Pėsčiųjų takas, Kurzeme
Sēra dīķu taka is a wooden boardwalk trail through Raganu purvs (Witches' Bog) in Ķemeru National Park, Lapmežciema pagasts, following a roughly 700-metre zone of natural sulfur springs. The springs feed several ponds covering about 0.5 hectares, part of the wider Ķemeri-Jaunķemeri sulfur-water deposit; in spring the water can appear yellow from microorganisms. The renovated boardwalk runs about 2.5 km and, for nature protection reasons, is normally visited only with a park guide.
