If you need inspiration to plan an incredible getaway, look no further. Whether you're solo and seeking adventure, planning a romantic couples trip or traveling with a group of other adults, consider one of these three unforgettable locales for the kid-free trip of a lifetime.

Big Sur, California

From five-star farm-to-table dining to challenging hikes, spa retreats and wineries galore, adults will find no shortage of recharging activities in Big Sur. Fall is the ideal time to visit this seaside central California region thanks to the stunning weather and reduced crowds compared to the summer high season. Natural beauty abounds, with endless coves, rivers, creeks, meadows, beaches and mountains to explore.

At Julia Pfieffer Burns State Park, traverse the short Waterfall Overlook Trail to access McWay Falls, a secluded beach that's one of the most popular Big Sur destinations. This park also features towering redwoods, the chance to glimpse migrating whales and one of the few places in the region with scuba diving access for the truly adventurous in your group.

When it comes to lodging, you'll have your pick of luxury resorts and remote campsites alike. Don't miss dining at Nepenthe, a Big Sur institution since 1949, or the Big Sur Coast Gallery Cafe, where you can browse works by more than 250 local artisans while you await your meal. You'll see why writers from Hunter S. Thompson to Jack Kerouac have been driven to document the laid-back coastal lifestyle of Big Sur.

Alsace, France

Named as one of the best 2019 destinations by Travel + Leisure magazine, Alsace is a mountainous region best known for producing some of the world's most renowned wines. But it's not all about the vino. Dine at Michelin-starred restaurants like Villa Rene Lalique, housed in a five-star hotel with six bespoke suites overlooking the countryside. Stop at just about any local restaurant to taste a tarte flambée, a local specialty that consists of a flatbread topped with crème fraîche, ricotta, thinly-sliced onions and bacon.

Stroll the streets of the quaint small towns and villages of this region, which are resplendent with floral blooms throughout the spring and summer months. Visit Strasbourg for boutique shopping along with restaurants and bars that offer a taste of the local nightlife. On a rainy day, head to Mulhouse to browse a diverse array of museums. Tour a well-preserved relic like the Haut-Koenigsbourg Castle or explore the ruins of countless others.

Costa Rica

If you're planning a winter getaway, it's hard to beat the luxurious ecoresorts, diverse wildlife and adventurous spirit of Costa Rica. Residents live by the slogan pura vida, or pure life, which epitomizes the relaxed, laid-back attitude of this Central American nation. You'll be surrounded by stunning scenery whether you take a death-defying hike up to the Arenal Volcano, go ziplining at the Monte Verde Cloud Forest Preserve or take in the sunset on the white sand beach at Nicoya Peninsula. At La Paz Waterfall Garden, watch the playful spider monkeys and other rainforest creatures in a setting full of orchids and verdant greenery.

Costa Rica is known for its rich coffee and nourishing gallo pinto, or black beans and rice. Sink your teeth into local ceviche, traditional tapas, artisan goat cheese, fresh fruits and veggies, seafood cocktail, and so much more. In the capital city of San José, you can browse more than 200 vendors at the city's largest market, which has been a staple of Costa Rican culture since 1880.
