セントルシア・カストリーズのおすすめホテル10選 2026年版 — ユネスコ世界遺産ピトン、ドライブイン火山サルファー・スプリングス、カリブ海No.1ハネムーンの島

Sandals Grande St. Lucian Spa & Beach Resort is the Sandals flagship on Saint Lucia, built across the narrow causeway that links the mainland to Pigeon Island, a national historic landmark. That spit of sand gives the resort a rare trick: white-sand beach on both sides — a calm Caribbean shore for swimming and a wilder Atlantic side for sunrise walks. It is adults-only, couples only, and genuinely all-inclusive: room, all 11 restaurants, premium-brand drinks, scuba for certified divers, and motorized-free watersports are all covered. There are 4 pools, a Red Lane Spa, an oceanfront wedding chapel, and roughly 301 rooms and suites — the higher grades come with a private butler and a plunge pool on the balcony. Rates start near US$615 a night. Real-guest averages land at Agoda 9.0, Booking 8.8 and Tripadvisor 4.5/5, for a combined 9.0/10. Best for honeymooners and anniversary trips that want zero daily bills.

BodyHoliday Saint Lucia is the Caribbean's most established wellness all-inclusive, open since 1988 on Cariblue Beach at the island's northern tip in Cap Estate, about 30 minutes by road from Castries. Its one trick nobody nearby can match: a free spa treatment every single day of your stay, folded into the room price — massage, facial or body wrap, your pick. Add morning and evening yoga, a full gym, watersports (windsurf, kayak, sailing, snorkeling) and every meal across several restaurants, all on one bill. The 155 rooms mostly face the bay, decorated in warm white-and-cream Alhambra-style arches with a wood-chaired balcony for listening to the surf. Guests score it 8.9/10 on Agoda and 8.7 on Booking — ideal for solo travelers and couples who want to recharge on a quiet private cove. From around $530 a night.

Cap Maison Resort & Spa is a small Relais & Châteaux retreat set on the Smugglers Cove cliffs at the far northern tip of St. Lucia, in the upscale Cap Estate neighborhood next to the 18-hole St. Lucia Golf Club. The design is unapologetically Spanish-Caribbean — warm cream walls, terracotta-tiled roofs, a central courtyard fountain and rounded archways that make every room feel like a private Andalusian villa that drifted into the Caribbean. There are just 49 suites and villas, most with a private plunge pool on the terrace and a few with a rooftop terrace you can sleep under the stars on. The headline draw is Cliff Bar (Rock Maison), clinging to the rock face and famous worldwide for its "rocket service" — champagne lowered by rope to beach tables 15 metres below. Add the fine-dining The Cliff at Cap Maison, a standalone spa villa, and a private Anse Sable Beach reached by a cliff elevator. Guest scores: Agoda 9.1, Booking 9.0, Tripadvisor 4.7/5. Rates from around $415 a night. Best for honeymooners and design-and-food travelers who want privacy over an all-inclusive crowd.

Sandals Regency La Toc is the largest adults-only, couples-only resort in Saint Lucia, spread across more than 200 acres of La Toc Bay just west of the capital, Castries. It's the Sandals closest to town — about 10 minutes from downtown and roughly 15 minutes from George F. L. Charles airport (SLU), so you don't burn the first half-day in a transfer van. The image that sticks is the half-moon beach, a curve of white sand running more than half a kilometre between two green hillsides, with a 9-hole golf course climbing the slope behind it that guests play free. Nine dine-around restaurants are folded into the package — Caribbean, Italian, Asian, a steakhouse — plus the biggest beachfront pool on the island. The roughly 212 rooms and suites range from garden views to top-tier Butler Suites that come with a private golf cart and a personal butler. Real guests rate it 8.7 on Agoda and 8.5 on Booking, praising the scale, the beach and the sheer range of things to do. Our composite score: 8.7/10.

Royalton Saint Lucia, An Autograph Collection All-Inclusive Resort is a 5-star Marriott property that opened in 2018 on Smugglers Cove beach at the very northern tip of the island, in the quiet, private-feeling Cap Estate area. The resort runs roughly 455 rooms and suites split into two clear zones: the Royalton family side with a water slide, kids' club and Splash Park, and the adults-only Hideaway (18+) with its own quiet pool and a romantic mood. The all-inclusive rate covers every meal across 9 à la carte restaurants (most need no advance booking), unlimited drinks at 10 bars, Wi-Fi and basic water sports. Step up to a Diamond Club room and you add a personal butler, a separate check-in lobby and a VIP stretch of beach. It suits families and couples who want an easy eat-and-drink trip without paying full-luxury prices. Overall score 8.3/10.

