This is a nice State park with several hiking/walking loops and/or trail running loops that are accessible from the McGregor Viewpoint. I recommend hiking the longest loop to Fall River Falls before exploring the other loops.
Angelique, Zoe, and I enjoyed a quick hike through LaPine SP on a cool and cloudy day in June. Before heading out on the loop hike we enjoyed the view of the Deschutes River from the McGregor Viewpoint and the distant views of Paulina Peak. The first mile or two of the trail to the Fall River Falls passes through a dense forest of lodgepole and ponderosa pines and is a bit spooky since you can’t see much other than thousands of trees in every direction. Sometimes referred to as a “Human GPS” by my friends, I felt a bit lost during the first mile or so of the hike due to the numerous trail junctions and trail crossings near the McGregor Viewpoint. After regaining my bearings I enjoyed the moody forest and the meandering trail and made a mental note to return for a trail run. After a nice stretch along the Fall River, followed by a long forested stretch, we eventually arrived at the very
scenic Fall River Falls. Not a large cascade by any means, Fall River Falls is definitely a nice spot to rest and to enjoy Fall River. The hike back to the car (partially along the Deschutes River) was very relaxing but both Angelique and I wish the “official” trail had passed by the confluence of the two rivers.
