Now here is a real gem tucked away on the very edge of the Jefferson Wilderness Area. This is a short hike and barely ranks as moderate. The hike to Triangulation Peak is family and pet friendly.

From the trailhead it is about a mile and a half to the junction which takes you off of Trail 3373 and onto Trail 3374. It is about another half mile to the summit.

In early July this hike is adorned with incredible floral displays. As soon as you leave the parking area, the trail descends for about a half mile through fairly dense forest. Then the trail begins to climb gently for another mile to an obvious junction.

At this junction, bear to the right, and head uphill for another half mile to the top of Triangulation Peak. The views are breath-taking and so worth the effort.

If you want to venture to Boca Cave, well, that's another matter. This is not an established trail and it is not family or pet friendly.

A couple hundred feet back down the trail from the summit of Triangulation Peak a user's trail bears off to the right, or east, and will take you to Boca Cave. The user's trail descends steeply through dense forest to the bottom of a cliff into which you will find Boca Cave.

Northwest Hiker does NOT recommend the hike to Boca Cave for anyone who is not in excellent physical condition and has a vast amount of hiking experience.
