Lake Toba recorded its first documented seaplane landing in 2025, according to operator Santai Seaplane and its parent, Seaplane Asia: a Cessna Caravan reached Samosir Island’s Marianna Resort dock after positioning from Siborongborong and Medan Kualanamu. No scheduled route has followed. As of September 2026, every Lake Toba seaplane trip is a one-off charter, not a repeat of that demonstration flight.
This page covers the landing itself — the story, the airports involved, and what it does and does not mean for anyone planning a Lake Toba trip. For a step-by-step charter guide with booking process and pricing basis, see Lake Toba Seaplane Flights.
What happened on Lake Toba’s first seaplane landing?
According to Santai Seaplane and its Hong Kong-based parent company Seaplane Asia Group, a Cessna Caravan completed a water landing at the Marianna Resort dock on Samosir Island in 2025. The flight was framed by the operator as a demonstration and positioning exercise rather than a commercial service launch — no fare was published, no booking window opened, and no repeat flight has been documented since.
That single landing matters because it is the only publicly documented instance of a seaplane touching down on Lake Toba. Every other claim about “seaplane access to Toba” circulating online traces back to this one flight.
Which airports positioned the aircraft?
Two airports fed the corridor for the 2025 flight, both named by Santai Seaplane as positioning origins.
| Airport | Code | Position relative to Lake Toba | Role in the 2025 flight |
|---|---|---|---|
| Kualanamu International (Medan) | KNO | The larger, farther gateway of the two | Named by Santai Seaplane as one positioning origin; typical entry point for travelers connecting from Jakarta or overseas |
| Sisingamangaraja XII Airport, Siborongborong (also called Silangit) | DTB | Closest airport to the lake shoreline | Also named as a positioning origin; regional airport serving the North Sumatra highlands |
Which airport a future charter would use depends on where the assigned aircraft is based on the day, not on passenger preference — a pattern typical of Indonesian seaplane charters generally, not specific to Toba.
Where exactly did the seaplane land?
Samosir Island’s Marianna Resort dock is the only publicly documented water-landing point on Lake Toba. According to Santai Seaplane, that is where the Cessna Caravan completed its 2025 touchdown. It was the first documented seaplane landing at Lake Toba specifically, though not the first water landing in Indonesia — earlier documented water landings include Bawah Island’s certified water aerodrome and Amanwana on Moyo Island near Benete.
Any Lake Toba dock beyond Marianna Resort remains unconfirmed. Under the Ministry of Transportation’s water aerodrome regulation, a water area only functions as a water aerodrome once its organiser holds a certificate or registry issued by the Minister (Article 29(1)). A request for a different Samosir dock would need the operator’s own depth, obstacle and permit assessment before any landing could be arranged there — that is not something a booking desk can promise in advance.
Is Lake Toba part of Indonesia’s official water-aerodrome plan?
No. A 2025 systematic study on Indonesian water-aerodrome planning identified eight hub airports for further study, each within a 100 nautical mile planning radius: Ngurah Rai, Komodo, Sultan Hasanuddin, Syukuran Aminuddin Amir, Sam Ratulangi, Sultan Babullah, Pattimura and Dominique Eduard Osok. Lake Toba does not appear on that list.
It is worth being precise about what that list is. It reflects hub airports considered in one 2025 planning exercise — it is not an official government register of approved seaplane landing sites, and its absence from the list does not mean Toba landings are prohibited. It does mean Toba sits outside the current planning framework that governs where new water aerodromes might be formally certified next.
Who operates seaplanes in Indonesia, and where does Santai Seaplane fit?
As of an August 2025 statement from a senior Ministry official, two operators fly seaplanes commercially in Indonesia: Travira Air in NTB and Airfast Indonesia in Kepulauan Riau. Santai Seaplane — the operator behind the Toba demonstration — is a separate entity: PT Santai Seaplane Aviation, a subsidiary of Hong Kong-based Seaplane Asia Ltd, whose group also runs Siam Seaplane in Thailand and Samra Seaplane in Cambodia. Santai bases its Indonesian operations at Banyuwangi Airport (BWX), on the opposite side of the archipelago from Lake Toba.
| Entity | Role | Base |
|---|---|---|
| Travira Air | Commercial seaplane operator named by the Ministry (Aug 2025) | NTB |
| Airfast Indonesia | Commercial seaplane operator named by the Ministry (Aug 2025) | Kepulauan Riau |
| PT Santai Seaplane Aviation (Seaplane Asia Ltd) | Operator of the 2025 Toba demonstration flight | Banyuwangi Airport (BWX) |

What does the landing mean for future Lake Toba seaplane access?
