North with Polaris in the shot gives you circular trails around it. South will give you long curved streaks across the sky, plus perhaps a bright-cloudy area of the Milky Way. You can do shorter exposures facing south, & still have good-length trails. Stars closer to Polaris make shorter streaks in the same length exposure.
On 200 film I shot half an hour at f4-ish in both directions. You can extrapolate for your camera or look up some ideas online. Use as wide an angle as you have, with most of the scene being the sky & just a little of the ground at the bottom. Use a flashlight to light the grass & sand & you get a cool foreground -- just shine it around moving slowly over the ground for a few minutes. Make sure you stay behind the camera if you don't want flare.
There are threads on the forum with lots more info, just search "astrophotography". I liked
this book. It's mostly about film though; there are many on digital. I'm just getting started with it, & it's too cold now. Looking forward to spring

It looks like you have a good spot for it too.
