I believe the entire loop distance is 2.7 miles
They also have access to a to a road that goes up to another lake at the top but I think you have to go to big sky just north of Poway lake entrance.
Just went fishing yesterday & read signs on hiking. It is a 8 mile hike going up and coming back down. It takes about 3 hrs to complete the hike.
There is another hiking trail from blue sky to potato chip rock which pass poway lake and it is 10 miles
Lake Poway Loop Trail is a 2.7 mile moderately trafficked loop trail
