If you like to get some outdoor/nature, then find some good places to hike.
Otherwise.. South end of Richmond, close by Steveston have some good places too. But you should plan to be there early for the best lighting..! I think morning light there is better than dawn.
Richmond Nature park is ok, but not great.. but it is usually pretty quiet, so you can take your time to relax there.
You can also go to George C. Reifel Bird Sanctuary @ Delta
