It's a little early and highly variable depending on the snow season. The Horse Lake/Sage Hills trails above Wenatchee are closed until April 1 and maybe longer depending on conditions. Freund Canyon? Maybe. #2 Canyon usually starts riding decently late April. Anything higher will still be under snow. Ask again in March 
Ancient Lakes and some of the trails a little further east should be rideable.
Trails in Kittitas County will be under snow or too muddy.
