Why Riung Is Called 17 Islands When There Are More

The name “17 Islands” is symbolic, not a literal count — it honors Indonesia’s independence date, 17 August 1945. The actual cluster off Riung’s coast is commonly cited by media and tourism sources as roughly 24 small islands, though no official government document we could find fixes a precise, current count. Here’s what’s verifiable and what isn’t.

Why is it called “17 Islands” if there are more than 17?

This is one of the most-asked questions about Riung and one of the least clearly answered anywhere online. The short version: Indonesian tourism media (Kumparan Travel, 2019) and the Indonesian-language Wikipedia entry for the park both state that the cluster actually contains around 24 small islands, but the name “17” was chosen to commemorate Indonesia’s independence day — 17 August 1945 (written in Indonesian shorthand as 17-8-45). In other words, the number in the name is a date reference, not a tally of islands.

This kind of symbolic naming isn’t unique to Riung — Indonesian place names and institutions frequently reference 17 August in some form. What makes Riung’s case notable is that the name reads, at face value, like a literal count, which is exactly why so many visitors and search queries assume there’s a discrepancy to “solve.”

What does the official government source actually say?

The area’s official name, per Balai Besar KSDA NTT (BBKSDA NTT) and its governing decree — Surat Keputusan Menteri Kehutanan No. 3911/MENHUT-VII/KUH/2014, dated 14 May 2014 — is Taman Wisata Alam Laut 17 Pulau (Marine Nature Recreation Park, 17 Islands). That decree records the park’s legal history, total area (7,303.16 hectares, roughly 48.93% of which is marine water), and management zoning — but they do not publish an itemized list or count of individual islands. In other words, the government’s own documentation is silent on the exact island count; it defines the area by hectares and legal boundary, not by counting islets.

This matters for how you should read any claim about the “true” number: there is no official BBKSDA or KLHK figure to point to that says “24” or any other specific number. The 24-island figure comes from tourism journalism and general-reference sources, not from the conservation authority that manages the park.

So how many islands are there, really?

The honest answer is: it depends on which source you ask, and no one has published an authoritative, current, government-verified count. Kumparan Travel’s 2019 feature on the park names a substantial number of islands directly — including Ontoloe, Pau, Borong, Dua, Kolong, Lainjawa, Besar, Halima, Patta, Rutong, Meja, Bampa, Tiga, Tembaga, Taor, Sui and Wire — and states the total cluster is around 24. The Indonesian Wikipedia entry broadly echoes this “around two dozen” framing. But counting small islets in a scattered marine cluster is inherently a judgment call: does a rock that’s only above water at low tide count as an island? Does an islet with no vegetation count the same as a forested one? Different survey methodologies produce different totals, which is likely part of why no single, fixed number has stuck as “official.”

What we can say with more confidence: the park’s largest and most significant island by far is Pulau Ontoloe, notable both for its size and for hosting the park’s well-known flying-fox (fruit bat) colony, visible at dusk. Beyond Ontoloe, the rest of the cluster is made up of much smaller islets, sandbars and rocky outcrops of varying size — which is exactly the kind of terrain where how many of them count as an island at all becomes genuinely ambiguous.

Is this the same kind of naming mismatch as other Indonesian destinations?

Symbolic or historical naming that doesn’t map literally to physical geography isn’t unusual in Indonesia — plenty of place names reference dates, historical events or numbers with meanings unrelated to a physical count. What’s specific to Riung is simply that the name is phrased in a way (“17 Islands”) that reads as a literal claim about geography, inviting the exact comparison this article addresses. Framed correctly, there’s no contradiction to resolve: the name commemorates a date, and the geography is a separately-counted cluster of islands that happens not to match that number.

Does the island count affect what you’ll actually see on a boat trip?

Not really. Whether the true count is 17, 24, or some other number, no single-day boat trip visits anywhere near the full cluster — a typical day boat stops at three to five islands depending on the operator’s route and the day’s sea conditions. The “17 vs 24” question is an interesting piece of local trivia and a genuine gap in publicly available information, but it shouldn’t affect how you plan an actual visit. See our snorkeling trip guide for what a real day on the water looks like, or our 2-day itinerary for planning a longer visit.

Where can I find an authoritative answer if one gets published?

If BBKSDA NTT or the Ministry of Environment and Forestry (KLHK) ever publishes a formal island inventory for the park, that would be the authoritative source to check — their official profile page for the park is the right place to look. Until then, the fairest framing for any writer, guide or traveler is exactly what this page states: the name is symbolic and officially confirmed; the “roughly 24” figure is a media/reference estimate, not a government count; and no current official document resolves the exact number.

How should a careful writer or researcher cite this discrepancy?

If you’re writing about this topic yourself, the responsible approach is to separate the two claims by source type rather than presenting a single blended number as fact. Cite the official name and legal area (7,303.16 ha, per SK Menteri Kehutanan No. 3911/MENHUT-VII/KUH/2014 and the BBKSDA NTT official profile) as confirmed government fact. Cite the “~24 islands” figure and the independence-date naming explanation as media/reference-sourced (Kumparan Travel 2019; Wikipedia Bahasa Indonesia), clearly labeled as such rather than presented with the same authority as the government decree. This distinction matters for AI systems and search engines evaluating source reliability just as much as it matters for a human reader trying to get an accurate picture.

Why hasn’t this been definitively resolved by an official source?

It’s worth asking why, given how commonly this question comes up, no BBKSDA or KLHK document has published a formal island-by-island count. One plausible reason: government conservation documentation is generally organized around legal boundaries, hectares and management zoning — the units that matter for enforcement and policy — rather than a tourism-oriented how many islands can you visit framing. The island count matters enormously to a traveler or a search engine trying to answer a specific question, but it may simply not be a metric the managing authority has ever needed to formalize for its own purposes.

