Zero-cost discovery
Free Things to Do in Sofia
What you can genuinely do in Sofia for zero cost, separate from the broader paid-and-free hub and from landmark priority regardless of cost.
This page has one specific job: what actually costs nothing in Sofia, not a broader activity list and not landmark priority regardless of price.
That means naming the free part of a partly-paid landmark specifically, pointing to free formats this site already covers elsewhere, and adding the genuine free spots that no other page currently owns.
For the broader paid-and-free picture, see Things to Do in Sofia. For landmark priority regardless of cost, see Sofia Sightseeing for First-Time Visitors.

Serdica's Largo and Alexander Nevsky's main hall are free; their paid parts are separate.
Walking tours, Vitosha hiking, and pedestrian zones are free formats this page routes to, not re-explains.
Sofia Day brings free museum entry, but it's one specific date, not a standing policy.
Landmarks
The Free Parts of Sofia's Biggest Landmarks
Serdica's "Largo" zone, viewed from street level and the Serdika metro passage, is free to see daily, with no ticket required. The paid Serdica exhibition is a separate experience; see Serdica for the full page.
Alexander Nevsky Cathedral's main hall is free to enter. Only the crypt, run as the National Gallery for Foreign Art's icon museum, is ticketed.
Formats
Free Formats Already Covered Elsewhere
Free and tip-based walking tours are a real format, covered in full on Sofia Walking Tours. Vitosha hiking itself is free; only lifts and ski passes cost money, a distinction Vitosha Mountain covers. Central pedestrian zones are free to explore on foot, covered on Is Sofia Walkable?.
New free spots
Free Spots This Page Owns
City Garden, beside the National Theatre and adjoining the former Royal Palace (now the National Art Gallery), is Sofia's oldest and most central public garden, free to enter.
Slaveykov Square has a bronze statue of writers Petko and Pencho Slaveykov, father and son, and a long-running open-air book market, free to browse. Sofia University's main building is a neoclassical landmark whose exterior is free to view from the street, though that doesn't extend to the interior.
For a more casual suggestion: Lozenets neighbourhood's hilltop streets offer free city views, though this is a lighter, lower-confidence mention rather than a confirmed named viewpoint.
One date
One Date Worth Knowing
Sofia Day, 17 September, brings free entry to several Sofia Municipality museums, including Sofia History Museum and Sofia City Art Gallery. This is a specific annual date, not a standing weekly or monthly policy, so check whether it lines up with your trip rather than expecting it year-round.

Before you travel
What's Worth Confirming Yourself
Whether the crypt or the Serdica exhibition ticket has changed, and whether Sofia Day's free-entry list still matches this page, are both worth confirming yourself before you rely on them.
