The trail around Oquirrh Lake in the Daybreak Community of South Jordan (a suburb of Salt Lake City) is a quiet and beautiful place to enjoy a run or ride. The distance around the perimeter of the lake is approximately 3.2 miles, but there are bridges that cut across it in several places, making it easy to tailor the trail for any distance.
When visiting the greater Salt Lake City area, a great place to get some exercise and explore is Antelope Island. With an extensive 20+ mile trail network of varied difficulty, this makes for a great place to log some trail miles on foot or on a mountain bike. If you decide to visit Antelope Island, you will be awestruck by its beauty and the vastness of the Great Salt Lake. Be sure to check the website for gate hours as it varies by time of year.
