This is where many visitors over-schedule. After
Saatchi Gallery, choose one continuation:
Chelsea Physic Garden if you want calm and greenery, or
Victoria and Albert Museum /
Science Museum if you want a stronger museum block. If you're visiting with children, one add-on is usually plenty; if you're solo, one longer museum pairing still works well. One add-on keeps the art feeling fresh; three add-ons turn
Chelsea into a spreadsheet. Keep the route human, then move on.
