From the web site:
"There is a good trail and propane lanterns are provided. If you have flashlights they are always good to bring along. Wear a light jacket. The self guided tour takes about 1/2 hour. You walk about 1/4 mile in and 1/4 mile out. We hope to extend the trail another 1/4 mile in the near future."
