Sunny days fairly scream for an afternoon spent in the park. After traversing Prague's crowded cobblestoned streets, nature is probably calling. Luckily you don't have to stray too far to catch a nice fresh breath in one of Prague's many parks.
Around Prague Castle, there are a number of green and hilly spots to explore. The Garden on the Ramparts is located on the south side of the Castle and offers marvelous views down onto to Mala Strana. The Royal Gardens are actually part of the Castle complex (cross the bridge to reach them) and offer beautiful blooming flowers in the warmer months. If you are up for a walk, you can exit Prague Castle and walk across to Petrin Park. There are lovely rose gardens there and great views across the river and back towards the castle.
Down in Mala Strana the Wallenstein Palace and Garden offers a glimpse of history with your brass and Kampa Island is a lovely spot to take a picnic and watch the dogs frolicking on the lawn. If it is beer you seek, the classic Prague beer garden is located in Letna Park; excellent views, free of charge. Over in Vinohrady climb the hill in Riegrovy Sady - you'll get a great view back to the Castle, plus there's a large beer garden, and an excellent children's park (not connected.)
For a little more wild freedom, head to Stromovka Park for city "center" fresh air, or out to the suburbs and Pruhonice to feel like you've really left the city behind. The Botanical Gardens are a lovely place to explore - combining a number of different styles, including a Japanese Garden and vineyard.
