Las Trampas wilderness, Rocky Ridge loop & More, 11 miles, 2600ft elev. gain

We meet at Las Trampas Public Parking or Bollinger staging area. Parking is large but carpool as usual is recommended.
We'll hike 3 miles on land that belong to EBMUD , so it is good to have EBMUD permit ( https://www.ebmud.com/recreation/buy-trail-permit ). My permit will cover only 4 people.
We'll have 2 miles not very steep uphill before lunch and challenged 2 miles uphill after lunch.
Las Trampas has picturesque views of mt Diablo and local hills.
Some trails may be still muddy and slippery, so poles are recommended.
Our route: Elderberry tr -> Ridge view tr -> Devil hole tr ( steep downhill) -> Rocky ridge tr ( we'll check gate with land bank to see if Rampage peak can be reached from there) -> Rocky Ridge tr ( it belongs to EBMUD , we'll have lunch somewhere in the end of this trail) -> Rocky Ridge Loop tr -> Ohlone Temple Rock ( 0.2 miles out and back) -> Rocky Ridge Loop tr -> Cuesta tr -> Rocky Ridge View tr back to cars
Hike's length and elevation gain is based on Alltrails route estimate. Real one can be longer 1-2 miles.
It is good to have >2.5L water, sturdy hiking shoes , layers clothes , and lunch food.
It is not good idea to join the hike if you don't plan to complete full route.
Contact me using private meetup messages in case you have questions.
Attendance limit - 12. I may add extra 4 hikers based on hiking points.
Hikers who cancel after RSVP closed will get 'NO SHOW', unless they provide reasonable excuse.
