Park near the gates to Fortis owned property [N 49° 28.235 W 117° 28.222]. Obey the signs and stay out.
Public access to the lower part of this creek is via an ATV trail and a power line right-of-way. Walk along Corra Linn Road to the red ribbon marking the ATV trail. Turn onto the trail but watch for a walking trail going off to the right almost right away. Drop down that trail past four viewpoints of the falls. The cache is on the other side.
Go all the way down, skirt the pool at the bottom, then climb up the other side. There's two more viewpoints on that side. The cache is hidden in between them.
This creek is named Falls Creek, at this point the name is very appropriate.
Going back, do not go up from the cache. That is Fortis property and they have posted no trespassing signs all over. Please respect that by going down and back up the other side of the creek. It's worth it because you'll get more chances to look at the falls.
