Vindoux, South Africa
Set on a family-run farm in the Western Cape, Vindoux's treehouses and cottages offer idyllic views of orchards, vineyards and the Saronsberg Mountains. The stilted houses feature rustic-chic furnishings – four-posters, fine linen and picture windows, as well as spa baths and balconies. A treetop restaurant serves grilled meats and salads, and there's a bush-top pub. After exploring neighbouring wineries or hiking trails, guests can relax in the pool or spa.
Orion, France
In a forested valley overlooking the medieval village of St-Paul-de-Vence, each of these four chic, cedar-wood lodges is named after a Jungle Book character. Veiled by pines and oaks, they come with balconies and grown-up interiors: wooden bathtubs, snowy linen, tactile textiles and broadband. Outside there's a naturally purified pool, boules and a trampoline; the Côte d'Azur is a short drive away.
The Canopy, Australia
Set on a riverbank in the rainforest of the Cairns Highlands, these houses come with a balcony, barbecue and hammock, so you can spy on the neighbours: tree kangaroos, possums and king parrots. Houses sleep between two and six, and have spa baths.
Tree House Lodge, Costa Rica
This lodge is in a wildlife refuge on Costa Rica's southern-Caribbean coast, and comprises beach house, beach suite and tree house. The last is built around a 100-year-old sangrillo tree. Walkways twist between the foliage, where monkeys, sloths and racoons are often visible.
Kinlochlaich Treehouse, Scotland
Built around an oak tree, this octagonal cottage is more Hobbit than Ewok. It overlooks the Appin Hills, with a deck for summer days. Double bedroom, sitting room and bathroom radiate from the trunk, and a spiral staircase leads to a gallery where extra beds can be set up for children. The treehouse is in the grounds of the 18th-century Kinlochlaich House, with woodland walks, fruit and vegetable gardens and tennis courts.
