Don’t get us wrong, we’re all for family vacations. But sometimes there’s something to be said about spending a little good old-fashioned adult time on a tropical island. One of our favorite destinations for a quick grown-up retreat are the beautiful islands of Hawaii. If you’re traveling in child-free mode, you’ll definitely want to look into hotels with adults-only pools. Let’s face it, you know that’s where you’ll post up for most of the trip. Here are five of Hawaii’s best resorts with pools designated for the 18-and-over crowd.

Andaz Maui at Wailea

15-acre beachfront resort Andaz Maui features four cascading infinity pools with a quiet adults-only venue located near the spa. The freshwater Tranquility pool is perfect for watching the Pacific sunset while enjoying morning or afternoon food plates in cabanas. For accommodations, the property has 300 guestrooms and ten luxury residential-style villas.

Four Seasons Hualalai

Located on the Big Island on the Kona-Kohala Coast, the Four Seasons Hualalai has 243 guestrooms, suites, and villas. The adults-only Palm Grove Pool has an infinity edge that makes you feel like you’re actually in the ocean. There’s also a swim-up bar, which serves nature-inspired cocktails and miniature Zen gardens resting on chaise lounge tables.

Grand Wailea

Grand Wailea’s 4,850-square-foot Hibiscus Pool is more than just a pool, it’s an aquatic sanctuary for adults. Inlaid on the bottom is a giant Hibiscus flower made from over six hundred thirty thousand pieces of Mexican glass. Plus, over 2.2 million individual tiles make up the entire pool, which is surrounded by cabanas, lounge chairs, and Jacuzzis.

Grand Hyatt Kauai Resort and Spa

The adults-only pool Grand Hyatt Kauai offers five cabanas in a secluded area to ensure privacy for every guest. Lounge chairs sit around the perimeter and you can typically count on a quiet, serene atmosphere. Many guests even turn their phones off to ensure the area stays tranquil.

Wailea Beach Marriott Resort and Spa

A top feature of Wailea Beach Marriott is the overwater cabanas in the eighteen-plus Maluhia Serenity infinity-edge pool. The infinity-edge offers panoramic views of the Pacific and clients who rent the overwater cabanas enjoy free drinks. Setting the mood is mellow Hawaiian music and warm mood lighting in the evenings.