On its own, the 2025 landing proves three things: a Cessna Caravan can reach the Marianna Resort dock, the two named airports can serve as positioning origins, and at least one operator group is willing to fly the route as a one-off charter. It does not prove that a scheduled service is coming, that other docks on Samosir are viable, or that pricing will ever be published as a fixed fare.
No unified national booking desk exists for any Indonesian seaplane operator. Flights are arranged through the operator, the resort, or a broker, case by case. Juara Holding Group runs its Lake Toba desk as an independent coordination service, established 2015, arranging charters through licensed AOC-135 partners. It is not Santai Seaplane, it does not own or fly the aircraft, and it is not affiliated with any named airline or operator.
How does this differ from booking a Lake Toba seaplane charter today?
This page documents the single flight that put Lake Toba on the seaplane map. Anyone ready to actually plan a trip needs the operational side: what to include in an enquiry, how positioning and dock status get checked, how pricing is set without a published fare, and the difference between a seaplane charter and the road-and-ferry route to Samosir. That process — enquiry, positioning check, operator quote, confirmed logistics — is covered step by step on Lake Toba Seaplane Flights, including passenger-weight guidance, dock alternatives, and a mode comparison against road and ferry crossings.
Anyone comparing Lake Toba against the wider national picture — the eight government-designated water-landing locations under study, current operators, and how routes are organized region by region — can start from the national seaplane hub at indonesiaseaplane.com.
Ready to ask about a Lake Toba seaplane trip?
Send dates, passenger count and total weight to the Juara Holding Group desk at WhatsApp 6281139414563 or bd@juaraholding.com. The desk checks aircraft positioning and the Marianna Resort dock’s current status before an operator issues a quote — treat every response as conditional until the operator confirms it, since no scheduled service exists as of September 2026.
Frequently Asked Questions
Is there a scheduled seaplane flight to Lake Toba?
No. As of September 2026, no scheduled seaplane service operates to Lake Toba. According to Santai Seaplane, the only documented flight is its 2025 demonstration landing at Samosir Island’s Marianna Resort dock, flown as a one-off charter positioned from Siborongborong and Medan Kualanamu. Any current Lake Toba seaplane trip is arranged individually as a charter, subject to aircraft positioning and permit confirmation before a date is fixed.
Which airport fed the 2025 Lake Toba landing?
Two airports were named as positioning origins: Kualanamu International (KNO) near Medan, the larger gateway, and Sisingamangaraja XII Airport in Siborongborong, also called Silangit (DTB), which sits closer to the lake. Which one a future charter uses depends on where the assigned aircraft is positioned from on the day.
Was the 2025 landing the first seaplane water landing in Indonesia?
No — it was the first documented seaplane landing at Lake Toba specifically. Other Indonesian water landings were documented earlier, including at Bawah Island’s certified water aerodrome and at Amanwana on Moyo Island near Benete. Lake Toba’s landing is notable for the location, not for being a national first.
Can any dock on Samosir Island receive a seaplane, or only Marianna Resort?
Only the Marianna Resort dock is publicly documented as a confirmed seaplane landing point on Lake Toba. Any other dock would need its own depth, obstacle and permit assessment from the operator before a landing could be arranged there — under the Ministry of Transportation’s water aerodrome regulation, a water area only functions as a water aerodrome once its organiser holds a Ministry-issued certificate or registry.
Is Lake Toba included in Indonesia’s official water-aerodrome plan?
Not currently. A 2025 systematic study on Indonesian water-aerodrome planning named eight hub airports for further study — Ngurah Rai, Komodo, Sultan Hasanuddin, Syukuran Aminuddin Amir, Sam Ratulangi, Sultan Babullah, Pattimura and Dominique Eduard Osok — and Lake Toba is not among them. That list reflects one planning exercise, not an official register of approved sites, so it does not rule Toba out of future consideration.
How is this different from the Lake Toba charter booking guide?
This page covers the 2025 landing itself — what happened, which airports and dock were involved, and what it does or does not confirm. The separate Lake Toba Seaplane Flights guide covers the practical side: what to include in a charter enquiry, how pricing is set without a published fare, and how Lake Toba compares to the road-and-ferry route to Samosir.
