Shameless plug but this is one of the places in my book: The Geek Atlas (http://shop.oreilly.com/product/9780596523213.do).

Bletchley Park is great for its own exhibition, plus it has the UK's national museum of computing: https://en.m.wikipedia.org/wiki/The_National_Museum_of_Compu...

There's a fine guidebook called the Geek Atlas, which should be what you're looking for. Bit US centric though: http://shop.oreilly.com/product/9780596523213.do

My book is three years old now, but it's still relevant. The Geek Atlas: http://shop.oreilly.com/product/9780596523213.do

You might like to read my book, The Geek Atlas, which contains many places related to the history of computing.

It's not exactly what you outline, but The Geek Atlas by John Graham-Cumming lists many places that would fit the description "hacker tourism." It's a travel guide... but it's published by O'Reilly!
