Castle Resorts & Hotels officially launched its newest property on Kauai. Known as The ISO, an acronym for Island. Sky. Ocean., the 79-room hotel offers a private, oceanfront retreat on the island’s Royal Coconut Coast.

Formerly known as the Mokihana Resort, the property underwent a $5-million renovation of the lobby, guestrooms, exterior and grounds. The ISO is the only property on Kauai’s east shore that sits on the ocean’s edge without any form of separation. As a result, all of the rooms offer ocean views.

“We’re excited to launch The ISO as Kauai’s newest boutique hotel,” Alan Mattson, president & COO of Castle Resorts & Hotels, said in a statement. “It has always been a gem of a property with its direct oceanfront location, expansive lawn, pool, and one of the island’s most popular restaurants, The Bull Shed, but now it will be even more spectacular.”

Join us at Part 3 of Hotel Optimization – A Virtual Event on January 27 from 10am – 1:05pm ET for expert panels focused on getting you back to profitability.


The guestrooms have a rustic, contemporary décor and include a refrigerator, coffee maker, flat-screen TV, Wi-Fi, Bluetooth, USB capable clock radio, canteen coffee mugs and refillable water bottles. Guests also have access to yoga mats.

Among the property’s amenities are an oceanfront swimming pool, a large grass courtyard with lounge chairs and tiki torches, fire pits and filtered water stations. The ISO is also home to the island’s Bull Shed Restaurant, which specializes in gourmet steaks, prime rib and fresh island seafood.  

Designed for the active traveler, The ISO offers guests yoga and other fitness options on the oceanfront lawn, as well as bikes to explore the area and the four-mile coastal trail. It is also located near hiking trails, golf, waterfalls and gardens and is centrally located 10 minutes from the airport and in close vicinity to the shops and restaurants at the Coconut Marketplace.
