There’s nothing like a treehouse to reawaken your childlike sense of wonder. Here are five luxe treehouse hotels — all new or recently expanded — where you can bring it all to life.

1. SECRET BAY, DOMINICA

When it opened in 2012, Secret Bay put the tiny, unadulterated island of Dominica on the map with its four sumptuous villas, each one hand-built on a bluff that juts into pristine waters. Its latest addition came online earlier this month: two sprawling duplex villas (from $1,040 a night) perched atop the dense forest canopy. Each has a “hammock sofa” on the deck and a fully equipped kitchen.

2. PLAYA VIVA, JULUCHUCA, MEXICO

Last fall, this little eco-retreat on the Pacific coast of Mexico opened a dramatic, cylindrical treehouse as a sort of experiment. Since then, it’s been selling out months in advance, and another half-dozen are being built. Meanwhile, book the single treehouse (from $445 per night) for unobstructed ocean views, an unrivaled feeling of seclusion and a hammock that’s sunk into a cutout patch of floorboards.

3. ACRE, SAN JOSE DEL CABO, MEXICO

A year ago, Acre was nothing but a buzzy restaurant on a 25-acre farm, tucked deep into the dusty hills outside Cabo San Lucas. Now it is pushing the envelope with the opening of its treehouse hotel, made up of 12 “stick boxes” on stilts (from $200 per night). They’re compact but space-efficient, with queen beds and outdoor showers that are shaded by palm trees.

4. PAPAYA PLAYA, TULUM, MEXICO

This high-design haven with 85 thatched-roof casitas (from $178, book by email) is spawning its most-covetable rooms yet. The hotel’s treehouse, which is opening for the holiday season, is built out of local Zapote and recycled wood in a spherical shape that’s meant to resemble ancient Mayan structures. The bi-level treehouse has Caribbean Sea views and a dedicated meditation room.

5. HOSHINOYA, BALI, INDONESIA

The soon-to-open Hoshinoya resort (rooms from $700) is going over the top, literally, with a series of seven postmodern, open-air “cafes in the sky” that hover over Ubud’s wild vegetation. Below these serene tea rooms lie a sacred network of canals and rice paddies. Rooms here are on ground level, facing a long lap pool.
