Activity Notes

We will carpool from the MMC, leaving at 7:30 AM.  We'll drive to Deschutes River State Park off of I - 84, past the Dalles.  We'll start our hike at approximately 9 AM, on the Deschutes River Trail (Rails to Trails Trail).  We will hike approximately 10 miles total, 5 miles out and back, at a moderate pace 2 to 2.5 mph.  Expect exposure to the weather throughout the hike.  The hike has a very gradual incline, but for the most part is flat.  The cliffs, river and canyon are quite striking throughout.  Good opportunities for photos.
