Take marshrutka #119 from Didube station (Line 2 metro terminus) to reach Mtskheta, Georgia's ancient capital and spiritual heart. Cost is 2 GEL one way with 25-40 minute journey depending on traffic. Departures run every 20-30 minutes from 7:00-20:00 daily. Compare this to organized tours charging 50-80 GEL - you're saving 90% doing it independently.

The main attraction is Svetitskhoveli Cathedral, an 11th-century UNESCO World Heritage site with free entry where Georgia's royal crowns were historically stored. The cathedral supposedly houses Christ's robe and is considered the holiest site in Georgia. Jvari Monastery sits dramatically on a hilltop overlooking the town - accessible via 30-minute uphill walk or taxi ride (10-15 GEL). The monastery marks the spot where St. Nino erected the first cross in 327 AD.

Plan 4-5 hours total to properly explore both religious sites and walk through old Mtskheta's cobblestone streets. Final return marshrutka departs around 20:00 but catch the 18:00 departure to avoid being stranded. Bring lunch from Dezerter Bazaar in Tbilisi to keep total daily budget under 15 GEL including transport and food.

Did this exact route multiple times - much better experience than crowded tour buses. You'll interact with Georgian families on the marshrutka and get authentic glimpses of local life outside Tbilisi. The confluence of Mtkvari and Aragvi rivers visible from Jvari was considered sacred in pre-Christian Georgia.
