Removed part of the following You can take a train from the main station (Hlavní nádraží) in Prague to Karlštejn. Trains run every hour starting at 6:25 in the morning (6:25, 7:25, 8:25, ...) For groups of 3 or larger the cost for a return ticket is 30kč per person.
Some of the above no longer applies.
I am still not sure how to deal with that correctly on Wikitravel. For example, this article is little strange. Karlštejn is a small city (market-city) with the famous castle of the same name and some heavy tourist industry (over-priced restaurants, pensions, some commercial museums). It is very often targeted by tourists as a daytrip from Prague (by train, or probably more often, as an over-priced organized trip by bus as sold via tourist-agencies operating in Prague tourist trap areas). Svatý Jan pod Skalou is a different place, also interesting, less known, not part of the Karlštejn itself. And there are many other interesting places in the area (Tetín for example). In fact, the area around Karlštějn is a "national park" (not exactly, real "national parks" as defined by law in the Czech republic have higher level of protection, but this is probably not important for Wikitravel, this place is "protected landscape area") Český kras. This area should probably have an article according to the "national park" template, listing all attractions there. like Karlštejn, Svatý Jan, Tetín, Americas... and so on. An article useful for someone hiking in the area.
Now, if such an article is created, should all information about the city of Karlstejn be in that article, or should Karlstejn have its own article (can cities be in parks, in Wikitravel hierrarchy?). An independent article would probably be useful for people wanting to visit Karlstejn only (as many tourists do), without any hiking in the area.
I see three solutions:
There will be a similar problem with many areas in the Czech Republic. There are many important or interesting attractions that are either standing alone in the country or are part of some really small villages or towns (often with no commercial accommodation). And listing them all under some arbitrary larger cities nearby is confusing. Should the "national park" templates be used in such situations? Kyknos 14:13, 4 May 2009 (EDT)
