Hundreds of black pools set in an 8,000-year-old Latvian moss bog, crossed on a boardwalk between pines a century old and no taller than you.

September·Peaking now

Sep–Oct

The bog's finest hour: the vegetation burns amber and gold, and geese and cranes stream back south from late September into October.

Year-round The peat-brown pools, dwarf pines and boardwalk are here every day, free and open around the clock and never cleared of snow — but the pools freeze in winter and mosquitoes own the summer dawns.

The Great Ķemeri Bog is a raised bog of 8,000 years of moss in the Ķemeri national park west of Riga, in Latvia, a dome of peat set with hundreds of black pools and crossed on a boardwalk between pines a century old and no taller than a person, with a tower halfway round for the view over the pools, and it is walked on a short arc of 1.4 kilometres or a long one of 3.4, best at dawn in autumn when the mist lies flat over the water. A raised bog takes no water from the ground below, since its dome sits above the water table and lives on rain alone, which is why so little grows here and why the pines stay dwarfed, and the planks carry the walker over ground that would swallow a boot to the knee; the pools are dark with peat and mirror the sky, the tower lifts the eye above the pines to count them running to the horizon, and beside the boards in the wet moss grow the sundews, rosettes the size of a coin, red-haired and glistening, that catch and digest insects. The heavy resinous scent along the planks is wild rosemary, which in quantity can leave the walker light-headed. The bog's sulphur water turned Ķemeri into one of the fashionable spa towns of the Russian Empire. Wood sandpipers and golden plovers display over the open moss through late spring, nesting almost nowhere in Latvia but raised bogs, and geese and cranes cross the bog in their thousands in March and April and again from late September, heard before they are seen; hare's-tail cotton grass turns the hummocks white through June, and by late summer the heather runs the same ground purple. On a still clear autumn night the moss sheds its heat and by dawn mist pools over the darker water, burning off within an hour or two of sunrise. Ķemeri is a bog that drinks only rain, and the boardwalk is the only dry ground.

Worth knowing

Good to know

Come at first light and the bog is yours — the mist sits lowest in the first hour, and by mid-morning the narrow planks fill with walkers coming the other way.
The car park is paid and sits 800 metres short of the boardwalk — allow that walk each way, or ride the train to Ķemeri station and walk in from there.
The boards have no railing and turn greasy when wet or frosted — wear shoes that grip, and remember snow is never cleared here in winter.
Only the long 3.4 km loop reaches the tower — the short arc never gets there, and the flat panorama from the top is the one view the planks cannot give you.
Bring repellent from June to August — the standing water that makes the pools also breeds mosquitoes, and dawn and dusk, the best light, are their best hours too.

Things to do

1
Step out onto 8,000 years of moss
The planks carry you over ground that would swallow a boot to the knee: 1.4 kilometres on the short arc, 3.4 on the long one. Crouch where a pool comes closest to the boards and the water is tea-brown with peat, so still that on a windless morning it reflects the clouds almost exactly.
2
Climb the tower and count the pools
Halfway around the long loop a wooden tower lifts you above the pines. From the top you see the whole bog at once: hundreds of black pools spread over the flat moss, the boardwalk winding between them, and forest only as a distant rim.
3
Pick the waders out of the open moss
Wood sandpipers and European golden plovers nest out on the open moss. In Latvia these two birds breed on raised bogs and almost nowhere else. Scan the flat ground beyond the planks early, and listen: the plover's thin whistle carries a long way over moss.
4
Find the sundew that eats insects
Look down at the wet moss right beside the boards for a rosette the size of a coin, red-haired and glistening. The round-leaved sundew cannot get nitrogen from this starved ground, so it takes it from the flies that stick to those hairs.
