Airlines canceled more than 750 flights into and out of Denver Wednesday ahead of aspring blizzard, and the travel pain is expected to spread to other cities as the potentially historic storm moves into the upper Midwest.

Southwest Airlines and United Airlines, which have major operations at Denver International Airport, each canceled about 200 flights to and from Denver, according to flight tracker FlightAware. That’s about half of their scheduled Wednesday flights. Regional airline SkyWest, a feeder carrier for United, canceled 158 flights, about half of its scheduled flights. Frontier, which is based in Denver, has canceled 39 Denver flights.

The Denver cancellations are already spilling into Thursday, with 175 flights to and from the airport canceled as of 6:45 p.m. EDT, according to FlightAware. That number is expected to grow as the storm develops.

You don’t have to be flying to or from Denver to be affected. Southwest and United connect a lot of passengers through Denver, so travelers are urged to check their flight status before heading to the airport.

Airlines have been allowing travelers to change their flights to avoid the storm, dubbed Winter Storm Wesley.

Policies vary by airline, but in general the waivers allowed affected travelers to change their flights without penalty.

Passengers whose flights are canceled are eligible for a refund even if they bought a nonrefundable ticket.

We’re talking about places that make you look at their high ratings and think, “Really? There?”

For example, one of the highest rated tourist attractions in Cornwall, England is a tunnel leading to a supermarket. Another highly rated attraction, this time in California, is an alley were people have stuck used gum over the years. Or, there’s the Prada store that’s literally in the middle of nowhere. Even better, there’s a room full of dirt in New York City that people apparently really enjoy.

These places may not have obvious appeal to the casual TripAdvisor user. But for those who’ve gone to these places, it’s easy to see why they’re so special. Just take a look at the reviews and you’ll see that there are people in the world who go gaga for the seemingly everyday, mundane, or just plain odd attractions that you may not even have bothered to stop for.

They may not be world renowned restaurants, important, historical landmarks, or prestigious museums filled with fine art, but these places might be good to put on your travel bucket list. Especially if you’d like to go off the beaten path once in a while.

Don’t take our word for it, check out the reviews.

Baldwin Street, the steepest street in the world — Dunedin, New Zealand: 4 stars

Move over, San Francisco. You’ve got nothing on Baldwin Street. This road actually still holds the Guinness World Record title for the steepest street in the world. So, if you’re a world record enthusiast, it’s easy to see why this place has four stars on TripAdvisor. One reviewer who rated it five stars, said, “It is what it says. It’s steep!”

Bude Tunnel — Cornwall, England: 5 stars

With over 480 five-star reviews, this tunnel is the highest rated attraction in Cornwall. It’s not a special tunnel at first glance; It just connects a supermarket parking lot to a main road. But occasionally (especially at Christmas) it is decorated in colorful lights. Reviewers have called it the “8th wonder of the world” and an “amazing, magical experience.” Plus, it’s free to experience.

The Gnome Reserve and Flower Garden — West Putford, England: 4.5 stars

Nature lovers can easily enjoy this beautiful garden that’s perfect for walking around on a nice, spring day. But what makes it special (maybe even a little strange) is that it’s also a gnome “sanctuary,” where dozens of little gnomes populate the grounds. It’s quirky, to say the least. “I defy anyone to come here and not to smile. It is a little oasis of happiness and innocent joy,” said one reviewer. It also has a TripAdvisor “Certificate of Excellence.”

Carhenge — Alliance, Nebraska: 4.5 stars

Anyone who has driven through Nebraska knows there isn’t too much to see. But, there is Carhenge, a replica of Stonehenge, only made with cars. While it seems like a typical roadside attraction, it’s actually a pretty impressive sight to behold. Carhenge is actually created with old, vintage automobiles, and looks like a fascinating piece of art in the middle of the Plains. “Carhenge is a wonderful take on Stonehenge. Sure, it is a tongue-in-cheek take, but it is kind of impressive,” said one reviewer.

Bubblegum Alley — San Luis Obispo, California: 3.5 stars

This one is just what it sounds like: an alley filled with gum. But it’s not exactly a candy store. Bubblegum Alley (rated 3.5 stars, so it’s very good but not for everyone) is famous in San Luis Obispo for being a place where people have been sticking their used gum for years. But the result is actually pretty fascinating (and colorful). “Yes it’s an alley with gum. That’s it. Would be interesting to know history. That being said I found it colorful, interesting and strange. Of course I took some gum and stuck it on the wall,” one reviewer said.

