This is a true leg-stretcher, not a destination hike: a short, easy loop on boardwalk and flat paths around tiny, brilliantly colored Olive Lake. It sits right at the summit of Sinclair Pass, about 12 km north of Radium Hot Springs, and doubles as a day‑use stop with picnic tables and washrooms. Dogs are allowed on leash.
Expect a quick, family‑friendly stroll with lake‑level viewpoints and an interpretive feel. The water is strikingly emerald/teal and often so clear you can peer down to rocks near the shore. From the boardwalk you may spot fish—historically brook trout have been common—while ongoing aquatic restoration aims to support native westslope cutthroat trout. Surroundings are forested and calm when traffic is light.
Plan on roughly 0.3 miles total for the loop with almost no elevation change (about 5 m/16 ft). Most visitors spend 10–20 minutes here, including time at the viewpoints. Surfaces are primarily boardwalk and flat paths with accessible infrastructure at the day‑use area, making this suitable for strollers and many mobility levels.
May through October is the sweet spot for access and color. For photos and a quieter feel, go early or late in the day when the lake is glassy and crowds thin. Midday can be busy thanks to the convenient roadside pullout.
Bears do frequent the broader area at times, so keep dogs leashed, give wildlife space, and respect any temporary closures. Stay on the boardwalk to protect the fragile shoreline and keep the water clear for fish viewing.
Signed day‑use pullout at the summit of Sinclair Pass on Highway 93S; toilets on site.
Bears occasionally prompt temporary closures; use the day‑use lot (not the highway shoulder) and keep dogs leashed.
