The 2 mile loop around the Sparks Marina Park Lake makes for a pleasant run, with good water and mountain views. Sparks is a town about 5 miles east of Reno. There is an easy to follow path, mainly paved, around the lake, which is popular for fishing, diving, boating, and volleyball. A great spot for swimming in warm weather. Easy parking, or bus access from Reno. There’s a casino on the west end of the park and a shopping mall on the east end.
