If you're unfamiliar with the native language of the country you're visiting, index cards can be your best friend.

Before I travel, I always write down common questions and sayings on index cards in the native language to make communication easier. Write the questions or sayings in the country's native language on one side and on the side, write the English translation. (This way, you don't accidentally ask the taxi driver where the ladies room is.)

Things you should include on your card include asking about bathrooms, police, hotels, and any other issues you think you may face. Also, be sure to write down your allergies, medical conditions, and medications.

When you're on a cruise, you'll probably find yourself spending time getting some sun on the deck. Many passengers decide to leave their room key on their lounge chair when they're swimming in the pool. This leaves your room key available to everyone who walks by.

Get a key chain necklace and put your room key on it. Wear this around your neck at all times to avoid losing it or having it stolen.

Hiking is, of course, a common outdoor sport and leisure activity, enjoyed by millions of people every day. However, there are several hiking trails throughout the world that only the bravest would attempt. They're dangerous and are only meant for the most adventurous of people (or the craziest!). The videos below provide a glimpse into seven of the world's most dangerous hiking trails. Pull on your gloves, your hiking boots -- and your Brave Hat! -- and check these out.

A hike through Spain's El Caminito del Rey ("The King's Little Pathway") is not for the faint of heart. In fact, the narrow pathways, incredible height, and sharp rocks below are the stuff of nightmares. I don't know how the person filmed and walked at the same time.
