Carmel is in the Monterey Bay region of California.Carmel-By-The-Sea is a beautiful oceanside town along California's Highway 1, complete with dramatic views, white beaches, friendly locals and great food. A mostly upper-class destination for adults, the town itself is small - you can walk across it in five minutes - but filled to the brim with art galleries,cafes,restaurants and inns. Every evening, visitors gather on the pristine beach to watch colorful sunsets. Temperatures in September are perfect - 70 to 80 degrees F during the day and 50's at night. Bring sweaters and dress in layers for all-day activities. Carmel Valley is the valley formed by the Carmel River, flowing some 20 miles from the Santa Lucia mountains to the Pacific Ocean. The town of Carmel Valley is located 12 miles inland from Highway 1, on Carmel Valley Road. Quite often, when Carmel-By-The-Sea is fogged in, Carmel Valley is sunny and warm. http://wikitravel.org/en/Carmel_(California)