Hole N’ The Rock — Moab, Utah: 4 stars

Hole N’ The Rock looks like it might be a natural wonder (aside from the big, painted sign) when you’re driving past, but it’s actually a unique home that was carved into the rock in Utah’s Canyonlands Country. Now, it’s a nice little gift shop, petting zoo, and trading post where you can take tours all year. One positive reviewer called it “ultimate hokiness,” which we’re going to assume is a good thing.

Few expenses sneak up on you as deviously as international cellphone charges. But telecom rates don’t have to be exorbitant if you do a little homework before you travel.

Start by talking to your own provider to see what’s covered. As companies update their phone plans, features get added and changed, resulting in benefits to current customers that they might know nothing about.

If you have an iPad with an Apple  SIM, you can browse cellular data plans from select carriers in almost 100 countries and regions worldwide. You might be able to buy a SIM card for a specific country before making your trip.

Want cheap data and phone calls when you’re abroad? Here’s how.

With each passing year, more American women (and women in general) are choosing to travel solo. Traveling alone as a woman can be daunting for first timer’s, but also thrilling and memorable.

If you’re not a seasoned traveler and are considering setting off on your own for the first time, you’re probably wondering where to go. Here are five of the safest countries in the world for women traveling alone, whether you’re traveling on foot or by plane.

Australia

Australians are strong supporters of the “gap year.” The “gap year” is the year after graduating college that is dedicated to traveling around the world. Other countries have this custom but Australia really takes it to heart. It’s never too hard to run into young Aussies, especially women, traveling abroad.

By the same token, Australians can readily empathize with others who travel to their country. The people down under are very relaxed and laid back. Women are well respected there and usually have few problems. Consider looking into a car hire and doing a road trip on the Great Ocean Road.

The Netherlands

The Dutch are very well behaved and quietly classy people. They believe that women should be independent, thus there’s very little harassment that takes place. English is widely spoken in larger urban areas and to some extent in rural areas as well.

The Dutch are quite friendly folk and there’s no better way to interact with the locals than by joining one of their favorite pastimes: bicycle riding. There’s nothing like riding along a dyke path, through tulip gardens, as windmills loom in the distance.

Canada

America’s neighbor to the north has far less crime. The exchange rate is about even and most of Canada is pretty affordable. Canada may not be the most exotic location, but its proximity to the United States and shared culture make it a safe, comfortable place to visit. Cities like Toronto, Montreal and Vancouver are cosmopolitan and offer a wide variety of culture.

If that doesn’t suit you, try hiking along the breath taking trails of the Canadian Rockies. In years past, Americans have been known to travel abroad with maple leaf and Canadian flag stickers or patches on their personal belongings to avoid trouble. That by itself tells you everything you need to know about Canada.

Ireland

The Irish made their reputation by being extremely welcoming and very hospitable. Their friendliness, iconic landscapes and heartwarming pubs where the Guinness perpetually flows isn’t the stuff of lore. That said there’s no stigma attached to women drinking in Ireland like in other countries. Combine that with the gregarious nature of the Irish and you’re bound to find a memorable time.

If you’re a bit shy, try doing a bed and breakfast circuit. The Irish relish the opportunity to introduce you to their culture, but also to their people. Staying at a bed and breakfast will allow you to meet locals, as well as other travelers, so you won’t ever be alone, unless you want to.

Costa Rica

Costa Rica is one of the few countries in the world without a standing army. Do you need another reason to go? Despite many Latin American countries suffering from men who are too forward, Costa Rica refreshingly stands apart. Costa Ricans are calm, cool people that enjoy pura vida, or “the good life.”

Women can shop at the markets there without fear of being scammed or ripped off. Aside from the endearing nature of Costa Ricans, the country boasts some of the best ecotourism in all of the Americas. With a number of different climate zones, you’ll never be bored as the flora and fauna is astounding. The country also offers a dizzying amount of sports, from whitewater rafting, scuba diving, horseback riding, zip lining, surfing and many more.
