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.

      Of the Endo, Oh No, Boiler downhill section this is the fastest trail, mid run between switchbacks are some fast and flowy sections you can let it rip. Near the top is a grown over flipped car and at the bottom is the rusty old boiler and sweet bench to take in the trail you just ripped!

      Connects well with endo and oh no. Going down of course. This trail tho you could make work going up, not too steep.

      A Super fun flowy downhill that you can lap easily with the fire road access. Super fun at flowy up top, then the grade mellows out and is a bit pedaly at the end.

      Well worth it!

      We hope you've been enjoying Trailforks!
