From Port Denarau, the islands that genuinely work as a day trip sit within about 45 minutes' sailing — Malamala, South Sea Island, Malolo, Mana, Castaway. Push further and the boat time eats the day: the Yasawa options exist but run eight hours or more, and several resorts do not take day visitors at all. Here is which island is which, with the crossings published by the operators.

How long is each crossing from Port Denarau?

Crossing time is the single number that decides whether an island is a day or an overnight. These are the legs each operator publishes.

IslandPublished crossingGroup
Malamala30 minutes (depart 09:30, arrive 10:00)Mamanucas
South Sea Island45 minutes (depart 10:00, arrive 10:45)Mamanucas

Kadavu Lailai / TivuaApprox. 60 minutes each wayMamanucas
Mana, Malolo, CastawayNot separately publishedMamanucas
Mantaray, KuataNot separately published — full-day tripsYasawas

Most operators publish a departure and a return time rather than a sailing duration, which is the more useful figure anyway. Build your day from the published return, not from an estimate.

Which islands can you visit for the day, and what does it cost?

South Sea Cruises operates most of the scheduled day trips out of Port Denarau, and publishes a from-price for each. These are the published headline rates — check the specific product page for the adult and child split.

Ultimate Encounters: Snorkel With Sharksfrom FJ$445IN the Yasawas

The shape of that list is the useful part. A day out at a beach club runs FJ$149–285. A day at a working resort runs FJ$339–369. A day IN the Yasawas runs FJ$399–445 and takes most of your waking hours. You are buying boat time as much as beach.

Cloud 9, moored out IN the Mamanucas, sits alongside these: its own booking platform publishes FJD 249.99 including transfers and a $60 bar tab, or FJD 198 for transfers only, with 9am and 1pm departures from Port Denarau.

Which islands do not take day visitors?

This is the part that saves a wasted enquiry, and almost nobody writes it down.

Likuliku Lagoon Resort publishes that it is "a haven of subtle luxury for adults only and reserved exclusively for guests in-residence at the resort". That is a plain statement: no day trippers. It also publishes that it is "unable to accept guests under 17yrs".

Tokoriki Island Resort publishes itself as "Fiji's most awarded adults-only boutique luxury island resort", with 36 freestanding beachfront villas and a maximum of 72 guests. A resort that small with that positioning is not a day-trip destination, and no day product is published for it.

More broadly: many Mamanuca and Yasawa resorts run excursions — to sandbars, snorkel sites, and to Monuriki — that are open to in-house guests only, priced on the resort's own excursion sheet. If a trip you have read about does not appear on any Denarau operator's schedule, that is usually why.

Do the Yasawas work as a day trip?

They do, on a scheduled product, and you should go in with clear eyes.

South Sea Cruises publishes four Yasawa day options — Mantaray Island Resort, Kuata Island Marine Conservation, the Fiji Island Cultural Experience and the shark snorkel — from FJ$399 to FJ$445. These are real, they run, and the reef IN the Yasawas is better than anything within half an hour of Denarau.

The honest trade-off is the boat day. You will spend a large share of daylight on a vessel, and if you are prone to seasickness or travelling with small children, that is a genuine consideration rather than a footnote. Our standing advice for the Yasawas is to build a rest day around them, or to stay a night rather than day-tripping. If you have three days or fewer in Fiji, the Mamanucas will give you more beach per hour.

What if the schedule does not suit?

Private transfers are the alternative, and they are considerably more expensive.

SeaFiji publishes a private boat transfer service operating "24/7, providing day and night transfers to Resort Destinations in both the Mamanuca Group and Yasawa Group of Islands", from a private jetty at Port Denarau, with rates stated to include Nadi Airport transfers to and from the jetty. It publishes no rate card — only that "Rates are one way fares in Fiji Dollars based on the number of passengers per vessel and include all taxes", inclusive of 15% VAT. Ask for a current rate sheet directly.

SeaFiji's published terms are worth knowing regardless of who you book: one checked bag to 30 kg plus one carry bag to 12 kg, with "Any additional bags, surfboards, or sporting equipment will incur a charge of FJD$25 per piece"; infants 0–1 free with children counted as passengers from age 2; cancellation more than 48 hours out refunded less an FJD$120 service fee, and nothing within 48 hours; and departure times to be reconfirmed 24 hours prior. That last one matters — do not assume a time booked three months ago still stands.

For a sense of what a private crossing costs, Malolo Island Resort publishes its own transfer rates for that route: a private water taxi at F$1,219 one way for up to four people, a shared water taxi at F$912 one way for up to four, and a scheduled seat-in-boat departing Denarau daily at 17:30 for F$256 per adult and F$132 per child one way. Those are Malolo's published figures for its own route, not SeaFiji's, and they should not be applied to other islands.

Choose this way

Two hours is all you want on a boat: Malamala. Thirty minutes each way, FJ$215 for the full day, back at Port Denarau by quarter to five or six.

Travelling with children: South Sea Island. Lunch, drinks, a kids club and a saltwater pool are included, and the crossing is 45 minutes.

You want a real resort, not a day club: Mana, Malolo or Castaway, from FJ$339–369. You get the resort's beach, pools and restaurants for the day.

You want the best water and have the whole day: a Yasawa product from FJ$399. Accept the boat time, and do not stack a 6am activity on either side of it.

You are a group with a fixed programme: a private charter through SeaFiji or a Denarau-based operator, so departure times bend to your run sheet rather than the other way round. Operators are listed at /category/transport and /transport/seafiji.
