At times, travelers are overcome with the thrill and excitement of going to a foreign place for the first time. Places like Italy, Berlin, Rome and London are where one can easily get lost in the diverse beauty, culture and history. These in turn can lead to fatal mistakes tourists wished they could've avoided early on.

Here are some of those biggest traveling mistakes one must 100% veer away from, especially when going to Europe.

1. Arriving at the airport less than 2 hours before departure.

Travelers need to keep in mind that they're not in for a domestic flight that they can easily breeze through human traffic in the airport and arrive for check in less than 2 hours before their flight.

Airports like Heathrow Airport can be like hell. Queues are always long and people move from check in to their gate as if they are covering an entire football field. This is why it's strongly advised to be present at least 3 hours before one's departure because everything else in the airport will burn time.

2. Choosing bus tours over walking/biking tours.

London's traffic can be so bad. Travelers who opt to ride a double-decker bus for a tour around the city ends up getting stuck amongst cars, listening to recorded tour guides.

It is best to go for free walking tours, which are rampant all across the continent. Travelers can also rent their own bikes for minimal costs and cycle around the picturesque tourists spots of Spain, Italy and Germany.

3. Forgetting to look before crossing the street.

Driving lanes and pedestrians vary from one country to the next. In London, there are numerous vehicle-related accidents because majority of the victims are tourists who didn't know that traffic comes from the opposite direction.

Two words: Look right.

4. Going to far too many museums that one can handle.

Paris and Italy are packed with museums anyone can easily go crazy for. Travelers end up with overly ambitious itinerary that include three our even four trips to the museums in one day.

The cardinal rule of traveling is to limit the museum visits to at most one a day, to truly bask in each of the museum's unique beauty and history. Otherwise, everything else will look the same and exhausting.

5. Skipping ticket validations in regional rides.

Regional trains don't contain assigned seats and time. This makes necessary for all travelers to validate their tickets before boarding any ride. It's become such a common yet very expensive mistake among tourists, having to end up paying for fines that could've been easily prevented.
