Danube cruises · v1 · Chinese / Romanian / English · an Iron Gates–Black Sea decision, not a booking page
Danube Cruise Selector: Routes, Companies and Seasons on the Romanian Leg
6 real itineraries, 3 companies: Viking sleeps in Bucharest＋Budapest hotels (11 days, from $3,799); AmaWaterways sails short and long (8 days / 14 nights, via Giurgiu); CroisiEurope sails two mirrored 12-day routes (Oltenița–Vienna, from €2,292, plus the Black Sea). All fares are starting fares from capture day, 18.09.2026.
Built from the operators' full pages captured 18.09.2026 ＋ AFDJ (sector definition ＋ levels) ＋ the INHGA Danube bulletins. All three operators say itineraries can change — re-check with the company; dollar and euro fares stand side by side, unconverted.
Three sentences first: all six transit the Iron Gates, none reaches the Delta mouths (Tulcea/Sulina are markers only); the Bucharest gateway differs by company (Viking sleeps in town, Ama uses Giurgiu, CroisiEurope uses Oltenița); fares are dated starting fares, not 'the price of the cruise'.
Brochures sell ships; this page sells the decision: 6 real itineraries, 3 companies, months and fares all retrieval-dated. Fares are the starting fares of capture day, and all three operators say itineraries can change — re-check with the company before booking. No June/July here (no dated departures on the captured pages), no heat/crowd claims (no citable source).
One river: the schematic keeps order only
The AFDJ Romanian sector — Baziaș (km 1,075) to the mouth — runs 1,075 km: one stretch of water, cut six ways by three companies. The schematic below keeps upstream–downstream order only, not distances; the two grey stops (Tulcea, Sulina) are served by none of the six — they close the map's eastern edge plus a pointer. No map needed to read on: every port card sits below in sailing order.
Vilshofen
German embarkation port: only the Grand Danube starts here. Upstream, not detailed.

Iron Gates
All six transit: Viking runs a 'scenic Iron Gate sailing' day, Ama an 'Iron Gates and Dacia's legacy' day, CroisiEurope names it in the route string. AFDJ gauges: Orșova (km 954), Drobeta (km 931). No excursion landing — the banks are the show.
Calls: V1, V2, A1, A2, C1, C2
Vidin (Bulgarian bank)
Viking (medieval castle) and Ama (fortress + traditions) call; CroisiEurope's route string skips it. Across the river sits Romanian Calafat — nobody stops, you only see it.
Calls: V1, V2, A1, A2

Giurgiu
Ama's embark/disembark port (one end of Gems, the end of Grand Danube), named in CroisiEurope's route string; absent from the captured Viking page. AFDJ keeps a branch here. Onward transfer to Bucharest is not described on the captured pages — ask the operator.
Calls: A1, A2, C1, C2
Oltenița
Only CroisiEurope uses it: embark/disembark port for both 12-day sailings (canal–Constanța loop first). It is CroisiEurope's Bucharest gateway, not Giurgiu — gateways differ by company, check when choosing.
Calls: C1, C2
Constanța (via canal)
Only CroisiEurope gets there: via the Danube–Black Sea Canal to Constanța (the site calls the canal a colossal work of Romanian and Eastern European communism). Optional visit: Roman mosque (exterior), Orthodox church (interior), Genoese lighthouse, seafront casino (exterior). The only seaside of the six.
Calls: C1, C2
Tulcea (orientation marker)
None of the six reaches Tulcea. Delta boats and permits live on the site's logistics page, birds on the birding page; here only the direction.
None of the six calls
Sulina / Black Sea (orientation marker)
None of the six reaches Sulina. The end of the AFDJ Romanian sector (Baziaș km 1,075 to the mouth), placed here as the map's eastern edge. For the mouths: the Delta logistics page.
None of the six calls
The route axis: three ways to go
Gorge transit (Viking: Bucharest–Budapest, 11 days, hotels in both capitals); Lower-Danube short sailing (Ama Gems: Budapest–Giurgiu, 8 days, the shortest); full transit (CroisiEurope 12 days Oltenița–Vienna ＋ the canal–Constanța leg, Ama Grand Danube 14 nights Vilshofen–Giurgiu). For the gorge: all six. For the seaside: CroisiEurope only (Constanța, via canal). For the Delta mouths: none of the six — see the logistics and birding pages.
Gorge transit: Viking 11 days
Two Bucharest nights, three Budapest nights, 6 days through the Iron Gates. Both directions (V1/V2) mirrored, from $3,799. For: first visit, unhurried, sleeping in capitals.
Lower-Danube short: Ama 8 days
Gems (A1): embark Budapest, disembark Giurgiu, gorge, Vidin, Ruse included, 8 days, the shortest. No fare on the captured pages — port charges only. For: little time, just the southeast stretch.
Full transit: CroisiEurope 12 days / Ama 14 nights
CroisiEurope (C1/C2): mirrored Oltenița–Vienna, from €2,292, the only seaside (Constanța, via canal). Ama Grand Danube (A2): 14 nights Vilshofen–Giurgiu, 15 stops, the longest. For: the whole transit in one go, 12+ days acceptable.
The company axis: three cards
Each card: products, ships (only what the captured pages name), excursion model, fares (dated starting fares), terms. Viking: included plus optional excursions; Ama: 'daily onshore experience options', no fare published on the captured pages; CroisiEurope: everything optional, CLASSIC guided and DISCOVERY active packages.
Viking (Viking River Cruises, US)

