Train travel is having a moment, and Romania's national railway operator is betting big on it. Starting mid-June, CFR Călători brought back its signature summer schedule of direct international routes, connecting Bucharest to three of southeastern Europe's most magnetic destinations: Bulgaria's port city Varna, Sofia's capital charms, and Istanbul's transcontinental pulse. These aren't your typical daytime hops either. Several routes feature overnight sleeper cars, letting you board in Bucharest and wake up somewhere entirely different.
The appeal here goes beyond novelty. Train travel aligns with what more travelers are actually seeking these days: a slower pace, fewer emissions, and the chance to see the landscape unfold instead of staring at clouds from 35,000 feet. Add in fares that barely crack €60 for international journeys, and you've got something genuinely compelling.
The Istanbul overnight run
The crown jewel is the Bucharest-to-Istanbul service. Depart Bucharest North at 10:46 am, settle into your couchette (four-person compartments available from €57.80 one way), and wake to the call to prayer echoing across the Bosphorus. You'll pull into Istanbul Halkalı station at 9:56 am the next morning, just in time to hit a Turkish breakfast spot before the day gets going. The return journey flips the schedule: trains leave Istanbul at 8:00 pm and arrive in Bucharest by 4:56 pm the following afternoon.
Varna and Sofia for day travelers
If overnight travel isn't your style, the Varna and Sofia routes work perfectly as day trips or short getaways. Bucharest to Varna takes just over nine hours. Trains depart at 10:46 am and arrive at 7:56 pm, giving you time to walk into town and find dinner with a sea breeze. A second-class ticket costs €27. Heading back, you'll leave Varna at 9:30 am and pull into Bucharest at 4:56 pm. Sofia runs slightly longer but still manageable. At 10:46 am departure, you'll arrive at 8:41 pm. Return trains leave Sofia earlier in the morning (7:00 am) and arrive in Bucharest by 4:56 pm. Second-class singles run €33.60.
All three routes maintain daily schedules through mid-October, with the Black Sea route running slightly longer (October 11) than the Turkish and Bulgarian capital services (October 12).
How to book and what to expect
You can purchase tickets up to 90 days ahead through CFR Călători's international booking system, in person at stations across Romania, or online at their international booking page. Physical tickets can be collected at the station or couriered within Romania. Bulgarian-bound travelers can also receive tickets directly on their mobile phones. If you're a European rail pass holder, Interrail tickets work on all three routes.
For travelers eyeing European rail investment more broadly, Europe is quietly rewiring its entire rail network with new tunnels and coastal routes, so services like these are only going to expand. These direct routes represent the kind of sustainable travel infrastructure that's gaining real momentum across the continent.
Why this matters now
These routes hit a sweet spot for summer travelers. You get genuine exploration without the airport queues, accommodation built into your journey if you choose sleepers, and ticket prices that won't wreck a budget. Whether you're hunting for seaside time on the Black Sea, the energy of Istanbul, or Sofia's underrated café culture, you can reach any of these without flying, which matters increasingly to travelers thinking about their impact.
The network runs through October 11 and 12, depending on direction. Pack light, bring a good book or podcast, and let the Balkans roll past your window.
