Depending on the continent, can be easily possible. For a European, for example, if you are put somewhere in Europe, you will be able to have a reasonable climatic knowledge to know what the Med / Scandanavia / the northern European plain (the bit that goes as far as Eurasia). It might well be a different story in South America for example, but even there you will quickly be able to figure out how far the equator is away ect.
To answer the original post, where I'm living (versus where I'm from) it would be fairly impossible. Berlin is built on a marsh with no noticible features bar Wannsee and Müggelsee, with the Spree and Havel too but neither would look anything more than a generic river.
Dublin on the other hand (assuming I could walk/swim across several seas) would be easily to identify from the bay, Wicklow Mountains and Liffey, unmistakable in fact. Getting there might be a different story, but I guess firstly identify from the landscape and sun where I most probably am, then walk westwards til coast, then up or down based on climate, reach britain, travel roughly west north west til i hit another coast, then locate the Snodon mountains, cross to Anglesea and then due west 80 km over the Irish sea to Dublin bay.
