The St Regis is part of the larger Princeville Resort, which also includes a Westin Hotel, a smattering of condos, two golf courses and a ranch where guests can go riding or zip-wiring.
The St Regis Princeville itself has 251 rooms including 51 suites with the premium suites coming with a dedicated butler.
By Hawaiian standards and in terms of scale the hotel does feel quite big, with a big reception, wide corridors, tall windows, high ceilings and distances to travel within the hotel, but somehow it all works a treat.
The rooms are elegantly decorated with works by Hawaiian artists and have decent-sized bathrooms. One word of warning - the lead-in room categories do not have any outside space, which is pretty unusual in the land of the lanai terrace. The upper room categories do have lanais.
There is a big adult pool, and a separate one for children, as well as a few whirlpools and hot tubs and plenty of sunloungers. On the beach there are further cabanas for hire and a busy beach bar. In the evenings the staff can set the cabanas up for a romantic dinner.
In the main complex is a large spa, and several restaurants and bars. Away from Princeville, there are a huge number of activities on offer including spectacular hiking, paddle boarding, kayaking and zip lining, boat and helicopter tours. Kauai is where the film Jurassic Park was filmed, and the surrounding landscape is exactly what you would expect - flat sandy beach, palm trees, and majestic green hills rising from the sea.
Why we love it
All Hawaiian beaches are public, but the beach at the St Regis Princeville is virtually inaccessible from anywhere else, so is pretty much private in all but name.
