The Oltářík is a 565 m high, remarkable mountain on the southern edge of the Bohemian Central Highlands. From here, one has a good view over the valley of the Cheb River towards Prague, but also of the surrounding Bohemian Central Highlands.
On the top of the hill there are ruins of the medieval castle Oltářík. It was built by Hussites in the middle of the 15th century, but was used for a maximum of 100 years and then abandoned for unknown reasons (exact date also unknown).
At Televize Seznam you can find a video (5 min) of a hike from Oltářík via Skálka to Košťálov, which - according to them - are the castles with the most beautiful views of the Bohemian Central Highlands. Unfortunately only in Czech language, but the pictures are also beautiful.
