendly, camouflaged white and specially built to cross the rocky terrain of the Arctic. It was a surprise, then, that we broke down an hour into our expedition.

Needless to say there’s no AA in the Arctic and we gals didn’t want to ruin our manicures by pushing. Eventually we were rescued by another buggy, hosting a team from the charity Polar Bears International (PBI). Our misfortune turned 180 degrees, and PBI volunteers regaled us with tales of the conservation and research work they do around the world.

And yes. We saw polar bears. Three, to be exact. The moment we pulled up along a bank of tundra scrub and first saw a bear serenely sitting, watching, waiting for the ice to freeze was awesome. Gasps were followed by eerie silence. We knew we were privileged to witness nature at her wildest, rarest and most beautiful.

I was amazed at the bears’ calm curiosity. Their stature and rippling muscle as they walked across the tundra. Their tiny ears and eyes. Their webbed feet and humped back and yawning stretches.

It was a life-changing moment, and Ian was right. Now I’ve seen polar bears in all their power and vulnerability, I definitely want to protect them.
