Flying an instrument approach in reverse may also get you safely to the MSA, especially if it is a straight-in approach to the reciprocal runway you are departing from.
Using the missed approach might be good too - except the missed approach is designed to be flown from overhead the aerodrome from the minimum descent altitude, which by definition won't coincide when you're departing. But still - the direction of the missed approach track will usually suggest fewer obstacles and lower terrain. A good study of the area beforehand is warranted.
The other useful thing might be the DME/GPS arrival chart - at least gives you an indication of how high you need to be to be safe as you climb away from the aerodrome.
My 10 cents' worth, FWIW.
