Chris, if you're on foot it's a bit of a hike, although the scenery's better than most urban walks (apart from the Kaunas scarves flooding towards the stadium). Assuming you can find your way to Princes St from St Andrews Sq, just walk right up the length of it and continue on down Shandwick Place & West Maitland St until you get to Haymarket Station. At Haymarket take the left hand fork, which is Dalry Road and which eventually becomes Gorgie Road. Tynecastle sits just off Gorgie Road. It's a good couple of miles at least, but there are a few decent pubs on the way. Alternatively, a 3, 3A, 25 or 33 bus from Princes St will take you right up Gorgie Road. Or, most simple still, take the train instead, get off at Haymarket and walk the last mile (Dalry Road, Gorgie Road etc). One of the better grounds to visit, and the walk back's well worth it if you've just pumped them...
