Day # 2 (30 May) : Started from Linz and cycled to Grien for about 36 Kms. The cycle path was all along Danube river on a dedicated track. We had lunch at Ardgger Markt, ( salad, Garlic Cream soup, Pasta). One attraction in Grein is Greinburg Castle, built between 1488 and 1493. The castle was purchased by Ernest I, Duke of Saxe-Coburg and Gotha in 1823 and is now owned by a family foundation, headed by Andreas, Prince of Saxe-Coburg and Gotha. The ducal family is living here but the castle is also open for visitors.
