Romantic Treehouse in the Hawaiian Rainforest

A studio treehouse in Volcano village, five minutes from the entrance to Hawai'i Volcanoes National Park — which makes it the most practical base on this list if the park is why you're coming. Eight-foot sliding glass doors and big windows put the rainforest right at the bed; there's a pitched pine ceiling, a proper kitchen, an indoor/outdoor shower, and a top-level lanai for watching the mist move through the trees. The hosts are superhosts with hundreds of stays behind them and it shows in the details. One thing first-timers don't expect: Volcano sits at about 3,700 feet, so nights are cool and damp — pack a fleece, and budget for an after-dark return to the crater to see the glow when Kilauea is active. Hilo's farmers market and waterfalls are about 45 minutes downhill. Two people, one big room, no compromises on comfort.
