Greys River Snowmobile Directions from Trailhead

Half Day Trail Suggestions from the Greys River Trailhead

For our four hour half day rides we suggest checking out the McCain Cabin area down the Little Greys trail system. Start by cruising down the Greys River Road (A) trail. You will pass over the Greys River bridge in 1.5 miles from the trailhead. 2.2 miles past the bridge you will come to trail intersection (C) coming in from your right hand side with a small bridge crossing. (The (C) trail is designed for full day rental experienced backcountry riders only on performance and high-performance machines only- no trail or crossover sleds please). Continue straight down the (A) trail for another 3.5 miles until you reach the (D) intersection. The Forks Campground will be covered in snow on your right hand side just before the intersection. At the (A/D) trail intersection take the (D) trail to your left hand side (Black Arrows on our map). The (D) trail is also referred to as the Little Greys (FN-10124) due to following the little greys river system, a feeder to the greys river. This trail slowly climbs in elevation for 14 miles until you reach the McCain Cabin Guard station. This is a great area to enjoy a picnic lunch or snack. There are beginner friendly meadows for off trail riding as well. You will pass by Bull Hollow (6.7 miles in) on your left hand side. (Bull Hollow is designed as a short cut to the McCain cabin but should only be used by experienced riders on performance and high performance machines) If you are on a trail sled or crossover continue straight down the (D) trail. 5.2 miles later you will come to a split in the trail system. Continue on the (D) trail to your left. (FN10047 goes right to a dead end). Continue 2 miles until you reach a split in the trail system. At the split stay left and the guard station will be down 1700feet.  The guard station is locked to the public. There is an open restroom at the cabin open to the public. To exit back to the (A) trail simply backtrack on the same (D) trail back to the greys river intersection (14 miles). Here you will make a right onto the (A) trail and be back to the town of Alpine in 8.1 miles.

You also have the option to skip the Little Greys Trail system at Intersection (A/D) and simply continue down the Greys River Road on the (A) trail (Blue Arrows on our map). This will be the easiest route to follow. The Greys River trail (A) continues groomed for around another 30 miles. You will pass by the Lynx Creek campground on your right and the Murphy Creek Campground on your right. 7 miles later you will pass the Moose Flat Campground on your right. 3.8 Miles past Moose Flats will be the (A/E) intersection for Blind Bull. This is a good intersection to turn around and head back towards Alpine. Make sure to watch your time and give yourself enough leeway to make it back to the shop!

Beginner/ Intermediate Total 56 miles out and back

You will pass over the Greys River bridge in 1.5 miles from the trailhead. 2.2 miles past the bridge you will come to trail intersection (C) coming in from your right hand side with a small bridge crossing. (The (C) trail is designed for experienced backcountry riders only on performance and high-performance machines- no trail or crossover sleds please). Continue straight down the (A) trail for another 3.5 miles until you reach the (D) intersection. The Forks Campground will be covered in snow on your right hand side just before the intersection. At the (A/D) trail intersection continue straight on the (A) trail.

Full Day/ Multiple Day Backcountry Off-trail Access

For Intermediate/Experienced/Expert Riders

Quickest access to the backcountry starts by cruising down the Greys River Road (A) trail. You will pass over the Greys River bridge in 1.5 miles from the trailhead. 2.2 miles past the bridge you will come to trail intersection (C) coming in from your right hand side with a small bridge crossing. Take the right onto the (C) trail crossing the bridge and heading up the mountain. The trail goes up and over Squaw for a total of 11.8 miles bringing you out close to the Murphy Creek riding area. From Squaw you can access intermediate up to expert terrain right off the trail. When you come down the back side of squaw the trail will dead end you into the murphy creek trail (FN-10002).  From here you take a left and it will lead you back to the (A) trail. Once back to the (A) trail if you take a left you will head back towards the (D) trail (Little Greys) in 6.4 miles or all the way back to Alpine 14.5miles. If you turn right you will head towards Blind Bull (E), and Box Y. Remember when riding in those areas to watch your fuel! Fuel is available for sale at the Box Y Lodge if you are running low or plan on riding the E, H, or N trail systems.

Another great option on a clear day for full day off-trail riders is the Blind Bull trail (E). This trail intersects on the left with the (A) trail at 26 mi.  Once you take the left onto trail (E) you will follow this 7.7 miles winding your way to the top of the mountain and coming to a Log Warming Hut with a restroom.  You can pop into the warming hut to warm up and take a break from the elements if you desire!  There are ample amounts of off trail options up here, being cautious off-trail of the risks all around! You will come back down using the same trail you did going up! KEEP AN EYE ON YOUR FUEL LEVEL!! AVOID this trail during white-out conditions.
