Stoco Fen Provincial Park is a 203 hectare nature reserve established in 1985. Ontario Parks places the wetland complex 3 kilometres east of Stoco Lake and 6 kilometres from the village of Tweed.
The official page says most wetland vegetation is mixed swamp forest, with cedar swamp predominating. In the eastern part of the wetland is an open fen complex covering about 50 hectares.
Stoco Fen is a specialist wetland reserve for people interested in fen ecology, rare plants, and protected lowland habitats. Ontario Parks describes the open fen as a mosaic of sedge meadows, shrub thickets, marl-bottomed pools, and islands of stunted cedar and larch trees.
The fen has high plant species diversity and provides habitat for a number of provincially and regionally rare plant species. That makes the park important for natural-history research and low-impact interpretation, even though it is not a developed destination.
Ontario Parks says there are no visitor facilities available. Planning should start with that fact and with the fragility of wetland surfaces, where casual wandering can damage the feature that the reserve protects.
Keep the visit brief, dry-footed where possible, and driven by protection of the wetland.
Plan around wetland study, plant-interest research, map review, responsible photography, fen interpretation, cedar swamp context, and very low-impact nature observation where official access guidance allows.
Confirm access, no-facility limitations, wetland protection rules, maps, alerts, weather, appropriate footwear, communications, and emergency planning through Ontario Parks before travelling.
