17 Islands National Park, more accurately known locally as Taman Wisata Alam Laut 17 Pulau Riung, is a protected marine-island destination reached from Riung on Flores’s north coast, Ngada Regency, East Nusa Tenggara, Indonesia. The mapped gateway address is H2WM+CFM, Riung. Travelers come for small limestone-fringed islands, coral-water snorkeling, pale beaches and the large flying-fox colony of Pulau Ontoloe, all visited by local outrigger boat on day trips from the village.
What to Expect at 17 Islands National Park
Despite the page name, this is not a drive-through terrestrial national park: the experience begins at Riung’s waterfront, where visitors arrange a boat and move between uninhabited islets across the calm Flores Sea. The area is widely called Riung 17 Islands Marine Park, a marine nature-recreation reserve whose island count in local descriptions is more symbolic than a fixed itinerary. A standard day on the water combines a wildlife stop, beach time and snorkeling rather than formal trails, visitor centers or staffed galleries.
Pulau Ontoloe is the defining stop. Its mangroves and trees hold a conspicuous colony of flying foxes; boats approach slowly so passengers can watch the bats hanging overhead and circling above the canopy. Other common stops include Pulau Tiga and Pulau Rutong, where clear shallows, reef fish and sandy landing spots make the park a strong choice for swimming and mask-and-fin snorkeling. Coral condition and visibility vary with weather, currents and anchoring practices, so treat the reef as a no-touch environment and never stand on coral.
- Pulau Ontoloe flying foxes: Watch the large fruit bats from the boat or shoreline without entering the roosting trees.
- Coral snorkeling: Shallow reef stops around the outer islands offer tropical fish, hard coral and bright-water swimming.
- Riung boat journey: The open-water ride from Riung is part of the outing, with views back to Flores’s dry north-coast hills.
- Pulau Tiga beach stop: A small-island break for swimming, packed lunches and sand-between-the-toes downtime.
- Low-development islands: Expect natural coves and basic boat-based exploration, not resort infrastructure or commercial beach clubs.

Visiting Tips, Getting There & Nearby Pairings
Arrange the boat through a Riung accommodation or a licensed local operator the day before, particularly in the dry season when demand is higher. Leave early, ideally around 7–8am, for calmer water and more time at the reef before afternoon wind can build. Confirm exactly what the charter includes: fuel, life jackets, snorkeling mask and fins, drinking water, lunch, landing fees and the number of islands. Bring reef-safe sun protection, a rash guard, cash, dry bags and more water than you expect to need.
Riung is reached overland from Bajawa or by continuing across Flores; there is no train, airport shuttle or scheduled city-bus connection to the islands. The reserve is not step-free: boarding generally involves transferring from a shore landing into a small boat, then wading or stepping onto sand or uneven rock. Wheelchair users and travelers with limited balance should discuss transfer assistance, boat stability and landing conditions with their operator before committing. Pair a marine day with Riung village’s waterfront and fishing harbor; for a broader Flores route, Bajawa’s traditional Ngada villages and the Soa hot-spring area are inland destinations requiring a separate drive rather than a walk.
Frequently Asked Questions
When is 17 Islands National Park open, and when should I go?
The protected waters are listed as open every day, but visits depend on daytime boats, weather and sea state. An early-morning departure from Riung provides the most useful window for wildlife viewing, snorkeling and beach stops before conditions become windier.
Do I need to buy tickets or reserve a boat?
There is no single published online admission tariff for a standard visit. Reserve a local boat in advance through your stay or operator, and ask for the full charter price, inclusions and any reserve fee before departure; sharing a boat can reduce the per-person cost.
How much time should I allow for Riung 17 Islands?
Budget five to seven hours for the usual wildlife, snorkeling and beach circuit, including the ride from Riung. Travelers continuing overland toward Bajawa should keep the rest of the day flexible, as boat return times depend on conditions and group pace.
Is the marine park suitable for children or visitors with mobility needs?
Confident swimmers and older children accompanied by attentive adults can enjoy a private boat day with properly fitted life jackets. It is challenging for wheelchairs and anyone unable to manage a small-boat transfer, wading landings or irregular sandy and rocky shores; there are no guaranteed accessible facilities on the uninhabited islands.
