Grunt's Grove is a primitive wilderness campsite located approximately 4 km upstream from the trailhead along the Carmanah Valley Trail in Carmanah Walbran Provincial Park, British Columbia.

It sits on the banks of Carmanah Creek, past the Three Sisters Sitka spruce and beyond the maintained section of trail. The site is defined by a majestic stand of old-growth Sitka spruce and an adjacent gravel sandbar where camping is available.

Spruce seedlings can be found establishing themselves on the sandbars — the typical starting point for new spruce growth in the valley. Large logjams on the creek are also visible nearby.

Facilities are nonexistent; there are no pit toilets and no campfires are permitted. The unmaintained trail leading here involves log scrambles and detours around riverbank erosion, making it a true backcountry experience suited to self-sufficient campers.
