Ligatne is a town in Latvia.
From Riga, take a coach from the main bus station to Augsligatne circa 90 mins (on the way to Cesis). A local bus takes you the last 6 Km to Ligatne.
Take the Cesis road (Brivibas iela) out of Riga. Augsligatne is 17 km after Sigulda, and Ligatne is 6 km down a road to the left after Augsligatne.
Everything in Ligatne is basically within walking distance, although you may wish to take a taxi to the ex-soviet bunker at Skalupes (5Km).
