Depending on how loose the surface is, you may want a little less air in your tires than you use on pavement.

When you need to brake, brake with the rear first, and feather the front brake gently. Losing traction in the front is a likely crash.

Downshifting before you come to a stop will make starting easier, since you don't have as much traction in the rear either.

Have fun! It sounds really pretty.