Sandals Halcyon Beach is the smallest and quietest of the three Sandals resorts on Saint Lucia, sitting on roughly 3.5 hectares of beachfront at Choc Bay, just north of the capital, Castries. Its 169 rooms and suites fill low, red-roofed French-Caribbean blocks scattered under leaning coconut palms along a white-sand beach about 1 km long. This is a couples-only (18+), all-inclusive property — food, drinks (premium-label spirits included), watersports and tips are all baked into the rate. The headline perk is Stay at 1, Play at 3: a free shuttle ferries you to dine and play at Sandals Grande St. Lucian and Sandals Regency La Toc, opening up 21 restaurants in total. Rates start around $390 a night, and the 8.8/10 score leans on reviews praising staff who learn your name. The trade-off: some blocks are older than the bigger resorts, and the main pool is modest.

The Landings Resort & Spa is a 5-star villa resort on the far northern tip of St. Lucia, sitting on the Pigeon Island Causeway at the mouth of Rodney Bay — the one resort on the island with its own private yacht marina, with room for around 80 boats. The 76 villa suites run from 1 to 3 bedrooms, and every single one comes with a full kitchen, a separate living room, a laundry, and a wide balcony with its own private jacuzzi, which makes the whole place feel more like a rented holiday villa than a hotel. The draw is three large pools stretched along the beach, the 7-room Soleil Spa, the seafront Beach Club serving Caribbean food, and a location you can walk from straight into Pigeon Island National Landmark. Rates start around US$415 a night and it suits families settling in for 5 to 7 nights or longer. The honest knocks: resort food runs expensive, and island life means a car for almost everything.

Harbor Club Saint Lucia, Curio Collection by Hilton is a 115-room boutique sitting directly on Rodney Bay Marina at the north end of Saint Lucia, about 15 minutes by car from downtown Castries. What sets it apart from the island's beach resorts is the marina view itself — rows of yachts at their berths instead of an open stretch of sand. Every room has a balcony facing either the marina or a pool, and the rooftop carries 4 separate swimming pools plus a pool bar and sunset views over the Caribbean. It opened in 2017 and joined the Curio Collection by Hilton in 2019, with rates from around $195 a night. The nightlife, bars and restaurants of Rodney Bay Village are a 10-minute stroll away, which makes it a fit for couples, business travelers and anyone who wants to be in the thick of the island's northern tourist strip while still earning Hilton points. Overall score: 8.4/10.

Bay Gardens Beach Resort & Spa is a 4-star, 95-room family resort planted directly on Reduit Beach — widely rated the finest beach on St. Lucia, with fine white sand and clear turquoise Caribbean water. The buildings are low-rise pastel blocks scattered through tropical gardens, with a winding main pool (bridges, a small waterfall), a separate shallow kids' pool, and a Kids Klub for ages 3-12. Non-motorized watersports — kayaks, paddleboards, small sailboats, snorkeling — are bundled into the All-Inclusive rate across 4 restaurants and 3 bars. The location is the real draw: you sit dead center in Rodney Bay Village, a 5-minute walk from JQ Rodney Bay Mall and a strip of beachfront restaurants and bars. Rooms start around $155 a night, and the 8.4/10 score reflects guests who keep praising the same two things — the location and the value.

Auberge Seraphine is a small family-owned guesthouse perched on the Vigie ridge above the yacht marina in the centre of Castries, the capital of Saint Lucia. The white-and-mint Caribbean block with a red-tile roof holds 28 rooms, and nearly every one has a private balcony facing the cove — you sit with morning coffee and watch the yachts work in and out of the harbour, with the sun dropping behind the silhouette of Pigeon Island in the evening. A mid-size outdoor pool and a ridge-top restaurant serving Caribbean-Creole food anchor the place after dark. The real selling point, hard to match anywhere else in town, is the location: the in-town George F.L. Charles airport (SLU) is a 5-minute drive, which makes it a favourite of business travellers, pilots and anyone connecting on to nearby islands. Rooms start around $109 a night — the lowest rate on this list. Overall score: 7.8/10, best for budget stays and short trips.
