Dhigali Maldives is a private island of the Raa atoll, Maldives. The west end has a comfortable beach with a pool and with picturesque palms, while relatively wild coast with a sandspit can be found in the east. Coastal snorkeling is pretty nice, but you'll have to take ocean tours to see extra large species. Shore and seabed: sand. 
Dhigali Maldives is a 5 star resort (opened in 2017) with rooms' rates starting from US$400 per night. However, more realistic fares are about US$500-700. Unfortunately, the service is not a true Maldivian five stars, and you can find a better hotel for that money.
