My typical start of the ride through the hills of Malibu :
gas up at PCH and Sunset- happens to be the usual "meet-up" spot for LOTS of riders. From PCH, head north to Las Flores Canyon road.. turn right. Take Las Flores to to Rambla Pacifico where you'll make a right and head up for a short distance then make another right on Schueren take Schueren all the way to the overlook... stop and enjoy the view !.. Then damn near make a u-turn and take Stunt all the way to Mulholland.... Go right on Mulholland.
From Mulholland and Stunt, i'd say head to the Rock Store.... cuz everyone does. Its not always open so check their hours if you want to eat there. Ride "The Snake" which is just a small section of mulholland past the Rock Store.
Take mulholland to Kanan-Dume road.... heres where you have even more choices !
You can continue on Mulholland to some other nice roads...
Or you can turn left on Kanan-Dume road and turn left on... LATIGO CANYON ROAD
Latigo is tight and twisty... Fantastic
I'd say if you follow those directions as a start you certainly won't be disappointed..
You can thank me later
