I've lived in Switzerland for 5 years. Here are the 6 biggest mistakes I see first-time visitors make over and over.

Zermatt, Lauterbrunnen, Interlaken, and Lucerne are popular, jaw-dropping locations, but they're not the only spots worth visiting in Switzerland.

Instead of only seeing the few places on every tourist's list, consider branching out to smaller, lesser-visited ones for at least a day trip. Fortunately, many are easily accessible by public transportation out of some of the area's main hubs.

For example, close to Interlaken are the mountain villages of Frutigen, Kandersteg, and Adelboden, which offer gorgeous alpine views combined with fewer crowds and more authentic experiences.

In Switzerland, dining out can seem expensive — in part because the cost of production, labor, and relevant service charges are typically already included in the price of the meal.

Personally, I find the prices easier to stomach when I remember you're often paying for high-quality, regional fare, and restaurant staff here are typically earning a fair wage.

And although tipping servers 15% to 20% of a bill is standard practice in places like the US, it's not the norm here. If you enjoyed the meal and the service, it's customary to round up a few francs or leave a tip between 5% and 10%.

Switzerland is a popular travel destination throughout the year, and its major attractions can fill up quickly — especially seats on our world-famous scenic routes.

If you plan on riding the Glacier Express or Bernina Express, book your train tickets as far in advance as possible.

However, don't fret if you realize it's too late to book a seat on a scenic route. You'll be just fine on our "regular" trains, which tend to run faster, not book up as quickly, and still offer beautiful views.

When traveling by train, it's important to double-check your ticket class and location. (And, if you have a paper ticket, get it validated.)

Signage indicating first or second class can be found both outside and inside each car. Oftentimes, the class is also noted on the headrests of the seats themselves.

Ticketing agents on board will not hesitate to issue an on-the-spot fine for tourists seated in the wrong class. In addition to a fine of about 100 francs, you'll also have to pay the difference in price for the ticket.

Also, pay attention to where your seats are before entering each car so you won't have to lug an oversized suitcase through the entire train.

Switzerland is one of the smallest countries in Europe, at about 16,000 square miles. However, I've seen tourists mistakenly assume they can just zip through and see everything it has to offer in just three or four days.

For example, Zurich may seem close to Geneva on a map, but they are actually about three hours apart by train. Sure, you could also opt for a one-hour flight — but my point is that trying to see so many cities in a short period won't allow you to truly get a feel for each.

Travel is about experiencing a place, not just visiting to check it off a bucket list. If you've only got a week in Switzerland, I suggest you limit yourself to exploring two or three cities instead of trying to cram six or seven single-night stays in new places into your itinerary.

Switzerland is composed of 26 cantons, and each of these administrative regions has its own distinct culture, government, and history. They also don't all speak the same languages.

Although you'll find English speakers throughout the country — especially in popular tourist areas — Switzerland actually has four official languages: German, French, Italian, and Romansh.

It's helpful to learn a few basic greetings in those major languages and ensure you use them in the appropriate region.

Also, it's handy to become familiar with some of the commonly used symbols — especially when it comes to trash cans.

The Swiss are conscientious recyclers, so take a beat to look up the symbols printed on the bins before tossing something in them if you are confused. Your mindfulness will be appreciated
