After visiting Zajac Ranch, I dropped by Rolley Lake Provincial Park to see the waterfalls. Both the ranch and the park are close by each other and on the west side of Stave Lake. Since I’ve travelled this far, I might as well go hiking to see Rolley Lake Falls. :D Check the map below for direction. I found out the trail head to the waterfalls was closer to the camp site than to the visitors parking. If you start at the visitors parking, you have to walk the full length of lake shore to reach the trail head of the waterfalls.
The hiking trail head (camping site) to Rolley Lake Falls is not very obvious due to lack of sign. The exact trail head location is indicated by Green Arrow on the following map (click EXTERNAL LINK below to view map). At that corner of camping site, you will see a toilet and a big garbage dumpster. The trail head to the waterfalls lies between the toilet and the garbage dumpster, with a huge tree trunk lying across the trail. Hop over the trunk and follow the trail, until you reach a fork; the left trail of the fork takes you to falls and the right trail takes to Stave Lake.
