September 7

Occoquan in Winter The map just keeps getting better! For our season opener, QOC will return once again to this family-friendly park with an improved map featuring new contour spacing and fieldwork by Jon Torrance. Final course details are now posted. All courses are in line with typical skill level difficulties, although the White course is a bit on the short side so any beginner wanting a bit more of a workout is encouraged to try the Yellow course.

Event timing will be standard: register anytime between 10:45 - 1:15, start between 11 - 1:30, and be back before the controls start being picked up at 3pm.

If you will be bringing a large group (youth or otherwise), please contact Event Director John Baker so that we can coordinate pre-registration for your group; the group registration and waiver form is part of the information on our Group Leaders page.

Grandparents Day Special!! Registration fees for grandparents orienteering together with one or more grandkids are at junior rates, and everyone in the group gets a map at no extra cost.

Occoquan Pavilion Additional information:

  • Free beginner clinics as always are available; just ask when you register.
  • Registration is at the pavilion shown in the photo.
  • Dogs are welcome, but please keep them on a leash at all times.
  • Full restroom facilities will be available a short walk away from the pavilion.
  • There are no entrance or parking fees at this venue.

Nearby attraction: The Lorton Art Center, perhaps best visited after the orienteering event. Turn right onto Route 123 when exiting the park, and then take the next right turn. When leaving the Art Center go out the side entrance and then turn right onto Lorton Road. Follow Lorton Road back to I-95 exit 163.

Take exit 160B off of I-95 onto Route 123 north, follow 123 north 1.5 miles to park entrance on right. As as alternative, from exit 163 make a left at the new traffic light onto Workhouse Road, and then go left at the next two traffic lights.

Be aware that I-95 heading south after ~11am on Saturday mornings is when the express lanes reverse, usually causing a back up starting at Route 123; avoid using I-95 between exits 160 - 163 on a weekend afternoon if you can.

Important Notes
  • At the event, we can only accept payment in cash or check; online, you may use a credit card or PayPal account.
  • You may become a member at the event or by joining online via this webpage (which also explains the member benefits). Membership is completely optional.
  • Most of our events use an 'epunch' timing chip for electronic timing. Individuals or groups without their own epunch pay a higher entry fee (see above), which includes the loan of an epunch for that event. Loaned epunches that are lost incur a $40 replacement fee. Epunches (also known as SI-cards or finger sticks) are usually available for sale at each event as described here.
  • Compasses are available at no charge, but if lost incur a $15 replacement fee.
  • Please provide collateral (driver's license or car keys) when borrowing a compass or epunch.
  • For additional safety, whistles are available for sale at $1/each.
  • Free beginner instruction is always available - just ask at the registration table.
