The tree house at Rubondo Island Camp is a getaway from a getaway: a treetop refuge set back from the eight cottages of the main camp, where guests are invited to have a “sleep out” under the stars overlooking Lake Victoria. Spend your day observing wildlife on safari by foot or canoe, and then retreat to your elegant room among the branches to soak al fresco in a copper bathtub, watch the sun set over the lake, and enjoy a romantic evening by lantern light.

Find yourselves enshrouded by thick rain forest in a stunning thatched bungalow set on the banks of the Pacuare River. The Canopy Honeymoon Suite’s wide screened windows provide a 180-degree rain forest view, while the lush trees ensure complete privacy. Follow a private suspension bridge to your suite, elevated above the forest floor, and relax in a hammock on the covered deck or cool off in your own spring-fed stone pool.

Located on its own atoll in French Polynesia, the Brando is the very picture of an idyllic romantic getaway: sugar-sand beaches and warm, aquamarine waters; bowing coconut palm trees; tropical birds and flowers; and the lilting rhythms of the South Pacific. Be each other’s snorkel or dive buddy, go beachcombing together, and indulge yourselves with a couples massage high in a treetop suite.

High above Santorini’s caldera, your honeymoon suite at Kapari Natural Resort is a cozy paradise of white-washed walls and soft geometry, where the view is phenomenal, the balcony breezy and sun-splashed, and the private hot tub sky-lit. Whether you are hikers, archaeology buffs, or just like to wander through age-old villages together to soak up the local flavor, you’ll rise each day to views of the Aegean and end your evenings by the fireside in this spectacular cliff-side cave dwelling.

No matter how you define a romantic experience, you will find it at Petit St. Vincent. You might settle into a hidden nook on an empty stretch of beach and laze there all day, raising a flag whenever you wish a drink or a bite to eat. Or go exploring together, snorkeling, kayaking, or sailing, even picnicking on your own on a deserted sand island. Enjoy a candlelit dinner on your private terrace—or take all your meals there and forget the rest of the world exists.

Rocky outcrops and tropical forests have carved out secluded beaches along the shores of Fregate Island. When you and your mate find the perfect one, flip the “Beach Vacant” sign to “Beach Occupied” and it’s yours for the day. If you’re worried a passing Aldabra tortoise might be a third wheel, go snorkeling together right from the beach or stretch out around your private pool instead. Sip champagne in a serene water garden after a massage, and enjoy meals in a treehouse surrounded by tropical birds, barefoot by candlelight on the beach, or anywhere you wish.

The floodplains of the Okavango are vast and wild, but you seem to have them all to yourself at Zarafa. With only five luxury lagoon-side tents, Zarafa Camp is a delightfully intimate corner of one of Africa’s great wilderness areas. Watch for wildlife together from your private veranda, enjoy cocktails while boating past hippos on the lagoon, and—for National Geographic guests only—sit down to an excellent private meal in the bush followed by a special viewing of a National Geographic wildlife film shot right here.

Set just above a secluded cove called Lovers Bay, and just below two sudden, vertical mountains, Capella Lodge strikes a balance between intimate serenity and breathtaking drama. The tiny island of Lord Howe welcomes only 400 visitors at a time, but the other 398 seem far away at Capella. Take bikes or kayaks out to explore together, admire the view from daybeds on your private deck, and enjoy sunset drinks and appetizers on the beach at Lovers Bay—an exclusive for National Geographic guests.

Wake up in your canopy bed in Ashford Castle and you may have to remind yourself that you are not royalty and it is the 21st century, not the 16th. The castle is so full of history, so beautifully appointed with period antiques and textiles, that a stay within its 800-year-old walls is the very definition of romantic. Go for a horseback ride or a hike along stunning Lough Corrib, challenge each other to a game in the stately Billiards Room, or sneak down to centuries-old secret passageways for a tasting of fine wines.

Each thatched cottage at andBeyond Benguerra Island occupies a slice of tropical paradise, providing visiting pairs with their own sandy haven, outfitted with a private veranda, saltwater plunge pool, and cabana that shades a swinging daybed. Spend your days playing on the beach or in the water, and then sail—or gallop—into the sunset on sailing and horseback riding excursions. Come mealtime, request a table for two, set up just for you at the water’s edge, or have a couple’s castaway picnic delivered to a remote sand shoal jutting into the turquoise shallows.
