Driving Highway 1 through Big Sur means hugging sheer cliffs with the Pacific Ocean crashing hundreds of feet below. You get endless redwoods, hidden coves, and the smell of salt air through the rolled-down windows. Going in late September is the secret move because the summer fog finally burns off, the school-year crowds clear out, and you can actually find a campsite without booking a year ahead.
A typical trip runs about $1900 for gas, food, and places to stay along the coast. Spreading that out over a few months can make the upfront sting a lot easier to handle.
Remember that the 0% intro window is a firm deadline, not free money. If you still carry a balance when those 18 months are up, interest charges will kick in on whatever is left over.
