I think one of the easiest ways to get on the track is to become affiliated with your local Lotus Ltd. chapter. They should announce their own and sister track days. Sign up, get a helmet, probably a fire extinguisher, do the maintenance required before (the track will have a list of items to check off) and show up.

If you are uncomfortable with the idea of driving on the track, go to the Lotus Driving School. They will let you abuse their cars while you learn how to drive on a track. Highly recommended.
