Grassi Canyon
Upper Grassi Canyon is still closed, although there have been rumors and web posting to the contrary, the status has not changed since last fall.
The uppermost section of the Grassi Lakes Trail — specifically from the top of Spray hill to just north of the pictographs — remains closed due to potential rock fall. The main hiking trails from the Day Use Area to the Grassi Lakes remain open. As well, this closure does not affect access to the lakes for hiking or climbing on the lower rock routes. The closure extends from the upper dam down to just above the climbing formation known as the Golf Course.
The following areas are closed to climbing and hiking: The Ghetto, The Rectory, Swamp Buttress, White Imperialist, and Hermit Wall.
The following areas can be accessed from the lower Grassi Parking area: Graceland, Meathooks, Gardeners Wall, and Golf Course.
Until an unambiguous evaluation of the hazard can be made or the hazard is removed or stabilized, the upper canyon will remain closed.
There has been a problem with people taking down signs and yellow tape. Please respect the signs and the closure. Parks will charge people if they go into the closed area or remove signs.
User groups are continuing to work on a solution to this problem.
