Since St Petersburg we have encountered just 2 yachts. Both small Russian boats with small outboard motors.
So Priozersk came as a surprise. Entering through a narrow but well-marked channel there are 3 small marinas here in the river, with dozens of small local yachts. We stopped at the first marina on the left, said to be the best of them. A decrepit timber mill looms large on the opposite shore and there is a medieval fortress worth exploring.
The marina has pontoon berths, shore power and rudimentary facilities (no water or fuel, though). Staff are friendly and there is an excellent restaurant nearby. A welcome change.
North from here there are myriad islands, sounds and byways begging exploration en route our northernmost destination, Valaam.
