Personally I'd just walk. If you're arriving into the main train station, it's only 15 minutes by foot, and maybe 5 minutes longer if you're coming from town (pretty common for those who have nipped over for a pint or two before kick-off!). You can get a taxi for a few euros. Failing that, the Line 2 bus runs past the stadium - the stop is called Mendizorrotza so you shouldn't have any trouble finding it!There is parking at the stadium, but the odds of getting a space really vary from week to week! The best thing to do is get there nice and early to reserve your spot and then maybe go for a drink or a bite to eat while you pass the time!

The stadium is situated in the south of the city centre, less than 2 kilometers far from there. You have a few options to reach the venue. First of all, you can take bus L2 and get off in Mendizorrotza bus stop or bus L4 and get off in Castilla 67. If you decide to come on foot from the city centre, it is not going to take you more than 25 minutes.
