It's a hot and sticky summer in St. Louis, and you know what the Kool-Aid Man said — you can't just sit inside. Time to find a pool. But not just any pool — we're talking about hotel pools that make you want to dump your luggage and dive headfirst.

St. Louis is full of great places to swim, relax, and pretend you're filming a music video. The city balances old-school charm with swanky modern vibes. So grab your sunscreen, because we're touring the best hotel swimming pools in St. Louis.

1. The Four Seasons Hotel — A Splash of Luxury

First up is the Four Seasons Hotel, because saving the best for last is rude. This place has a stunning outdoor pool that'll make you feel like a parody of perfection. People actually post poolside selfies here without filters, which is basically stunning.

The pool area is surrounded by beautifully landscaped gardens, and the atmosphere screams "I've made it in life." The water is clean, warm, and the cabanas are so comfortable you might never leave. You'll spend more time here than actual sightseeing, and honestly, that's not a bad plan.

2. Queeny Park Hotel — Old-School Cool

If you love a retro vibe, the Queeny Park area hotels offer outdoor pools surrounded by greenery. These spots feel like a scene from an old movie where families laughed more and phones didn't exist yet. It's nostalgic, refreshing, and exactly what your stressed-out soul needs.

The pools here keep that classic resort feel without trying too hard. You'll lounge like it's the 1985 Olympics and you're watching someone else win gold. Bonus fact — Missouri has over 5,000 lakes, so locals really know how to swim.

3. The Westin St. Louis — Rooftop Bliss

Now we head downtown to The Westin St. Louis, where they said "What if a pool had a view?" Whoa. The rooftop pool sits high above the city skyline, giving you a game-of-thrones-level perspective of downtown St. Louis.

The water practically glimmers against the buildings at sunset, and it's unfair how good it looks. Standing at the edge feels like you're floating above a movie set, and your Instagram followers will seriously thank you. This is where you pretend you own real estate you've never even been to.

4. Hampton Inn & Suites — Affordable and Fun

Not everyone can afford a five-star splash tablet hotel, so let's bring it down to earth. Hampton Inn & Suites offers a clean, refreshing indoor pool that won't break your wallet. It's perfect for families who want kids to splash around without paying a fortune.

The pool might not have piano fusion music playing, but it has what matters — clean water and towels. Sometimes the simplest pool is the one you appreciate the most. Plus, the complimentary breakfast will be your fuel for those cannonball attempts.

The atmosphere is relaxed, casual, and free of unnecessary drama. It doesn't try to be anything it's not, and frankly, we respect that kind of confidence. Sometimes you just need a good swim and a nap, and this pool delivers exactly that.
