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.

Sweeping views south and east, all the way to SF, and Mt Tam right above behind you to the north. The bench is dedicated to the family who built their house in front of you 60 years ago.
