Getting there & away
There are frequent local trains from Dresden to Schöna (€5.20, 1¼ hour, every half hour), on the German (west) bank of the river opposite Hřensko. From the station, a ferry crosses to Hřensko (€0.85 or 12Kč, three minutes) on demand.
From Prague, take a bus (84Kč, 1¾ hours, five daily) to Děčín, then another to Hřensko (14Kč, 20 minutes, four daily). Alternatively, catch a Dresden-bound train and get off at Bad Schandau (184Kč, two hours, eight daily), then a local train back to Schöna (€1.80, 12 minutes, every half hour).
On weekdays there are three buses a day (year-round) between Hřensko and Mezní Louka (8Kč, 10 minutes), and two a day at weekends (July to September only).
