Walk from Lipany to Kouřim and its open air museum

From Prague, take a bus to station "Vitice,Lipany,mohyla" - check for direct buses but you'll probably have to go to Český Brod first. There is a memorial of famous Lipany battle (1434) - read more at http://en.wikipedia.org/wiki/Battle_of_Lipany 

Follow red trail all the way up to Kouřim - it's an easy walk, less than 7 km, through village called Království (= Kingdom) - no idea of whom. There are lot of geocaches around (TFTC serie + some very popular caches in Kouřim). Ideal for winter / early spring (we did it in Dec. 2011).

In Kouřim, you can spend quite some time sightseeing (historical square, fortification (walls), Jewish cemetary...). There is also astronomical middle of Europe! 

If you have time take yellow trail to educational trail (2,5 km) "NS (naučná stezka) Stará Kouřim" - southeast. Map http://mapy.cz/s/6KeK. First interesting stop is "Lechův kámen" (stone) connected with some legends and beautiful panaroma of the town. Second main point of interest is a former hillfort dating back to years around 4800 B.C. with several settlements during the history. I missed this trail unfortunately but some say the yellow mark dissapers at some parts and goes around the sights. Hope you can find it.

But the main attraction is open air museum (skanzen / muzeum lidových staveb) - collection of old buildings fully equipped to show how people used to live in 17th-19th century. Official website is in Czech only http://www.skanzenkourim.cz.To get there, take green trail from Kouřim square (Komenského and Ruská street, it's less than 1 km).

To get back to Prague, take train to Pečky and change to another train to Praha, Masarykovo nádraží. Train station is 1 km west from the centre. Or there are some buses going to Český Brod (there you change to a train). 

Open air museum in Přerov nad Labem and walk along the river

We did this trip in December 2012.

For only 5,5 km walk we did, start at train station Čelákovice-Jiřina (half an hour from Masarykovo nádraží in Prague centre). Follow green mark. Tourist map: http://www.mapy.cz/s/6JRT. Easy and nice walk along the river. To make the hike longer you can start at Brandýs nad Labem (from there to Čelákovice, follow blue mark until Čelákovice).

You can also add 2,5 km from Přerov n. L. and back following yellow mark to "Přerovská hůra" hill http://en.wikipedia.org/wiki/P%C5%99erovsk%C3%A1_h%C5%AFra

The main attraction in Přerov nad Labem is the open air musem where you can see how our ancestors used to live. Website unfortunately in Czech only http://www.polabskemuzeum.cz/prerov-nad-labem/vystavy. There is a very good photogallery ("fotogalerie") to give you an idea. They have different exhibitions and events during the year following seasons and feasts. Opening hours were (April 2013): Tue-Sun, 9-17, closed for winter. Entrance fee adult 70 Kč.

There is a good restaurant "U skanzenu" very close to the museum.

Further, you can have a look at the chateau from outside.

There is also a "Moto & Velo museum" (I didn't visit). May be interesting though! There are 70 bicycles and 60 motorcycles. http://www.motovelomuzeum.cz

To get back to Prague, better check connections in advance. Mostly you'll have to change (mostly take a bus to Čelákovice and change to a train.
