Riung 17 Islands Marine Park is a cluster of roughly two dozen uninhabited islets off the north coast of Flores, about 70 km from Bajawa. Travelers come for private boat trips, shallow-reef snorkeling and the flying-fox colony of Ontoloe — and most fold it into Day 3 of a Trans-Flores journey.
Riung in Two Minutes
Riung is a small fishing town in Ngada Regency on Flores’ north coast, and the gateway to the 17 Islands Marine Park. It is the quietest marine park in Flores: no crowds, no speedboat fleets — just wooden boats, reefs and sea.
Known locally as Taman Wisata Alam 17 Pulau, the park is everything the busier parks are not. There are no queues at a ranger station and no drone buzz overhead. Wooden boats put out from a village harbour into a bay scattered with green islets and pale reefs, and on most mornings yours will be one of only a handful on the water.
The town itself is worth an hour of your attention: a strip of stilt houses over the water, a working fish market at dawn, and a harbour where the day’s boats are loaded with ice, fruit and snorkeling gear while the fishing fleet comes in. Riung’s community is a long-settled mix of Bugis and Bajo seafaring families alongside highland Ngada people, and the easy coexistence shows in the pace of the place — nobody hurries, and nothing needs them to.
That quiet is not an accident. Riung sits a winding two-and-a-half-hour drive below Bajawa, far from any airport, which filters out everyone unwilling to earn it. For travelers doing Flores properly — west to east, by road, with time — the Riung marine park is the reward in the middle: a sea day between volcano days.
The 17 Islands: What’s Actually There
Despite the name, surveys count 23 to 24 islands and islets — the “17” honors Indonesia’s Independence Day, 17 August 1945. The stops that matter are Rutong, Tiga, Ontoloe and a shifting white sandbar.
A boat day here is built around a handful of proven stops, and your boatman will read the wind before deciding the order. These are the ones worth knowing by name:
| Stop | What’s actually there |
|---|---|
| Rutong | A climbable grass hill with a 360-degree view over the whole archipelago, and a small white beach below for the post-climb swim |
| Pulau Tiga | Coral gardens on the sheltered side — usually the day’s main snorkeling stop |
| Ontoloe | The largest island in the park: mangrove channels, sea eagles and the flying-fox colony |
| The sandbar | A bare white crescent that surfaces at lower tides — the classic lunch-and-swim stop |
| Tembang & the outer islets | Quieter reefs your boatman chooses by the day’s wind and current |
The archipelago has been protected as a marine reserve since the 1980s and formalized as a nature recreation park, which is why the reefs remain in the condition they are: fishing pressure inside the core zones is light, and the islands themselves are uninhabited beyond the odd seasonal fishing shelter. Most islets are ringed by fringing reef on their sheltered sides, with seagrass flats between them where turtles graze.
Names shift a little from boatman to boatman, and the sandbar itself moves with the tides. That looseness is part of the charm: this is a marine park run at village pace, not corporate pace.
Private Boat Trips & Snorkeling
A Riung 17 Islands boat trip is a full-day, private affair: a local wooden boat for your party alone, three to five island stops, snorkeling gear and a grilled-fish lunch on a beach. We arrange the boat, a private guide and everything around it.
There is no scheduled tour circuit in Riung and no ticket-booth queue — every Riung boat tour is effectively a private charter. Boats leave the village harbour mid-morning, work through the islands at an unhurried pace, and return by late afternoon with everyone salt-crusted and content.
The snorkeling is shallow and generous: coral gardens beginning a few meters off the sand, easy entries straight from the boat, and reef fish in a density that has vanished from busier bays. Visibility peaks in the dry season, when the Flores Sea is at its calmest. This is snorkeling for pleasure rather than sport — warm water, short swims, and no currents to fight on the sheltered sides of the islands.
What turns a local boat day into a Flores Luxury day is the layer we add around it. Your boat carries proper silicone masks and fins in your sizes rather than the scratched communal set, deck cushions and shade, a cooler of cold drinks and fresh fruit, and a guide who knows which reef is working that week. The rhythm is unhurried by design: a snorkel before the sun climbs, the Rutong viewpoint while the light is still kind, lunch grilled on the sandbar, and the flying foxes as the finale. Families do well here — the water is calm and shallow enough for children, and the boat is yours, so the day bends to your pace rather than a manifest.
One honest note on Riung diving: there is no dive operation in town, and no tank you would want to trust. Divers should log their dives in Komodo National Park from Labuan Bajo — our Komodo diving guide covers the sites — and treat Riung as the most beautiful surface interval in Flores.
The Flying Fox Colony of Ontoloe
Ontoloe, the park’s largest island, shelters a flying-fox colony in its mangrove channels — the signature sight of Riung. Boats drift the mangrove edge and watch the colony spiral into the sky.
The flying foxes — kalong in Indonesian — roost in their hundreds along Ontoloe’s mangroves. Boatmen cut the engine and drift close; a clap or a called note sends a slow spiral of them overhead, huge and silent, before they settle back into the trees. At dusk the colony rises of its own accord to feed over the mainland, a river of wings against the last light.
