Things to Do in San Juan
Prices, opening hours, best times to visit and the stuff nobody tells you, everything you need for a first trip to San Juan, Puerto Rico, plus one pigeon's opinions on all of it.
Right, San Juan. Old fort walls, blue cobblestones, salsa spilling out of every open doorway, a Spanish colonial capital defended by centuries of fortress engineering, paved with an unusual blue-tinted stone repurposed from old ship ballast. This is the proper, no-nonsense guide to things to do in San Juan: what things actually cost, when to go, what to skip, and which bits are worth the walk. Three main stops below, plus a quiz elsewhere on this site to see if you were paying attention.
Castillo San Felipe del Morro
San Juan's old town is dominated by a massive Spanish fortress overlooking the harbour, Castillo San Felipe del Morro, a striking piece of colonial military architecture, walls up to 18 feet thick, worth a proper couple of hours exploring the levels and tunnels.
The wide grassy field in front of the fortress is worth a visit in its own right, a popular spot for kite flying, offering sweeping views over the walls and out to sea, particularly good at sunset.
Hours Daily, roughly 9am–6pm

The Blue Cobblestones
San Juan's old streets are distinctively paved with cobblestones made from ship ballast slag, worth appreciating this unusual material choice, the blue-grey stone, actually a byproduct of iron smelting used to stabilise ships crossing the Atlantic, was recycled into paving once ships were unloaded in the harbour.
The streets have taken on this distinctive tint over centuries, worth a slow wander through Old San Juan specifically to notice this detail underfoot, a distinctive piece of colonial-era recycling still visible today.
Best time Morning or evening for softer light on the blue stone

Puerto Rico's Political Status
Puerto Rico, including San Juan, holds unincorporated US territory status in relation to the United States, residents are US citizens but the island's political status remains an ongoing debate, worth understanding this context, Puerto Rico uses the US dollar and residents hold US citizenship, though the island doesn't have the same voting representation in federal government as the 50 states.
This shapes daily life and politics on the island in ways worth being aware of during your visit, worth engaging with local perspectives if the topic comes up, opinions on the island's status vary widely among residents themselves.
Best time to visit San Juan
December through April gives the most comfortable weather for the amount of walking this list involves, less humid and with a lower risk of hurricanes than the summer months.
Hurricane season runs roughly June through November, worth checking forecasts closely if travelling during these months, though prices tend to be noticeably lower in the off-season.
