YOUR VISIT, YOUR WAY

What would you love to do here?

Saint Mary Lake is worth visiting for expansive water views, Wild Goose Island scenery, and access to nearby viewpoints and trails. Choose a quiet independent overlook or add a boat-based experience, depending on how much hiking and coordination you want. Water remains cold year-round, so use required PFDs when boating, supervise children closely near shore and steep edges, and check current road, trail, seasonal boating, and access conditions before visiting.

Sun Point viewpoint and nature trail

Visit Saint Mary Lake independently from Sun Point for an overlook and a 0.9-mile-one-way nature trail; no boat booking is needed, but the trail is not a loop and park entrance fees may still apply.

Saint Mary Lake lets you choose how closely to explore Glacier’s eastern lake scenery. Sun Point offers a viewpoint and a starting point for lakeside and waterfall trails; Rising Sun is the departure point for the operator’s scenic boat tours. Choose a viewpoint stop, a hike with a clear trailhead and endpoint, or a cruise before adding it to your day. A waterfall hike from Sun Point is not the same distance as one from a different roadside trailhead.
