"Liptói-havasok" or "Nyugati-Tátra" in Hungarian.
You already have the two links. An additional idea:
Image containing up-to-date avalanche danger information for Tatras and Fatras
With a link possibly pointing to preferably
(Idea from http://www.hory.sk/)
A not too detailed, but useful map of Slovakia (under 'list of maps' you can search for National parks, mountains, reserves and zoom in)
Hello ! Great page. I suggest that, like "Zapadne" in Slovak, and despite the polish part is smaller, you include the translation in Polish "Tatry Zachodnie" !
p.s: I am not Polish ;)
I have updated the page a bit, including links to the newest peaks, and the accomodation section.
I added also some information about the polish side of the Western Tatras.
