question about particles - へも

[wndola]

らいねんのなつ休みはどこへも行きません。

I believe this means: Are you going anywhere for next year's summer vacation?

but I don't really understand the grammatical structure or the use of へも. can anyone take a second to explain?

wndola-san,
へ is marking 'the goal of movement' and も is simply being used for emphasis.
