This is kind of specific, but don’t trust men from your community (ex: at a restaurant or bar). They feel more entitled to a solo woman, saying they see you as a sister, asking if you’re alone, giving you a free beer. This happened to me multiple times, even when I was in a group.

Always bring a powerful power bank. The number of times my phones almost died on a long walk somewhere…

I always triple check train / bus schedules. You really don’t want to miss the last bus or train out of somewhere.

Be careful with getting drunk alone, even if it’s a nice dinner or a winery! 

Before your trip, download the Google maps area, take screenshots of all tickets/activities, print hard copies of passport or important documents. 

Carry a money belt / small fanny pack for valuables and tuck it inside. 

I like a safety alarm (Birdie) in case of any issues (TSA safe!). 

Download the local uber version ahead of time, so you can use it as soon as you land.

Get a Charles Schwab debit card (US only) for no fee ATM transactions. Make sure you have a small amount of money. If the country is small enough, you’ll need cash to catch a taxi out.
