Doctor Livingstone has been heading to the falls each year for many years. He's taken a number of different routes to get there - most of them difficult. But thanks to the good old GPS receiver he found an extremely well groomed trail for all to take from now on (known to all of the ATV'ers for years since they've kept it well travelled).
When arriving in Welsford on the #7 take the 101 North. You will cross a bridge and quickly come up to Sullivan Rd. on your left. Take Sullivan Rd. to the end and park there. The trail continues on where the road ends. Take the trail / BIG OPEN EMPTY SECTION for awhile until you come to an opening where the power towers are. Continue on the trail veering to the left and follow the towers for a bit. The trail will come to a fork - take the left and head back into the side of the woods you came from. Following this trail you will come to a roofed in stack of logs. It would be best to take a right out of the woods now towards the roar of the falls as going straight on the trail will take you to an abandoned cabin 100 ft away.
The trails are full of Bluberries once they are in season. We spotted some that were ready on the Canada Day weekend, so adjust accordingly if you want to be there to pick some.
Once at the edge of the river you can follow it down passing in front of the cabin. You will soon see the falls. This part will be the most difficult part of your trip because the sheer cliffs down to the bottom of the falls are relatively close to you on your right. Take in the falls and look behind you now for the cache.
The cache is an empty large plastic peanut butter jar with a blue cover. I could only get plus/minus 9 meters or so so you will probably need the hint.
