San Diego Airport Layover: Terminals and Bay

San Diego International Airport sits on the north shore of the bay three miles from downtown, and a connection too short to leave it still buys you Sunset Cove, the food hall behind security in Terminal 2, or the bayfront path at Spanish Landing Park a short walk beyond the terminal doors.

Sunset Cove, the food hall under Terminal 2’s window wall

Sunset Cove is a room rather than a corridor of counters: a high hall on the secure side of Terminal 2, planted with palms, with an expansive window wall onto the apron and Stuart Keeler’s chandelier sculpture hanging over the middle of it, a ring of steel pipe strung with tens of thousands of crystals. Local names sit alongside the chains, and the seating is the kind you can spread out in rather than perch on.

Terminal 1, which opened on 23 September 2025 with the first nineteen of its eventual thirty gates, does the same thing outdoors: twelve food and drink outlets, and a terrace where you can eat in the open looking over San Diego Bay to the downtown skyline. Its street front is a curved glass wall of 537 fritted panels designed by James Carpenter, which is worth a look on the way in whichever terminal you are flying from.

Two hours is a Sunset Cove connection and nothing more. If it turns out you have five, the city bus outside baggage claim reaches the downtown train station in about fifteen minutes, and the full San Diego layover guide covers the Embarcadero ships and Balboa Park within walking distance of it.

Spanish Landing Park, a mile of bayfront path

Spanish Landing Park runs along the West Basin on the bay side of North Harbor Drive, opposite the Harbor Island marina, and it is about 0.8 miles from the Terminal 2 door: out through the parking structure, across the road, and then a mile of paved path along the water with benches, grass and picnic tables. The far bank is a wall of sailboat masts, and the downtown towers stack up beyond the end of the island.

The park takes its name from 1 July 1769, when the Spanish party that had come by sea met the overland party up from Baja California on this shore; the ground is California Historical Landmark 891 as a result. It costs nothing and it never closes, and it is the only open-air option inside walking range of the terminals. The round trip is a mile and a half on pavement and through a parking structure, and it is a walk you want to be doing empty-handed rather than towing a suitcase.

Changing terminals means clearing security twice

The free inter-terminal shuttle picks up outside baggage claim at both terminals, roughly every fifteen minutes, and it is the only way across: the two buildings are not joined behind the checkpoints, so a terminal change drops you back into the public concourse and through TSA screening again on the far side. Walking between them is not currently an option either. The roadway and sidewalk linking the terminals closed in September 2025 for the next phase of the Terminal 1 rebuild, and the detours are scheduled to stay until that work finishes in 2028, after which the walking route is expected back.

If your onward flight leaves from the terminal you landed at, none of this applies and the whole layover stays behind one checkpoint. Check the terminal on your boarding pass before you settle into a seat: a terminal change wants fifteen to twenty minutes of slack on top of the screening queue.

The airport sits three miles from downtown and a few hundred yards from the bay, which is what makes both of those real here: a walk out to the water, or a fifteen-minute bus into the city. Either works better with your bag left behind a counter than rolling along beside you.
