I would like to take a northern California vacation with my family in the summer of 2015 (must be summer). It will be me, my wife, and two teenage sons (age 16 and 18). We will fly into San Francisco and include Yosemite in the vacation. We will have 7 days to spend in California. Which would be a better trip? Option A: San Francisco to Lake Tahoe region to Yosemite to Sequoia and back to San Fran or Option B: San Francisco to Big Sur to Yosemite to Sequoia and back. Likely will only spend one full day in San Francisco. We to see the sights. Small hiking. We like adventure and to see beautiful scenery.
