No you can't download huge maps for the halo trial. The maps that are on there are all there is. Even if you could, you would have to buy the full version of Halo to make it work.
However there are map conversions of Halo CE Maps and also even the silent Carthographer Map (The island) for Halo Trial. I can give you the download link for the map but not for the others as it isn't very legal, for the other maps. Just to tell you there is the Halo CE Maps Seclusion and also Yoyorast Island and even better, the Halo 2 Maps Coagulation for Halo Trial. But their not legal and I won't give you the link. sorry. There is also a brand new map created by Queen Ann's Revenge which is called Avast,but it isn't really a big map.

Sorry once again as I cannot give you the download links for the other maps as they are illegal. However, you can download other mods (not Maps) from my Mediafire Account: http://www.mediafire.com/phantomgunex758 ;)

halomaps.org is a very safe website. I have a browser scanner and I scan everything I download for viruses and I have never found a virus on anything from halomaps.org.
Try http://www.halomaps.org/ it's dedicated to map making, editing and they even put their maps up for download, a map editor should be on the top downloads list, if not, search it.
you go to recent maps if its not their then its gone sorry.
