You know that feeling when a place changes its name but nobody actually listens? That is exactly what happened with Tan-Tar-A Lake of the Ozarks. If you grew up in Missouri or spent your summers trekking down Highway 54, it wasn't just a resort. It was a landmark. A sprawling, cedar-shingled labyrinth of hallways and hidden pools that defined the Lake experience for decades.
In 2017, the corporate world stepped in. Jimmy Buffett’s Margaritaville brand took over, and suddenly the "Tan-Tar-A" signs started coming down. But here is the thing. Locals and long-time vacationers still call it Tan-Tar-A. It's baked into the culture of Osage Beach. People search for it, they book it, and they show up expecting that specific brand of rustic, lakefront nostalgia that the original developer, Burton Duenke, envisioned back in the 60s.
The Identity Crisis of Tan-Tar-A Lake of the Ozarks
Transitions are messy. When the property shifted to Margaritaville Resort Lake of the Ozarks, there was a legitimate worry that the soul of the place would vanish. You can’t just slap a "Fins Up" sticker on a mid-century Ozark icon and expect it to feel the same.
Honestly, the renovation was massive. Millions of dollars poured into the guest rooms to strip away the heavy brown carpets and the 1980s floral drapes. They replaced them with light blues, teals, and "coastal" vibes. It’s objectively nicer now. Cleaner. But for those of us who remember the original Tan-Tar-A Lake of the Ozarks, there’s a strange juxtaposition between the tropical aesthetic and the very Missouri landscape of limestone bluffs and oak trees.
Why does the old name still matter? Because Tan-Tar-A represents the era of the "mega-resort." It was built to be a self-contained city. You didn't have to leave the property to find a bowling alley, an ice rink (which is now gone, replaced by more modern amenities), or multiple swimming pools. That "everything under one roof" philosophy is still the backbone of the resort today, even if the soundtrack has shifted from classic rock to Caribbean escapism.
What’s Actually Different Now?
If you haven’t been since the rebrand, the physical layout remains as confusing as ever. Navigating the "Windgate" or "Oaks" buildings still feels like you need a compass and a prayer.

The biggest change is the atmosphere.
- Timber Falls Indoor Waterpark: This is still the crown jewel for families. It stayed, thankfully. It’s 600 feet of slides and a massive tipping bucket. It’s loud, it’s humid, and it’s the primary reason parents choose this spot during the chilly Missouri winters.
- The Food Scene: Gone are the days of generic buffet lines. Now you have LandShark Bar & Grill right on the water. It’s a massive upgrade in terms of views. Sitting on that deck with a burger while the boats zip by? That’s the peak Lake of the Ozarks experience.
- The Golf: The Oaks course remains one of the most challenging tracks in the state. It didn't need a Jimmy Buffett makeover to be great. It’s world-class, designed by Bruce Devlin and Robert von Hagge. The tight fairways and hilly terrain are purely Ozark.
The "Secret" Spots You Probably Missed
Everyone knows the main lobby and the waterpark. But Tan-Tar-A Lake of the Ozarks—or Margaritaville, if we're being official—has these weird little corners that most people walk right past.
Down by the marina, there’s a sense of scale you don't get from the parking lot. This is one of the largest full-service marinas in the region. You can rent a tritoon, sure, but just walking the docks gives you a real look at the massive cruisers that call this part of the lake home.
Then there’s the horse riding. People forget about the stables. It’s one of the few places left at the Lake where you can take a guided trail ride through the woods. It feels like a throwback to the 1970s resort culture. It’s quiet. It’s dusty. It smells like cedar and horses, which is a sharp contrast to the coconut-scented lotion up at the pool.
Dealing With the Crowds
Let’s be real. This place gets packed. During a holiday weekend, the lobby feels like a subway station.

