East Boulder and Upper Boulder Lakes Trail is a 7.9 mile lightly trafficked loop trail located near Callahan, California that features a lake and is good for all skill levels. The trail offers a number of activity options and is accessible from June until October. Dogs are also able to use this trail.
Unlike some of the deep, rocky cirques found elsewhere in the Trinity Alps, East Boulder Lake and its smaller siblings sit in the middle of a sprawling basin with plenty of open meadows and commanding views. The short hike is well worth the effort for this very different setting. Free wilderness permit required for overnight visitors. Free campfire permits required for fires and camp stoves. Trails in the Trinity Alps are always open: however, most trailhead access roads are closed or impassable during winter.
