The Presidio: the post and the Tunnel Tops
An old army post turned park — the Main Post, Goldsworthy's Spire, the Tunnel Tops, Crissy Field. This is a Claude-drafted route awaiting the editor's walk.

1. The Main Post and the Parade Ground
Start where the army did — the open parade ground ringed by red-brick barracks, a military post from 1776 under three flags. The oldest building, the Officers' Club, holds the original Spanish adobe walls inside. Get a coffee on the square and read the place before you walk it.

2. The Walt Disney Family Museum
On the parade ground's edge, in an old barracks — the story of the man, not the brand, with the multiplane camera and the early sketches. You don't have to go in, but if you do, it's the early Kansas City years that surprise people.

3. Andy Goldsworthy's Spire
Up the wooded slope above the post, a 90-foot mast of cypress trunks lashed point-up among the trees that will one day hide it. One of four Goldsworthy works in the Presidio. The walk up through the forest is half the piece.

4. The Presidio Tunnel Tops
The new parkland built on the lids of the highway tunnels, opened 2022 — meadows and overlooks that join the post to the shore without a road in the way. The bluff terraces frame the bridge dead ahead. Easily the best free view in the park.

5. Crissy Field
Down the steps to the old grass airfield turned shoreline, the restored tidal marsh on one side and the bay on the other. Walk the promenade east with the bridge over your shoulder. Windsurfers if it's blowing, which it usually is.

6. The Warming Hut and the Marina exit
Stop at the little café-bookshop by the water at the field's west end, or carry on east toward the Marina Green and the St Francis Yacht Club. Pick up the 30-Stockton on Chestnut for the ride out.
