My wife and I will be staying in Carlsbad but want to take a day trip to Encinitis and maybe Solana Beach in late Sept. We are both seniors and can drive our car but wonder if it'd be easier to just take the train & do a walking tour. In either town we'd be window shopping and have lunch in one & dinner in the other. We will definitely want to see the Spiritual retreat in Encinitis. Train or car is the question. Thank you.
