Uphill from this intersection a portion of the Railroad Grade has been taken over by Fern Canyon Rd after the Mt Tam railroad closed. A short distance uphill on pavement brings you to the end of Fern Cyn. A bit before the end the Railroad Grade gravel forest road splits off again to the right. The Temalpa Trail that joins here is steep with stairs, not open to biking.
