Casa Marina Key West, Curio Collection by Hilton is the island's best beach-first luxury base: a restored 1920 Flagler landmark on the largest private beach in Key West, with 311 renovated rooms, two pools and an easy 10 minute run from the airport. The trade-offs are a resort fee, a walk to Duval's nightlife, and Key West summer heat.

History and beachfront, in that order. Casa Marina is the most historically important hotel on the island and, after a multi-year renovation, one of its freshest. Railroad magnate Henry Flagler conceived it as the grand terminus of his Overseas Railroad and promised Key West a luxury hotel; he died in 1913 before it was finished, and the resort finally opened on New Year's Eve 1920. The architects were Carrere and Hastings, the same firm behind the New York Public Library. President Warren G. Harding visited in 1923, the Navy took it over as officers' quarters in World War II, and the Army ringed it with barbed wire during the 1962 Cuban Missile Crisis. Few hotels in Florida carry a story this deep.
What separates Casa Marina from the boutique guesthouses of Old Town is infrastructure. The renovation refreshed all 311 rooms, reworked the lobby, two pools, dining and the two Atlantic activity piers, and added an oceanfront event lawn that has made the resort one of the island's leading wedding venues, all while preserving the original building's proportions. It is the rare Key West property where you can run a whole day, sunrise swim to sunset cocktail, without leaving the grounds, though most guests still head into town for dinner at least once.
Book it as Casa Marina Key West, Curio Collection by Hilton. That is the brand the resort joined in 2022, and it is the name on the hotel's own website and on Hilton's booking page as of July 2026. You will see some third-party channels list the property under Hilton's higher-tier Waldorf Astoria brand, which has fueled talk of an upgrade, but the primary sources have not made that switch. Until they do, search and reserve under the Curio Collection name to be sure you are looking at the right rates and the correct property, and treat any Waldorf Astoria listing with a little caution.
The 311 rooms, including 63 suites, split between the original 1920 Flagler building and later additions, and the difference matters. The historic building's high-ceilinged rooms carry a sense of proportion the newer wings cannot match, so if character is the priority, ask specifically for the original structure. If the beach is the priority, the beachfront and new patio suites put you steps from the sand with an Atlantic view and command the sunrise the island is known for. For a honeymoon, a beachfront patio suite is the upgrade that justifies itself. For a family, a room in the main building near the pools balances space and convenience, and the two-pool layout keeps children and couples from competing for the same lounger.
Set expectations correctly on the beach. This is the largest private beach in Key West, roughly 1,100 feet of Atlantic frontage with two restored piers to walk out on, which is a genuine distinction on an island where most hotels have little or no sand. But Key West beaches as a category are shallow, calm and occasionally touched by seagrass rather than the powder-white water of the Caribbean. As a swimming and lounging beach it delivers; as a postcard of turquoise surf it does not, and that gap catches first-time visitors off guard.
On location, Casa Marina sits in the quiet Casa Marina district on the Atlantic side, close enough to walk into Old Town but far enough to stay calm. The south end of Duval near the Southernmost Point is about a 15 minute walk; the busy heart of Old Town and Mallory Square is closer to 25 to 30 minutes on foot, or a short bike ride or quick taxi. Bikes are the local shortcut and a shuttle runs at times. The upside is arrival logistics: Key West International Airport is only about a 10 minute drive away, one of the shortest transfers of any hotel on the island.
Dining sits on the beach and in the historic lobby. Dorada is the oceanfront restaurant, the natural spot for a sunrise breakfast or a sunset drink with your feet near the sand. The Canary Room is the lobby bar for a proper cocktail under the 1920 architecture, and Morrison's Market handles morning coffee and grab-and-go. It is a competent in-house lineup rather than a destination food scene, which suits the resort's rhythm: eat breakfast and a casual lunch on property, then use the short hop into town for Key West's stronger dinner options. Note that the two activity piers and pools anchor the daytime far more than the restaurants do.
The drawbacks are worth stating plainly. First, this is a large resort of 311 rooms, so anyone seeking an intimate, adults-only boutique will find it too big. Second, the distance from Duval means you commute for nightlife and most dinners, so guests who want to stumble out of a bar and into bed should book in Old Town instead. Third, the money math: expect a resort fee of around 45 dollars a night plus paid parking, recently about 30 dollars to self-park or 35 for valet, on top of the room rate.
Fourth, the climate calendar. The winter high season from roughly December to April is expensive and busy, while the August to October window carries real hurricane-season risk alongside high heat and humidity, which is why rates drop then. Fifth, cruise-ship crowds swell Old Town on port days, so if you value quiet, the resort's separation from the center becomes a feature rather than a bug. If you want boutique intimacy or a walk-everywhere Old Town base, book elsewhere. If you want the island's best beach infrastructure with a century of history behind it, this is the one.
Casa Marina is our top pick for a beach-first stay, but the right answer depends on what you want. For an Old Town base at the foot of Duval with the island's best sunset pier, Ocean Key Resort & Spa is the counter-argument. For a waterfront resort closer to the harbor action, consider Pier House Resort & Spa, and for a design-led harbor stay, The Marker Key West.

As of July 2026 the hotel operates as Casa Marina Key West, Curio Collection by Hilton, the brand it joined in 2022, and that is the name on the resort's own website and Hilton's booking page. Some third-party channels list it under Hilton's Waldorf Astoria brand, but the primary sources still show Curio Collection, so book and search under that name.
Yes. Casa Marina fronts the largest private beach in Key West, a roughly 1,100-foot stretch of Atlantic sand with two restored activity piers. Key West beaches are calm and shallow rather than Caribbean turquoise, and seagrass washes up at times, so expect a gentle swimming and lounging beach rather than powder-white surf.
The quiet south end of Duval near the Southernmost Point is about a 15 minute walk. The busy heart of Old Town and Mallory Square is closer to 25 to 30 minutes on foot, or a short bike ride or quick taxi. That commute is the trade-off for the resort's calm beachfront setting away from the bar crowds.
Key West International Airport (EYW) is roughly a 10 minute drive from the resort, one of the shortest airport transfers of any hotel on the island. A taxi or rideshare is quick and inexpensive, which makes Casa Marina an easy arrival even on a short trip.
Yes. Expect a resort fee of around 45 dollars a night on top of the room rate, plus paid parking, recently about 30 dollars to self-park or 35 for valet. The fee typically covers Wi-Fi, the town shuttle, pool towels and activities. Factor both into the nightly cost when you compare rates.
Yes. A multi-year renovation refreshed all 311 rooms, including 63 suites and new beachfront patio suites, and reworked the lobby, pools, dining and the two Atlantic activity piers, adding an oceanfront event lawn. The original 1920 Flagler architecture was preserved through the work.
Both. The scale and two-pool layout absorb families and couples without either crowding the other, which is why it works for honeymoons and multi-generational trips alike. Travelers who want a small adults-only boutique, or to walk out of the lobby into Duval's bars, will prefer an Old Town guesthouse.
