Priest Lake State Park lies just 30 miles from the Canadian Border, nestled deep below the crest of the Selkirk Mountains. Surrounded by the natural beauty of Northern Idaho and mile-high mountains, Priest Lake State Park sits along the eastern shores of Priest Lake, a 19-mile long, over 300 foot deep lake. Visitors to the park will enjoy the dense forests of cedar, fir and tamarack and will be able to observe the park's year round inhabitants such as the whitetail deer, black bear, moose and bald eagles. Noted for its extremely clear water, fed by streams cascading from the high Selkirk peaks, the main body of Priest Lake extends north south for 19 miles. A two-mile thoroughfare connects the main lake to the remote Upper Priest Lake that is accessible only by foot, mountain bike, or boat.
The loop on the map is the parking lot. This is an easy flat path that winds through an old cedar and pine forest. The trail is an easy mountain bike trail. The trail is straight north up to the southwest corner of Upper Priest Lake and up along the west bank as far as you like. You can actually swing around the east side and come south but unless you want to swim across the passage(That's the creek that connects both lakes) you will have to have another vehicle waiting on that side.
