The larger of the two lakes tucked into this northeastern corner of the park, Emma Matilda Lake offers excellent wildlife habitat, rolling terrain, and a splendid backcountry waterfront. We like starting from the trailhead on Pacific Creek Road. Head for the north shore first to hike it counterclockwise, looking out for ripe thimbleberries in high summer—but be aware that bears love them too, so practice good bear safety. Hike through aspen groves and up a steep ridgeline with birds-eye views over the lake, then swing south through sagebrush meadows. The southern shore is primarily a thick spruce/fir forest, save for the sweeping vantage point of Lookout Rock. You can also combine this loop with a circumnavigation of Two Ocean Lake for a much longer trip.
