Train beats boat: River cruises cost 6000-8000 HUF and take 2 hours each way. HÉV H5 train takes 45 minutes, costs 680 HUF return with day pass.

Route: HÉV H5 from Batthyány tér (M2 red line). Trains every 30 minutes. Buy Budapest + suburbs day pass.

What to see: Tiny artist town with galleries and Serbian Orthodox Church. Main Square has traditional restaurants with reasonable prices.

Perfect timing: Leave 9am, explore until 4pm, back by 5:30pm. No rushing like cruise groups. Train ride through Danube countryside is scenic bonus.
