Long Island City is the closest Queens gets to Manhattan, and it has the best seat in the house: the whole Midtown skyline, straight across the East River, with nothing in the way. Three and a half kilometres from the water back to the trains, with the art that's quietly filled the old factories along the way.
Start at Gantry Plaza State Park, where the East River pulls right up to your feet and the black loading gantries — kept, repainted, lit — frame the view across to Midtown. Walk the railing north to the PEPSI-COLA sign, the red neon survivor of the bottling plant that used to stand behind it. The NYC Ferry pulls in along here; ride it later if you want the harbour. Then turn inland to where 5 Pointz used to be — the graffiti warehouse, whitewashed overnight and gone now, a glass tower in its place. MoMA PS1 is the payoff: contemporary art in an old schoolhouse, radiators and all.
End at Court Square, under the blue-green Citigroup tower, with three subway lines underneath. Do it towards evening, when the skyline you walked in on switches its lights on.
