Denver has become a popular tourist destination thanks to its rich cultural history, thriving brewery scene, stunning parks and more. But visitors to the Mile High City dont always know how to get the proper experience and many make their fair share of missteps.

We asked Denver locals to share some of the faux pas theyve observed. From packing the wrong outfits to underestimating the effects of the high altitude, here are 16 mistakes tourists often make while visiting Denver and some advice for avoiding these errors during your travels.

Spending all your time indoors

Dont stay indoors, opt to go outside. We love our outdoors and you will, too. Hop in on a game of volleyball at Wash Park (Washington Park), or play a round of golf at one of the many courses throughout the city. There is something for everyone. So before you book a museum each day, consider a day outside. Breanna Phippen , blogger at Bites with Bre

Not taking the altitude seriously

Dont underestimate Denvers altitude. Denver has an elevation of 5,280 feet, making us closer to the sun. Your body will need time to adjust to the altitude, which will affect working out, hiking and drinking. Make sure to pace yourself, stay extra hydrated, wear sunscreen and know that headaches and nosebleeds can happen while visiting the Mile High City. Jamie Lee, blogger at The Denver Housewife

Book yourself a float tank, IV therapy or both. Your body will thank you. The altitude is no joke and can affect anyone. Sip your adult beverages slowly and dont expect to hit any personal records in your fitness. Phippen

Going out without layers

Going out in the late afternoon without layers is a mistake when traveling in Colorado, particularly in the early spring and late fall. The air feels much warmer than the outside temperature from the sun, so youll be comfortable wearing a short sleeve or tank. However, as soon as the sun goes down over the mountains, it instantly feels much colder and youll want a jacket. Shelby Elmore , a marketing professional

Denver is known for its uncertain weather. We can often see all four seasons in a day or week. Pack layers for your trip since it can snow until the middle of May, and heavy afternoon downpours and hailstorms are normal during summer afternoons. Wear comfortable shoes, hats, sunscreen and layers because you never know how the weather will change during the day. Lee

Wearing uncomfortable footwear

Consider your footwear. Ditch the dress shoes or high heels for Birkenstocks and gym shoes. We appreciate the laid-back style, and the majority of bars, restaurants and even clubs require casual for their dress code. Phippen

Disregarding cyclists

Share the road. We are a bicycle-friendly community. Road cyclists will always choose the bike lane, but remember they have the right to the full car lane. Its also easier to get around the city by bike, scooter or foot, so ditch the car rental. Phippen
