Lake Elsina and Lake Dinah sit southeast of the Mission Mountain Wilderness and east of the Mission Mountain Tribal Wilderness. Both are near the Clearwater-Jocko Divide.

Lake Dinah is a popular snowmobile destination in the winter and offers a short hike with great views, wildflowers and fishing in the summer.

The trail begins at the parking area at Lake Elsina at 6,320 feet. There is no trailhead sign. Follow the only trail that follows along the east edge of the Lake Elsina.

The trail winds through lush undergrowth and dense high sub-alpine forest along several cliff bands and open meadows as hikers climb the pass that crests at 6,680 feet. By mid July the wildflowers have just started to paint the hillsides with bright reds, purples, yellows and white. A few residual snow banks fill in the low spots.

There are several areas of the trail still under an inch or two of water. Because of all the moisture, the mosquitoes are prolific.

As hikers descend the pass, they will have a view of the Swan Mountain Range to the east. Below is 36-acre Lake Dinah.

The trail continues through sparse trees along the ridge before descending to the northern shore of the Lake Dinah. There is a trail along the lake allowing visitors to camp at various locations and plenty of opportunity to fish and enjoy the water.