Keep a respectful distance: the colony is the park’s most fragile resident, and the best encounters are the quiet ones. The same mangroves hold kingfishers and white-bellied sea eagles, and on lucky days the shallows around Ontoloe turn up green turtles and a passing pod of dolphins.
Getting to Riung
Riung is reached by road only: about 70 km from Bajawa (2.5–3 hours) or roughly 130 km from Ende (3.5–4 hours). There is no airport and no ferry link — a private car with driver is the way in.
| From | Road distance | Driving time | Notes |
|---|---|---|---|
| Bajawa | ±70 km | 2.5–3 hours | The usual approach — a winding descent from the highlands to the coast |
| Ende | ±130 km | 3.5–4 hours | Along the north coast via Mbay |
| Labuan Bajo | ±224 km | A full day | Broken at Ruteng or Bajawa — this is why Riung belongs inside a multi-day route |
The Bajawa road is the one to take if you have the choice. It leaves the cool volcanic highlands, drops through coffee gardens and bamboo forest, and ends among coconut palms at sea level — Flores’ whole climatic range compressed into a single morning. The surface is sealed but narrow and winding for the final stretch, which is exactly why a good driver matters more here than on the main trans-island road.
We position a private car and driver for the whole Flores journey, so Riung arrives as a seamless stage rather than a logistics problem. As a reference for the road component, a private Toyota Innova with driver runs IDR 1.500.000 per day.

Riung on the Trans-Flores Route
Riung’s natural home is Day 3 of the Trans-Flores journey: descend from Bajawa in the morning, spend the day among the islands, and sleep before pushing on toward the crater lakes of Kelimutu. After two days of volcanoes and mountain roads, a barefoot sea day is exactly what the route needs.
On our Labuan Bajo to Maumere journey, Riung is the hinge of the week — the point where the trip trades altitude for salt water, then trades back. You arrive from the Bajawa highlands, swim the afternoon away, and continue toward Ende and the crater lakes the next morning.
Travelers heading the opposite direction, or building a custom Flores overland tour, can slot Riung in just as easily: it asks for a single night and repays it disproportionately. If a proposed route skips the north coast entirely, question it — this is the detour we argue for most often.
Tours & Prices
There are three practical ways to visit Riung, and all of them are private. Choose by how much time Flores gets in your itinerary.
| Format | Duration | Best for |
|---|---|---|
| Riung day trip from Bajawa | 1 day (boat day, return to Bajawa) | Travelers based in the highlands who want the sea without moving hotels |
| Day 3 of the Trans-Flores journey | 1 boat day inside a 6-day route | Most guests — the natural way to see Riung |
| Riung overnight (2D1N) | 2 days | Snorkelers who want the islands at first light, before any other boat is out |
A word on expectations: accommodation in Riung itself is simple — clean local guesthouses rather than boutique hotels. The luxury in a Riung day lives in the logistics: a private boat, a private guide, a car waiting when you step ashore, and boutique stays positioned in Bajawa and Moni on either side. We plan it that way deliberately, and it works.

Frequently Asked Questions
How many islands are actually in the Riung 17 Islands Marine Park?
About two dozen — most surveys count 23 or 24 islands and islets. The name honors Indonesia's Independence Day, 17 August 1945, rather than the real tally. A typical boat day stops at three to five of them: Rutong, Pulau Tiga, Ontoloe and the sandbar are the classics.
Is Riung worth visiting?
Yes — if you value quiet. Riung offers shallow-reef snorkeling, empty beaches and a flying-fox colony without a single crowd, and it breaks the long Trans-Flores drive perfectly. If you have time for only one marine park, Komodo remains the headline act; Riung is the connoisseur's second act.
How do I get to Riung?
By road. Bajawa is the usual base, about 70 km and 2.5–3 hours away; Ende is roughly 130 km and 3.5–4 hours along the north coast. There is no airport or ferry link, so we arrange a private car and driver as part of every Flores journey.
How long is a Riung 17 Islands boat trip?
A full day. Boats leave Riung harbour mid-morning, make three to five island stops for snorkeling, the Rutong viewpoint and the Ontoloe flying foxes, serve a grilled-fish lunch on a beach or sandbar, and return by late afternoon. Every trip we arrange is a private charter for your party alone.
When is the best time to visit Riung?
April to October — the dry season, when the Flores Sea is at its calmest and snorkeling visibility is at its best. Boats still go out on calm mornings in the wetter months, but we route most journeys through Riung inside the dry-season window.
Can you snorkel in Riung — and is there diving?
Snorkeling is the park's main event: shallow coral gardens with easy entries straight off the boat, ideal for mixed groups and first-timers. There is no dive operation in Riung itself, so certified divers should plan their dives in Komodo National Park from Labuan Bajo and treat Riung as a surface day.
Can I visit Riung as a day trip from Labuan Bajo?
Not realistically — it is around 224 km each way, a full day of driving in each direction. Riung works best as Day 3 of a Trans-Flores overland route, or as a day trip from Bajawa. We build it into private itineraries so the drive, boat and lunch are all arranged before you arrive.
