How to avoid the worst of it today

Walk the full wall line. Paseo del Morro's cats and sea gate, the cemetery's marble against the Atlantic, the kite field — the fortress perimeter as one unhurried arc.
Eat down the calles slowly. Mallorca breakfast, mofongo lunch, a piragua in the plaza — the old city as menu, taken at calm-day pace.

Where the crowds are

The Cristo and Fortaleza blocks: The pier flow's main channels.
El Morro's vaults at midday: The famous fort's inner squeeze.

Quiet places in San Juan
