Here are Maldives resorts known for private‑island experiences (either they are a private/island‑exclusive property you can hire out, or they occupy their own private island and offer private‑island dining/excursions). I’ve noted the type and how guests typically access them.

1. Four Seasons Private Island at Voavah — exclusive‑use private island (whole‑island buyout; 7 bedrooms, yacht and dedicated crew). Access: seaplane + short boat; tailored for groups and events. (fourseasons.com)

2. Kudadoo Maldives Private Island — small fully private island resort (15 overwater residences; operates as a private‑island luxury retreat and can be booked exclusively). Access: seaplane (Lhaviyani Atoll). (Kudadoo.com)

3. Velaa Private Island — ultra‑luxury private‑island resort (very high privacy, villa butlers, bespoke experiences; small number of villas). Access: seaplane. (vanityfair.com)

4. Soneva Jani / Soneva Fushi (Soneva group) — Soneva Jani spans a lagoon made of several islands (very private villas; Soneva also offers Soneva Secret and bespoke private experiences). Access: seaplane + boat. (en.wikipedia.org)

5. Gili Lankanfushi — resort on its own private island with very private villas and a “Private Reserve” (large over‑water private villa/reserve accessible only by boat). Access: speedboat (~20 min from Malé). (staging.visitmaldives.com)

6. Kudadoo’s sister and buyout options — (several resorts like Hurawalhi/Kudadoo offer full‑island buyouts and private‑island hire for events). Access: seaplane. (Kudadoo.com)

7. Cheval Blanc Randheli — occupies its own island in Noonu Atoll; offers villas with extreme privacy and private‑island dining/excursions. Access: seaplane. (Brand/resort operates on a private island.)

8. One&Only Reethi Rah — large private island resort (the whole island is the resort, with extremely private villa enclaves and private sandbank/castaway picnic options). Access: speedboat from Malé.

9. Joali Maldives — private‑island resort known for Villas and private dining/island hire options; whole island resort with exclusive‑use possibilities. Access: seaplane.

10. Raffles Maldives Meradhoo / COMO Cocoa Island / Anantara Kihavah — each is a resort occupying its own island (offering private villas, private sandbanks and bespoke private‑island excursions). Access: seaplane (COMO/Anantara/Kudadoo depending on atoll) or speedboat.

Notes and tips

• “Private island” can mean different things: some properties are exclusive‑use islands you rent entirely (e.g., Four Seasons Voavah, Kudadoo buyouts), while most high‑end Maldives resorts occupy an entire island for the resort and therefore already offer a lot of privacy and private‑island experiences (private sandbanks, castaway picnics, private villas). Check the resort’s wording if you need full‑island exclusivity. (fourseasons.com)
• Transfers: most private‑island or remote‑atoll resorts use seaplanes (from Malé) or domestic flights + speedboat; some nearer islands use direct speedboat transfers. Transfer type affects travel time and cost—confirm with the resort when booking. (maldives.com)
• If you want absolute exclusivity (rent the entire island), ask resorts about “private‑island buyout / exclusive hire” rates and what’s included (chef, crew, yacht/boat, activities).

If you’d like, I can:

• Narrow this to a budget or travel‑time range (e.g., under 45 minutes from Malé),
• Show only exclusive‑hire islands (true full‑island buyouts),
• Or compare 2–3 options (prices, transfer time, what’s included).