From $3,799 (both directions, as listed on the page captured 18.09.2026; about $345/day, this site's arithmetic).
Operator terms: itinerary and shore excursions are subject to change and may vary by departure. · Itineraries here: V1, V2
AmaWaterways (US)
Two products: Gems of Southeast Europe, 8 days Budapest–Giurgiu; Grand Danube, 14 nights Vilshofen–Giurgiu. Both directions have dated departures.

Daily 'onshore experience options' (the site's wording). The reverse direction has dates and ships, but day-by-day detail is published only Budapest→Giurgiu.
The captured page publishes no cruise fare (18.09.2026); what can be written: port charges $323/person in 2026 (included in the fare, per the site), $378 in 2027, $391 in 2028. Single supplement: 50% (suites 100%).

Ships: MS Vivaldi and MS L'Europe, rotating by departure (the table pairs dates with ships). Excursions are all optional, in two packages: CLASSIC (guided, e.g. Belgrade city tour) and DISCOVERY (active: Belgrade by bike, Bratislava hike); Constanța (mosque exterior, Orthodox church, lighthouse, casino exterior) is optional too. The Bucharest-gateway embarkation port is Oltenița, not Giurgiu.
Black Sea→Blue Danube: from €2,292 pp (03.10.2026 Vivaldi) to €3,060 (04.10.2026 L'Europe); Blue Danube→Black Sea: €2,839–€3,279 (8 departures in 2027). The site's footnote: lowest all-inclusive per-person inside-cabin price, excluding supplements, transportation, transfers, fees, taxes and optionals. About €191–€255 / €237–€273 per day (this site's arithmetic, 18.09.2026).
Operator terms: the order of visits can change, times are approximate. The booking form asks for passport numbers (cross-border sailing). · Itineraries here: C1, C2
The season axis: months from tables, water from bulletins
Under each month sit the dated departures from the operator tables: Viking names only the 2026 season (no monthly breakdown); Ama both sailings September–December ＋ March–April; CroisiEurope one sailing in October, the other April–October. June and July have no dated departures on the six captured pages — this page does not invent them. Level example (AFDJ, values of 18.09.2026 03:00, not means): Orșova (km 954) 2,518 cm, Gruia (km 851) −152 cm (below zero). Before booking, check the INHGA Danube diagnosis＋prognosis bulletins and the AFDJ levels page yourself. No heat or crowd claims here (no citable source). The Delta bird season wheel lives on the birding page — one pointer here.

