The first day I would build
Let the sea set the rhythm before adding bigger outings.
- Use Jinsha Bay or the Xiashan seafront for the first easy coastal anchor.
- Plan seafood after the walk, not as a random meal far from the route.
- Save Huguangyan, Techeng Island, or Donghai Island for a clearer weather window.
Zhanjiang usually works better if the first day has a coastal spine. A seafront walk, seafood, and an easy base give the city its identity faster than a long list of unrelated stops.
Huguangyan and the islands are stronger when they are treated as proper outings. If you squeeze them after a full city day, the coast becomes scenery you rushed past rather than the point of the trip.
