Take your vacation to new heights with these top-booked tree-house hotels

Tree-house hotels are growing in popularity — and we're not surprised. These elevated destinations give vacationers stunning and often unobstructed views of ocean landscapes, local rainforests or even the aurora borealis.

Their designs tend to be more whimsical and playful than your traditional hotel, and many are built from sustainable materials. That, along with the unparalleled sights, makes a stay in a tree-house abode a truly one-of-a-kind experience.

Tree-house vacations have beat out stays in rooms made crafted from gold or ones made out of ice on Hotels.com. The site says that over the past year, it has seen an almost 30% increase in bookings.

So if you're ready for a vacation filled with panoramic, bird's-eye views straight from your balcony or bedroom, we've compiled a shortlist of the top tree-house stays you can book right now on Hotels.com.

Get ready to take your next trip to new heights -- literally.

Tree Hotel in Sweden is every minimalist's dream. This stunning property stands among the trees in Harads, situated about 40 minutes from Boden. Each room is a different architectural creation, with exterior designs ranging from a spaceship to a mirrored cube completely camouflaged in the scenery it's reflecting. Every interior focuses on clean colors, subtle wooden accents and eco-friendly designs. And, of course, with every room you'll get access to a picturesque view of the surrounding landscape. If you head over there between September and April, you might also catch a panoramic view of the northern lights. It will take sleeping under the stars to a whole new level.

Azulik Eco-Resort & Maya Spa, Mexico (starting at $424; hotels.com)

Imagine a stunning tree house that sits right on the edge of the sea. If that sounds like paradise to you, Azulik might just be your next vacation spot. This eco-resort is on a private, adults-only beach for a more secluded relaxation experience. There, you'll stay in one of their spacious tree houses that feature a private deck with an outdoor daybed to soak up the incredible views of the Caribbean Sea.

Another stunning beachside retreat is the Four Seasons Resort in Costa Rica. This luxury hotel is nestled atop a Pacific coast hillside, overlooking two sandy beaches. The resort's Canopy Suites give you the feeling of a tree house, standing on the hillside and offering unbeatable views of the Pacific Ocean below. Those who stay at the resort also get on-site access to four swimming pools, two private beaches, golf courses, and four restaurants. That's on top of the snorkeling, kayaking, hiking, volcano sightseeing and horseback riding the surrounding area provides.

Keemala, Thailand (starting at $495; hotels.com)

Phuket, a Thai island situated in the Andaman Sea, is known for its abundance of lush rainforest and popular beaches. And at Keemala, a tree-house hotel and spa, you can take in those incredible sights from high above. This elevated destination isn't far from many tourist sites — including Kamala Beach, Bangla Road and Phuket FantaSea — but still feels incredibly remote. During a stay in one of Keemala's signature Bird's Nest tree houses, you sleep among trees and vegetation. Villas offer infinity pools for those who want to swim in the rainforest and freestanding bathtubs with unobstructed views of the ocean. We can't think of any better way to unwind.

Japamala Resort, Malaysia (starting at $137; hotels.com)

Tioman Island is a hotspot for nature lovers. This island off the east coast of Malaysia is a nature reserve that's surrounded by pristine beaches. It's home to rainforests as well as beaches famous for corals and sea turtle hatching. Japamala Resort's tree-house rooms are right in the heart of it. The property sits on a private white sand beach where guests can enjoy snorkeling, fishing or diving. And at night, you can relax on your room's terrace and take in the sunset with a locally sourced meal. It's a recipe for an unforgettable trip.

Aqua Wellness Resort, Nicaragua (starting at $216; hotels.com)

Tree-house hotels situated on the ocean have topped Hotels.com's list. It's almost no surprise when you see the options out there, including the Aqua Wellness Resort in Nicaragua. This beachside residence offers vacationers access to a private white sand beach, free daily yoga classes, kayaks and snorkeling gear and a locallysourced restaurant where people can enjoy Nicaraguan delicacies. But the real highlight at Aqua Wellness Resort is the tree-house accommodation, made from sustainable hardwood, that's completely surrounded by rainforest.

Tsala Treetop Lodge, South Africa (starting at $645; hotels.com)

It's situated between two coastal towns, Knysna and Plettenberg Bay, along the Western Cape, making it an ideal place to stay along the journey. Tsala offers stunning forest views from the treetops where you'll be staying. Each villa and suite also features a private outdoor space and small infinity pool for you to relax and unwind after a day of driving and exploring.

It's ideal for those who are looking for an adventurous trip down under.
