Describe a plan for a trip to San Francisco (Bay Area), California. Your plan should include a budget, a timeline, and a description of the sights and activities at spot
When you visit San Francisco, CA a few local and a few around SF spots are a must-see. Depending on the timeline you can pick and choose between them. I'll describe a few of my favorites for when my own friends and families visit. 

here is a MUST-SEE list within the San Francisco Bay Area 
- Golden Gate - An engineering marvel and a sight to behold, enjoy time with friends and family overlooking majestic views of nature and city alike. The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the one-mile-wide (1.6 km) strait connecting San Francisco Bay and the Pacific Ocean. 

- Lombard Street – also popular as the zig zag street among tourists, San Francisco is very hilly and the city makes the most of it; Enjoy this one of a kind street in the world where a very zig zag steep street, rustling with flowers and beautiful landscaping in the summer, developed as a tourist must see. There are multiple ways to get there - get on the famous trams/cable car, walk up to it, ride a scooter or one of the buggies famous in SF 

- Alcatraz and Pier 39 - these are absolutely touristy places, folks might enjoy the boat ride and stroll an easy evening on Pier 39. Beware, you will find all the same shops that you will find at Navy Pier in Chicago too. 

- If you get a chance visit the Muir Woods in the north, Half Moon Bay in the peninsula, the 18 mile drive in the south and one of my top favorites Yosemite National Park.
