Pros & cons

Park at the Elkwood Amphitheatre day‑use lot just past the Discovery Centre; follow the signed 0.8 km connector to the loop. If staying in Elkwood Campground, the loop trailhead is between campsites C and D.

Overview
A gentle forest-and-wetland stroll to a pretty lakeshore, this interpretive loop is the park’s easiest way to stretch your legs and learn a little ecology. The official loop is 1.5 km (about 0.9 mi). Most visitors start at the Elkwood Amphitheatre day-use lot and add a signed 0.8 km connector each way, bringing the total outing to roughly 3.1 km (about 1.9 mi) round-trip. Expect minimal elevation and plenty of mountain-peek views through the trees.
Route
From the Elkwood Amphitheatre parking, follow signs about 0.8 km to reach the start of the loop; the initial wayfinding can feel a touch confusing, so keep an eye out for “Marl Lake Interpretive” signage. The circuit winds through mixed forest and wetland boardwalk-style sections to the lake, where a small dock and benches invite a linger. If you’re camped at Elkwood, you can hop on the loop directly between campsites C and D.
Accessibility
The path is wide and hard‑packed—stroller‑friendly and generally wheelchair‑friendly with a companion to help on short grades. Stairs down to the water have a bypass, and there are benches for breaks.
Best Time to Hike
Officially listed as a summer‑only interpretive trail; late spring through fall (roughly May–November) offers the most reliable footing. It’s popular for easy walks and runs, and the interpretive panels make it a good family pick.
Know Before You Go
A Kananaskis Conservation Pass is required to park. Dogs are allowed but must stay leashed. Bikes aren’t permitted on the interpretive loop. Group size is limited to 35. In winter, the trail isn’t maintained. Expect damp sections near the wetland; waterproof footwear helps. From the Amphitheatre, bring a simple map or pay close attention to signs to avoid a wrong start.
A note on the “marl”
“Marl” is a calcium‑carbonate‑rich mud that forms in mineralized waters; interpretive signs along the route explain how this geology shapes the lake and surrounding wetland.
