My recommendations for Oakland for 2-3 days
Lake Merritt is great for a walk, you can walk, run, or bike the 3 miles. On a weekend it's usually packed with people who are picnicking or just relaxing. You can also rent a kayak or a paddle boat. Saturdays there's a great farmers market near the lake. The Grand Lake Theater is a historic movie theater, each screen room is elaborately decorated. They do $5 movies on Tuesdays and also all days before 6 pm tickets are $6. Hope this helps.
I post one photo a day of the places where I live and travel to. Most of my photos are taken with a Nikon RX100 III ????????