If you want the best experience, you have to time it. Tuesdays and Wednesdays in late September are the sweet spot. The water is still warm enough for the lake, the outdoor pools aren't a sea of screaming toddlers, and you can actually get a table at JB’s Boathouse without a two-hour wait.
The "off-season" at the Lake of the Ozarks is a bit of a myth now. With the indoor waterpark, the resort stays busy year-round. But there is a distinct shift in October. The bluffs turn orange and red, the humidity finally breaks, and the resort feels more like a mountain lodge than a tropical getaway. This is when the old Tan-Tar-A Lake of the Ozarks spirit really shines through.
Is it Still Worth the Price?
Rates here fluctuate wildly. You might find a room for $140 on a random Tuesday in November, but expect to pay triple that during the Shootout or Fourth of July.
You’re paying for the amenities. If you’re just looking for a bed, stay at a budget motel in Camdenton. You stay here because you want to park your car and not touch it for three days. You want your kids to be able to run from the arcade to the pool while you grab a drink at the tiki bar.
There are criticisms, obviously. Some of the older wings still feel a bit "tired" despite the paint jobs. The sheer size of the property means a lot of walking. If you have mobility issues, this place can be a nightmare without a golf cart shuttle.

The Evolution of Osage Beach Tourism
The story of this resort is really the story of the Lake of the Ozarks itself. It started as a rugged, remote getaway for St. Louis and Kansas City residents. It grew into a massive, commercialized hub. Now, it’s entering a "luxury-lite" phase where branding and experience trump everything else.
The shift to Margaritaville wasn't just about changing a name; it was about survival. The independent "mega-resort" is a dying breed. By aligning with a global brand, the property ensured it would keep drawing in travelers from outside the Midwest who recognize the name. But for the people who have been coming here for forty years, the history is in the bones of the building.
They remember the bowling tournaments. They remember the old excursion boat, the Tropic Island, before it was replaced. They remember when the "Tan-Tar-A" sign was the first thing you looked for when you crossed the bridge.
Practical Steps for Your Trip
If you're planning a visit to the property formerly known as Tan-Tar-A Lake of the Ozarks, don't just wing it.
- Download the Map Early: Seriously. The layout is a sprawling mess of interconnected buildings on a hillside. Study the map before you arrive so you aren't wandering the halls with three suitcases and a crying toddler.
- Book the Waterpark Seperately: If you aren't staying on-site, you can still get day passes for Timber Falls, but they limit capacity. If you are staying on-site, check your package—sometimes the waterpark is included, sometimes it isn't. Don't assume.
- Explore the State Park: You are right next to Lake of the Ozarks State Park. It’s the largest in Missouri. If the resort starts feeling too crowded or "corporate," drive five minutes to the Grand Glaize beach or hit the hiking trails. It's a great palate cleanser.
- Check the Event Calendar: The resort hosts massive cheerleading competitions, corporate retreats, and fishing tournaments. If you want a quiet romantic getaway, check the calendar to make sure you aren't booking the same weekend as 500 middle schoolers in sequins.
- Dining Strategy: LandShark is great for the view, but JB's Boathouse has better breakfast options. If you want to save money, bring a cooler. The resort is fine with you having snacks and drinks in your room, which is a lifesaver given the "resort pricing" at the bars.
The name on the sign says Margaritaville, but the soul of the place is still very much the old Tan-Tar-A Lake of the Ozarks. It’s a weird, fun, massive, and slightly confusing piece of Missouri history that managed to modernize without losing its grip on the lake. Whether you're there for the golf, the slides, or just to sit by the water with something cold, it remains the definitive anchor of the Osage Beach experience.
Plan your arrival for mid-afternoon to beat the 4:00 PM check-in rush. Request a room in the buildings closer to the main complex if you want to avoid long uphill walks. If you're bringing a boat, call the marina at least two weeks out to secure a slip, as they fill up faster than the rooms do during peak season. Finally, embrace the kitsch. Whether it's a parrot or a cedar tree, the point is to forget the "real world" for a few days. That’s what this property has been doing for people since 1960, and that’s what it’s still doing today.
