Land OwnerJackson Demonstration State Forest
This is a very old trail that was put in by the CCC in the 1930's and leads to the Woodlands state park. For many years it was ignored and became over grown and impassable. It gets its name from the old steam boiler left there by the logging industry. The lower part of the trail used to be a logging rail road track. Now with the work by the Mendocino Coast Cyclist and the cooperation of Cal Fire and Cal State parks the trail is one of the most popular in the area. It is very rideable in both directions.Just recently a a very nice redwood bench was put in next to the boiler.where you can stop for a rest and snack.
