Hiking in Marten River Provincial park: trails, map and practical info

The Trail Network

The park's trail system consists of interconnected trails that all start at the same trailhead. Hikers follow color-coded routes: the yellow trail (0.8 km) for a quick walk, the red trail (3.5 km) for a moderate option, and the blue trail (4.2 km) for a more extended exploration, with an orange route marking the exit. The elevation gain ranges from approximately 30 to 73 meters depending on which route you choose. This modular approach means you can adjust your outing based on time, fitness level, and interest without needing separate trailheads.

The Transition Trail is the park's standout route and earns its name honestly. It guides you through the ecological boundary zone that defines this part of Ontario, where southern hardwood species — white pine, maple, birch, poplar — gradually give way to boreal characteristics like balsam fir, black spruce, and jack pine. That shift happens subtly as you walk, and once you start noticing it, the trail becomes more interesting. Several viewpoints along the route open up over the surrounding wetlands, giving you a clear look at the marshes and small lakes that make up the Marten River watershed. These are the spots where you're most likely to see wildlife, especially if you're moving quietly and not in a rush.

The Old Logging Trail takes a different approach entirely. It follows historic routes used during the region's logging era, when massive white pines were felled and floated down the Marten River to sawmills downstream. Interpretive signs along the way explain how that industry operated and how it shaped the landscape you're walking through today. The surface is relatively flat and wide, making it the more relaxed option — good for families or anyone who wants to cover ground without much effort while still getting something out of the experience. Note that signposts marking points of interest exist throughout the trail, though some paper inserts may be missing, and the trail can become overgrown in places but remains easy to follow.
