Key West is one of the most vibrant and laid-back destinations in the United States. With its turquoise waters, historic architecture, and unmistakable island charm, it’s no wonder so many travelers dream of visiting. But whether it’s a first time trip to Key West or you’ve been before, there are a few pitfalls you’ll want to steer clear of. In this Key West vacation guide, we’ll break down some of the most common mistakes to avoid in Key West, plus Key West travel tips that will help you get the most from your island getaway.

Planning a Trip to Key West: 15 BIG Mistakes to Avoid
Mistakes #1: Not Booking Accommodations Early Enough
Planning a trip to Key West at the last minute can lead to sticker shock. Accommodations in Key West fill up fast, especially during high season! This season runs from December through April, with extra emphasis on Spring Break.
Waiting too long often leans overpaying or settling for a hotel far form Old Town. Book months ahead to secure your ideal stay at reasonable rate. And here’s a travel planning tip for Key West: aim to stay near Duval Street or in Old Town for easy access to attractions and nightlife.

Mistake #2: Assuming You Don’t Need a Car
While Key West is a very walkable island, many visitors regret not having a car when they want to explore nearby islands or attractions like Bahia Honda State Park. That being said, parking in places like Old Town can also become a nightmare due to limited space.
Here is one of the most important Key West tips for travelers: if you only plan to stay in Old Town, skip the rental and use bikes or scooters. Otherwise, consider parking outside of town and walking or riding in.

Mistake #3: Overpacking
One of the biggest tourist mistakes in Key West is overpacking. And, on rare occasion, under packing. Don’t bring too much! This is a super casual island. Unless you’re there for a wedding or formal event, you won’t need much.
In fact, keep it casual: you won’t need more than swimwear, flip-flops, a few sundresses or shorts. But don’t forget that sunscreen and sun protection. Include hats, and sunglasses. And reference what to wear in Florida or Key West for reference if you need advice!

Mistake #4: Not Respecting the Sun
Obviously just mentioned, and it might seem obvious since this is literally Florida, but Key West sunburns are no joke. The UV index is often extreme. Tourists underestimate the strength of the sun, especially when it’s breezy.
So, things not to do in Key West: don’t skip sunscreen. Avoid being out and unprotected during peak midday hours. Wear hats. Wear sunglasses. And reapply SPF often!

Mistake #5: Skipping the Sunset at Mallory Square
One of the most iconic Key Wes experiences is the nightly sunset celebration at Mallory Square. Many first-timers skip it or assume it’s overrated (or just the same every night). This is a huge mistake!
A Key West travel tip: arrive early. Grab a mojito! Enjoy the street performers. The incredible sunset view over the Gulf: they’re something you do not want to miss!

Mistake #6: Only Visiting Duval Street
While Duval Street is the heart of the action in Key West, some travelers make the mistake of never exploring beyond it. There’s so much more to Key West! So, consider places to avoid in Key West.
Even on Duval Street, tourist traps overcharge. It’s overpriced for mediocre experiences and food and drinks. Don’t be afraid to venture to the quieter parts of the island, like the Southernmost Point, Fort Zachary Taylor, or local galleries in Bahama Village.

Mistake #7: Eating at Tourist Traps
Speaking of tourist traps and venturing out, many restaurants near Duval Street offer seafood that is just… okay. And it’s expensive! And many locations don’t have stellar service. One of the things to avoid in Key West is assuming all food is good because it’s on the water.
Here’s a Key West tip for travelers: ask locals for recommendations! Look for places like Blue Heaven, Garbo’s Grill, or El Siboney for authentic and delicious meals. And again, go beyond the popular destinations with tourists: your wallet and pallet will thank you.

Mistake #8: Not Checking the Cruise Ship Schedule
Cruise ships bring thousands of tourists into town, meaning they can crowd the streets and nearby popular attractions. If your visit overlaps with cruise ships, it can feel much less relaxing to navigate the crowds, long lines, and just overall businesses.
Make sure to always check and cross check the cruise ship schedule online and plan to do indoor or less-popular activities. Do this especially if multiple shops are scheduled to be docked!

Mistake #9: Ignoring Local Wildlife Guidelines
What not to do in Key West? Interfere with wildlife! It shows respect and decency to read all posted signs and follow the rules. We must preserve the natural environment and remember that we are visiting in their domain!
So, no feeding chickens. No touching coral. No approaching manatees! These are not harmless actions. In fact, many of them are illegal and can cause severe harm to the ecosystem!

Mistake #10: Forgetting Bug Spray
We’ve talked about the sun, yes, but a Key West vacation guide trip: don’t forget the bug spray! You are in a tropical climate. This means mosquitoes. Especially after it rains! If you’re heading to places that feature mangroves in particular, bring the spray.
Of all repellents too, also opt in for DEET-free options! This helps with skin sensitivity. There are also eco-friendly options! Do some research, but don’t leave the hotel without some type of protections. Layers may also help!

Mistake #11: Drinking Too Much, Too Early
First time to Key West? Pace yourself! And hydrate! And definitely don’t mix rum with snorkeling. But in all seriousness, the bars open early in Key West. Combined with their strong cocktails, you can drink too much too fast.
Overindulging in the drinks is not only costly at times (see tip about tourist traps), but it can ruin a day of sightseeing and/or your stomach. This Florida heat is not to be messed with, so drink appropriately, and drink more water if anything!

Mistake #12: Not Taking a Snorkel or Boat Tour
You’re on tropical time with tropical climate! And while we understand some visitors may prefer or stick to land-based activities, we’re saying you’re missing out if you don’t opt in for a snorkel or boat tour. The stunning marine life here is a must see!
So, book a snorkel or a sunset sail. There are plenty of catamaran and eco tours that are worth both your time and money. They will show you a different perspective of the Keys! And it’s a once in a lifetime type of deal to see some of those ecosystems and animals!

Mistake #13: Assuming It’s Just a Party Town
Yes, we know Key West is fun. It has a famous wild side for a reason! But Key West is also home to a variety of other things beyond parties. In fact, it is a literary, historical, and artistic hub. Don’t reduce the island to one thing!
From Ernest Hemingway’s house to the Mel Fisher Maritime Museum, there’s rich culture everywhere. Don’t overlook it! This island is not just bar crawls and t-shirt shops. Take the time and effort to explore beyond the surface.

Mistake #14: Being Disrespectful to the Locals
And no this isn’t just the marine life. Respect goes a long way! The Conchs (the natives of Key West) are long-time residents of the island, and they love their island. They have so much pride in it! So when loud tourists come in, rude behavior doesn’t go unnoticed.
Again, remember you’re in their home. Be polite. Tip Well (this is livelihood!). Support local businesses when you can and just as a general reminder: you’re a guest. When you are kind to others, they’ll be kind for you! And the locals have all the best insight for a fun time!

Mistake #15: Not Budgeting Properly
Key West isn’t a budget destination. You’ll be spending money on food and lodging and tours and transportation! Things will add up quickly, and it’s not uncommon for some first-timers to get caught off guard.
When you consider this, plus tipping, try to use a Key West travel guide to plan ahead. Research your costs, and set a daily budget. But most importantly: follow your budget! This way you don’t have any surprises.
