AboutVíctor Díaz Expertise I live in Madrid,and travel frequently to Valencia. I have also travelled to many places all over spain, if haven't been there i'd try to help anyway providing my knowledge and links.
I enjoy trekking in the mountains, and know pyrinees, Picos de Europa and mountains in the center.
There is no big difference betweeh bus or train from Alicante to Valencia, depends on the hour of the day, the date, etc, probably buses are a bit cheaper, with not a big difference of time to get to Valencia, just 30 minutes.
In Valencia train station is in the center of the city, but both bus and train stations have metro station http://tinyurl.com/5v5l84
