At Cape Cod - USA (see map), you can take the boat to see the whales.
That was during my summer holidays 2011.
They rarely jump out of the water at that season (I guess) but you can however regularly see their fins, once they come to get some air before going down again and It is impressive and majestuous already.

I liked the reflection of the light on the tail while the water was dripping from it.
