Probably a train (Pacific Surfliner) to the ARTIC station and rideshare from there. It’s a 2 hour drive so not sure a rideshare would be willing to do that trip at the drop of a hat.
Train schedules are limited so I’d check times and you’ll definitely want to stay overnight, not a day trip I’d want to do by public transport.
I’m sure there’d be a long day bus tour as well but again, I’d prefer to stay overnight.
All the best.
