Sphincter Rock is an intermediate x-country ride located in the Mosquito Lake Area. Most riders use this trail as an up track to reach the more advanced trails in the area; including Freak Boy, Grumpy Grouse and Cream Puff. Combine Sphincter Rock with Scruffy’s Bypass to make your way over to Rock and Roll and up along Rock and Roll to Econoline. From Econoline choose your own adventure as you decide which trail to descend.

Sphincter Rock has several steep climbs up the tight singletrack and long sections of slab. There is a tricky technical rocky descent found just after you pop out of the woods onto a rock bluff offering up a beautiful view of Ivey Lake. This section may be walked and is sure to challenge even the more advanced rider. After that you will near the trailhead for Scruffy’s Bypass heading up the rock slab to your right. I recommend riding Sruffy’s Bypass from here, as it is a much nicer trail from this point forward. If you choose to stay on Sphincter Rock, please note that this section of the trail gets a bit overgrown during the summer months and doesn’t have the same sort of flow that Scruffy’s offers. It will meet up and cross Scruffy’s only a few hundred metres down from Scruffy’s junction. Cross Scruffy’s Bypass to continue on down Sphincter Rock till you reach Strawberry Fields, or take a left onto Scruffy’s Bypass to access Rock and Roll; the better option, dependent on what you plan to ride.

Access to Sphincter Rock is directly off of the Mosquito Lake Road. Take Reid Road to Linda Road, turning left onto Linda Road. Ride a few hundred metres up Linda Road to Mosquito Lake Road. Turn right onto Mosquito Lake Road and head east for about 250 m until you see a wide and loose doubletrack heading up the side of the hill. Take this doubletrack and ride up it until you come to the trailhead for Sphincter Rock, heading right 150 m up the climb.
