The Centennial Ridges Trail in Algonquin Park is one of the best trails for sheer number of pristine lookouts. Photographers flock here for amazing vistas overlooking lakes and rolling highlands. One of the most popular times is during the fall colour season. Timing of peak colours is best handled by frequently checking the Algonquin Park Fall Colour Report. Usually it’s the first week of October (give or take) depending upon weather and drought conditions.
The Centennial Ridges Trail is a tough trail especially if you are carrying photographic equipment and you are hiking the trail during hours to catch the morning sun or sunset. The entire trail is 10 km and I think it might be the toughest 10 km I’ve ever hiked. The guidebook says allow 6+ hours although my wife and I hiked it 4 hours with frequent photography stops. The guideposts are numbered 1 to 12. Two of the best (and most accessible) lookouts are near the start and near the end of the trail at guideposts 2 and 11. The hike is approximately 1 km to guidepost 2 and 1.5 km to guidepost 11. If time is short and you wish a quality vista shot check these two spots first. If time allows hike the entire trail. Wear good footwear since often times the rocks are slippery.
