They were. For the unlovely hilltop bus terminus that is Taksim Square, where thousands of protesters were fighting to save their only park becoming a mall, and by extension defying a government they see as authoritarian and conservative, is not found on too many tour bus routes.
In our hostel a passionate young American tried to engage the staff in discussion about the reasons for the uprising. They found tables to clear, dishes to wash. Turks are notoriously reluctant to discuss their domestic politics with strangers, and sometimes with each other.
On Sunday more intrepid travellers took the light-rail and climbed the steep paths and stairs to Taksim, the old city's newest tourist attraction. Some helped locals prise pavement bricks and stockpile them. They gawped bemused at the overturned and burnt-out city buses and the makeshift barricades of building materials, probably the largest inorganic rubbish collection in Istanbul's 5000-year history. They posed for smartphone photos and asked passers-by to take a snap of the two of them together. Three local brothers - the oldest 10, their faces masked by football scarves - pretended to drive one trashed vehicle while their father took their picture through the smashed windscreen. Cheering speeches, blowing whistles, and waving professionally made and hastily contrived banners, protesters covered every square inch of the scrubby park that may or may not become a paved paradise.
There was not a policeman in sight but in true Turkish fashion the street vendors - the water sellers, the sesame seed bun men, the chestnut roasters - had set out their stalls.
Thousands more supporters streamed up the hill past Besiktas football stadium to join their heroes. For possibly the only time, Istanbul's drivers gave way to pedestrians - though they had no choice - as they blocked usually busy roads to reach their target. They even tooted their support.
It was only 20 degrees on Sunday afternoon. It feels as if this could be a long hot summer in Istanbul. The tourists in the squares outside the Spice Market and the Basilica Cistern, following the clues in Dan Brown's latest novel, may not notice the inferno.
