6 guides, each rated 1 to 5 with the reason — and two lists per place, where you are comfortable and where to pay attention. Nowhere is called dangerous; the specific thing is what helps.
Very comfortable. Karosta at night is empty rather than unsafe; the Northern Forts are unstable concrete and the sea takes a piece every year; the beach has rips in a west wind. That is the list.
Comfortable: the centre · the beach
the Northern Forts — unstable concrete over the sea
Very comfortable, and the old town is walked late. The old town bars that exist for stag parties overcharge and occasionally worse — choose the bar, and never the one whose promoter found you. Pickpockets in the market crowds. Ice on the pavements in winter.
