Tannen Lakes Loop Trail is a 5.5 mile moderately trafficked loop trail located near Cave Junction, Oregon that features a lake and is good for all skill levels. The trail offers a number of activity options and is best used from June until November. Dogs are also able to use this trail.
35.5 miles south of Grants Pass on Hwy199 take left on Waldo rd/Happy Camp Rd for 17.5 miles then left on signed Bolan Lake Rd.At about 4 miles arrive at junction with Bolan Lake to left but take right for about 3 miles then left to dead end at about 1.5 miles. Trail is about 100 feet before end.
First of all, the trail is a little less than 3 mile round trip plus it's only accessible from about early June until perhaps November, not year around as described. The road is the same as to Bolan Lake but at a signed fork in the road approaching Bolan campground, take the road to the right for about 3 miles and then left for about 1 1/2 mile. The road is blocked and the TH is about 100 feet before block. The trail does a fairly easy climb 1/2 mile to Tannen Lake. There's only a couple of possible campsites here that are decent as the lake is surrounded by brush and rock. If you take a left at the lake, across a stream , there is a trail that continues about 1 mile to East Tannen Lake. This again is a bit of a climb but easy. East Tannen Lake is similar to Tannen but smaller and without real camping potential. I did a backpacking trip a few years back starting at this TH and continuing to Sucker Creek Shelter and then down to Steve's Fork Tr. and on to Azalea Lake and then to Lonesome Lake, Kangaroo Springs and down Horsecamp Tr. in the Applegate. An absolutely great trip.