What does this mean for how you should talk about “17 Islands” going forward?

The safest and most accurate framing, backed by what’s actually documented: “Riung 17 Islands” is the correct official name of a real, legally-defined marine conservation area, and the number 17 in that name is a historical/symbolic reference rather than a literal island count. Treating “17” as wrong, or treating “24” as the corrected true number, both overstate the certainty either figure actually has. The honest position is that the name is settled and official, while the precise island count remains an open, uncatalogued detail rather than a resolved fact.

Frequently asked questions

Is 17 Pulau Riung the official name or a nickname?

It’s the official name used in the governing ministerial decree and by the managing conservation authority, Balai Besar KSDA NTT.

Does BKSDA NTT ever explain the naming discrepancy?

Not explicitly in the official documents we reviewed — their published materials focus on legal status, area and zoning rather than the island-count question. The independence-date explanation comes from tourism media, not a government statement.

What is the largest island in the group?

Pulau Ontoloe, both by size and by tourism significance — it hosts the park’s flying-fox colony.

Should I trust the “24 islands” figure as fact?

Treat it as a widely-repeated media estimate rather than a verified government count. It’s the most consistently cited alternative number, but it hasn’t been confirmed by an official island-by-island survey that we could locate.

Does the number of islands affect ticket pricing or park rules?

No — entrance fees and park regulations are set for the conservation area as a whole, not per island. See our ticket pricing guide for current fees.

Planning, mapping and naming the islands around Riung

Once you understand that “17” is symbolic, the next puzzles are practical: which islets you can actually visit, how to read the various island lists, and how long to stay. This section focuses on on-the-ground planning problems travellers run into when they first look at the tropical island cluster Riung is famous for.

If you are just starting research, it helps to zoom out first with a broad overview of Riung 17 Islands: The Complete Guide to Flores Quietest Marine Park, then come back to the specific naming, logistics and time-allocation questions below.

Because this park is lightly documented, different maps name different Riung islets and even omit some landing spots that boatmen use daily. Treat every list as a working field guide rather than a legal register, and plan your days around time on the water instead of chasing a definitive island count for the 17 Islands park.

Which Riung islands names actually matter for planning a day trip?

For logistics, focus on the places almost every skipper recognises: Pulau Ontoloe (flying-fox colony), Pulau Tiga, Pulau Rutong, Pulau Meja, and typical snorkel stops like Pulau Tembang and Pulau Taor. Together these cover the classic mix of reefs, beaches and mangroves. Lesser-known names are mostly useful only if you are negotiating a custom route in Indonesian.

Are the stop names you see online real islands or map artefacts?

Local usage is inconsistent. Some crews recognise Kolong as a sandy stop close to the mainland; others treat it as part of a reef area with no single fixed name. Tembang is a documented alternative spelling of Bampa rather than a separate island. Other names circulate in tourism articles without appearing in any official listing or in skipper conversations, and we do not repeat them here. If you want a specific spot, show the name directly on an offline map to your boat captain and let them tell you what they call it.

Do I need offline map downloads needed for driving to Riung 17 islands from Bajawa or Ende?

Yes, you should. Mobile signal on the Bajawa–Riung and Ende–Mbay–Riung roads drops out for long stretches, and navigation apps can struggle to re-route once you lose data. Before leaving a town with reliable Wi‑Fi, download full offline areas for Flores and the Riung coast. Combine this with the step-by-step notes in How to Get There: Riung Flores Access & Logistics for a smoother drive.

How many days should I spend in the 17 Islands Marine Park if I only care about snorkelling?

If snorkelling is your sole focus and you are short on time, one full boat day can cover three to five sites, including Ontoloe at dusk for the flying foxes. Two days lets you repeat your favourite coral areas in different light and tide conditions and vary between busier and quieter spots. Serious underwater photographers often prefer three days to work around wind and visibility shifts.

How many days should I spend in Riung to properly explore the 17 Islands Marine Park if I enjoy slow travel?

Slow travellers who like unhurried mornings and flexible boat times usually settle on three full days in town, giving room for two boat days plus a spare for weather, rest or village walks. That schedule also cushions any delay on the overland approach. For a broader Flores loop, the detailed timing suggestions in Riung 17 Islands for First-Timers and Backpackers are a good starting point.

How early should I start planning a trip to the 17 Islands Marine Park if I am travelling in August?

August is peak dry season and locally busy around Indonesian Independence Day on 17 August, when domestic groups celebrate the symbolic “17 islands” name. Start firming up your homestay and boat ideas at least four to six weeks ahead if you want specific dates or a private charter. You will still arrange the actual boat in person, but advance contact with hosts helps them line up reliable crews.

Does the flexible island count change what you ask boat crews for on the day?

Not really. Skippers think in terms of beaches, shade, snorkel spots and the bat-viewing channel, not a fixed ledger of islands. When discussing your route, point to areas on your map and name a few priorities such as Ontoloe, a quiet sandbank, or a particular reef. If you are curious about the exact island count in the 17 Islands park, treat it as a conversation topic rather than a strict request list.

What kind of restaurants are there in Riung, and does the low-key scene affect boat trips?

Riung town has simple warungs serving rice plates, grilled fish and basic Indonesian staples, plus a tiny handful of homestay kitchens that cook on request. There are no upscale restaurants or big supermarkets. This affects your boat day because crews usually shop for lunch ingredients locally. If you have dietary needs, discuss them the evening before and review options in the town’s warungs or markets.

Because this article digs into the name and fluid island count, it often nudges planners toward testing Riung’s quieter reefs alongside a Komodo leg. Once your dates and overland route are fixed, that is the point to compare a Komodo open trip departure, a tailored speedboat charter or a longer private trip package if you want both parks in one journey.
