Highway one is the pacific coastal road from San Fran to LA. It is part of the pan- American highway which starts in Alaska heading south through the Yukon province of Canada, into BC past Whistler to Vancouver (where it is called the Sea to Sky Highway) across the border, into Washington, Orgeon, California and then all the way to Panama and onto Valparaisao in Chile.
It is spectacularly scenic hugging the rugged coastline with crashing surf and remote sandy beaches, interspersed with towering redwoods.
Big Sur was the destination - a selection of high end lodges and eco cabins nestled amongst several national parks stepped in anicent redwoods on the pacific coast ; a calming place with excellent hiking and stunning panoramic views. Great burritos, quiet, and incredible stars as no light pollution. Cabin in woods (+ heated floor + internet for her) + wood fire outside (for him) made for a relaxing few days.
Always good to leave a place wishing you could stay longer. California is cool.
