Trails and Size

The trail-map page calls the park “a favorite destination for hikers and mountain bikers of all ages and fitness levels” with “nearly 65 miles of trails.” The park page says “about 60 miles.” We show both. The park is 8,000 acres. See the Visitor Center page and Cowles Mountain, the park’s high point.

Heat and Dogs

Mission Trails’ own article on hot trails and dogs says on the hottest days the safest choice may be to leave your dog at home. The park’s leash rule is not confirmed here.

What We Could Not Verify

  • Mileage differs between park pages (“nearly 65” and “about 60”). Mission Trails Regional Park can confirm.
  • Individual trail lengths, dog leash rule and trail fees are not confirmed.
  • A news headline on the park home page mentions reconstructing the South Fortuna stairway; whether any trail is closed was not read. Mission Trails can confirm.
