• I've spent years traveling to 94 countries which has taught me some great money-saving travel tips.
• I don't pay to check a bag when I travel, and I seek out free activities, like walking tours.
• I get cash when I'm at my destination and use credit cards without foreign transaction fees.

I've been traveling full-time for nine years.

Throughout my trips to 94 countries and all seven continents, I've learned a lot of ways to save money abroad — some through trial and error.

Here are four ways I save money when I travel to another country.

Get the best deal on local currency

I don't travel with cash unless I'm going to a destination where it's difficult to access ATMs. Generally, converting money before a trip is more costly than withdrawing local currency from an ATM.

I find it's best to use a debit card from a bank that doesn't charge international transaction fees, honors market-based exchange rates, and reimburses ATM cash withdrawal fees. I've had good luck with Charles Schwab.

I also try to withdraw cash from ATMs associated with a bank, which can feel more secure than others in more random parts of a city.

When doing so, I also reject the bank's money conversion (also known as dynamic currency conversion). That way, I'm able to withdraw cash but at the market conversion rate, which is almost always a better deal than the bank's.

If you plan to just use your credit card abroad, make sure it's with a provider that doesn't charge international transaction fees, such as Capital One.

Seek out free activities

Many destinations around the globe have an abundance of free experiences that are enticing to tourists.

Check local publications to see what free events are happening during your visit. Some libraries have movie screenings, museums often have days with free admission, and accommodations may come with complimentary yoga or dance classes.

I also check sites like GuruWalk and SANDEMANs, which offer free local walking tours around the globe. I've gone on GuruWalk tours in places like Turkey, Tunisia, Jordan, Egypt, Estonia, and Uruguay.

Although these tours are free, don't forget to tip your guide.

Be a carry-on-only traveler

Committing to being a carry-on-only traveler has saved me a lot of money.

Paying extra for a checked bag can add up quickly — especially if you're visiting multiple destinations on your trip. And with just a carry-on, you can limit your spending by having limited space to pack souvenirs.

Be sure to check the size restrictions and weight limit for carry-on bags. Some budget airlines only allow about 15 pounds, though you can sometimes pay a minimal fee to double the weight limit.

If you can't manage with just a carry-on, fly with an airline that allows you to check your first bag for free.

Take advantage of tax rebates for foreigners

Many countries offer travelers a tax rebate for select purchases made with a foreign credit card. In Thailand, for example, certain purchases over 2,000 baht are eligible for a tax rebate.

Find out what the limit is in your destination and look into requesting a Global Blue tax refund. Keep in mind that some countries may require you to show purchased goods to an agent at the local airport.
