A/B retain their researched northern/central itinerary. Southern C researched 25 October 2026. Entry sources: Slovak ministry, Vietnam government exemption list, official pre-arrival portal and official e-visa site. The existing researched Slovak tourist-exemption assumption covers 15 August 2025–14 August 2028, subject to conditions. Recheck eligibility and Hanoi arrival-form instructions before travel. Passport guidance follows the stricter Slovak advice of six months after departure.
Destination and transport sources: official climate guide, Ninh Binh, Sa Pa, sleeper operator FAQ, official railway booking, Sun World 2026 tickets, UNESCO Hue, Hue climate/transport, Hanoi–Hue airline route, Hue–Da Nang rail corridor and example driver. A/B include Sa Pa, Hue and Ba Na Hills; C uses Cat Tien and Da Lat. Exact flight, room, train and activity inventory remains unconfirmed.
Health: CDC Vietnam. Roads: German Foreign Office. Payments: N26 abroad. Sources provide context and do not validate all model prices. EUR amounts are planning allowances, not live November offers; no current exchange rate is claimed. Reconfirm tariffs, packages, dates and availability before paying.
Hoi An remains an optional replacement idea: UNESCO Ancient Town, heritage lantern guide, example workshop and municipal village visits. Monthly November lantern-night dates remain unverified; the December festival is outside this trip.
Original photographs retain their individual source, credit and licence metadata. Photos may show another season or expressly captioned wider-area/station illustrations. Stay pins are suggested areas, not selected hotels; train-night pins are boarding stations. Lines and local loops are schematic, not navigable roads, railways, trails or boat routes. Online map resources and external links require internet. Nothing is booked.
Southern option sources, checked 25 October 2026: Vietnam Tourism Da Lat, Cat Tien National Park, older park route / service reference, EAST Dao Tien and transfer guidance, Tuyen Lam destination page and Vietnam Airlines August reopening. Reopening establishes a corridor, not a confirmed flight on 26 November. Source photographs keep individual credits and licences; none promises future weather or animal sightings.