Viking (V1/V2): 2026 season, months not itemised — appears under every month with this note.
The Delta bird season wheel lives on the birding page (three seasons); no detail here.
Water levels: one dated example ＋ the self-check gate
Example (AFDJ levels page, values of 18.09.2026 03:00, not monthly means): Orșova (km 954) 2,518 cm; Gruia (km 851) −152 cm (below gauge zero); Drobeta (km 931) 680 cm. Before booking, check yourself: the INHGA Danube diagnosis＋prognosis bulletins and the AFDJ levels page (links on the method page).
The selector: month first, wish second
Pick a month ＋ what matters most; the page answers with matching itineraries and reasons. It reads fine without touching it: the full six-itinerary comparison table sits below. Two warnings: dollar and euro fares stand side by side in their own currencies, this site converts nothing; pick 'Delta mouths' and you get an honest zero — none of the six goes there, reason and pointer included.
| Company | Itinerary | Days | Ends | Months | Fare (capture day) |
|---|---|---|---|---|---|
| Viking | Passage to Eastern Europe: Bucharest→Budapest | 11 | Opens with two Bucharest hotel nights, ends with three in Budapest | 2026 season (months not itemised on the captured page) | From $3,799 (18.09.2026; about $345/day, this site's arithmetic) |
| Viking | Passage to Eastern Europe: Budapest→Bucharest | 11 | Opens with three Budapest hotel nights, ends with two in Bucharest | 2026 season (months not itemised on the captured page) | From $3,799 (18.09.2026; about $345/day, this site's arithmetic) |
| AmaWaterways | Gems of Southeast Europe: Budapest→Giurgiu | 8 | Embark Budapest, disembark Giurgiu (8 day-cards); the reverse has dates and ships, but day-by-day detail is published only this way | Sep–Dec 2026, Mar 2027 (operator departure table) | No fare on the captured page (18.09.2026); port charges $323/person (2026, included) |
| AmaWaterways | Grand Danube: Vilshofen→Giurgiu | 14 | 14 nights, Vilshofen–Giurgiu (15 stops); the reverse has dates and ships too | Sep–Dec 2026, Mar–Apr 2027 (operator departure table) | No fare on the captured page (18.09.2026); port charges $323/person (2026, included) |
| CroisiEurope | Black Sea–Blue Danube: Oltenița→Vienna | 12 | Embark Oltenița, canal–Constanța loop first, disembark Vienna; 8 countries (the site's wording) | October 2026 (departures in the operator table) | €2,292–€3,060 pp (03/04.10.2026 departures, Vivaldi/L'Europe; about €191–€255/day, this site's arithmetic, 18.09.2026) |
| CroisiEurope | Blue Danube–Black Sea: Vienna→Oltenița | 12 | Embark Vienna, downstream to Oltenița with the canal–Constanța leg; 8 departures (Apr–Oct 2027), Vivaldi and L'Europe rotating | Apr, May, Aug, Sep, Oct 2027 (operator departure table) | €2,839–€3,279 pp (2027 departures; about €237–€273/day, this site's arithmetic, 18.09.2026). The site's footnote: lowest all-inclusive inside-cabin price, excluding supplements, transportation, transfers, fees, taxes and optionals. |
Re-check with the operator before booking: dates, fares and itineraries can change (original clauses on the company cards).
Before you go: what can change
The original clauses sit on the company cards: itineraries, dates and fares can change, visit order too, times are approximate. At low water the itinerary changes — ask the company how before booking. All three cross borders (Serbia ＋ Schengen states): the CroisiEurope booking form asks for passport numbers, so confirm documents with the operator. Romania Schengen visas have their dedicated site page. Read the fare footnote again: CroisiEurope's 'all-inclusive' excludes supplements, transportation, transfers, fees, taxes and optionals; Ama's single supplement is 50% (suites 100%).
Method
- Operators' full pages captured 18.09.2026: Viking both directions with day-by-day (from $3,799); Ama Gems 8 day-cards ＋ 20 dated departures (ship on each), Grand Danube 15 stops ＋ 20 dated departures, port charges $323/person (2026); CroisiEurope both directions with route strings ＋ departure tables (ships, dates, €2,292–€3,279) ＋ the CLASSIC/DISCOVERY model. Ama publishes no fare on the captured pages — the gap stays visible.
- AFDJ: sector definition (Baziaș km 1,075 to the mouth — the source of the 1,075 km hook) ＋ branches ＋ the dated levels example. INHGA: the Danube diagnosis＋prognosis bulletin collection (a self-check gate for readers). The Danube Commission ports map: reference link only.
- Left out, on the record: June/July departures (absent from the captured pages); heat/crowds (no citable source); Viking ship and embarkation port (unnamed); Ama fares (unpublished); cabin-grade comparison (incompatible definitions); Delta-mouth sailings (nonexistent among the six — see the Delta pages); Iron Gates day trips (see the Cazane page).
