Me personally, yes. But I’m biased and live in the Ventura/SB area. I’ll put it this way, people seem to come from LA to ride up here but people up here do not go to LA to ride, ever. Haha
Santa Monica is likely easier to get to for most people especially if flying to LAX. Also probably easier to get to group rides, bike shops, etc. However, PCH is pretty jacked up still north through Malibu from the fires and the entire area is massively more populated/congested than Ventura→north.
I do a couple 1-ish week long camps a year and will generally have this loose agenda. Depends on how much you want to travel between days. Can easily spend multiple days at each stop. With most days around 1-1.5hr drive. Longest transfer would be up to Monterey but you could stay in SLO and south.
day 1-Ojai- sulphur mountain - sisar (gravel)
Day 2 - ride up coast to SB to Gibraltar or mountain dr. (Road). Can do 75+ miles almost totally flat or hit the climbs
Day 3- Los olivos- fig mountain (big climb mix road/gravel) or around solvang, etc for easier day
Day 4- cayucos or Cambria eroica route through Paso Robles and back (mix road/gravel)
Day 5- Cambria or cayucos up the coast to Big Sur/ragged point (road, flat to rolling)
Day 6- Monterey/carmel/santa Cruz- 17 mile dr., Santa Cruz gravel, aptos, etc.
Also, im not great at forums or whatever so you can definitely email me or message, if that’s a things hah
Hope this helps!
