Ride Report: Mammoth Creek / Sherwin Creek Loop

This is probably the best snow biking loop in town if you’re going to choose one ride to do on a fat bike in Winter.  It’s also a mellow Fall/Summer ride on a mountain bike.  It starts with a moderate descent and some flats to warm your legs up on Mammoth Creek Rd .  Then you’ve got a nice, gradual climb back up Sherwin Creek Rd.

  • Ride Type:  Loop
  • Difficulty:  Moderate with gradual climbing
  • Time of Year: All year
  • Terrain/Conditions: Summer/Fall – dirt roads, singletrack, bike path.  Winter/Spring – 95% snow, firm OSV & snowshoe packed
  • Access: From town, take Old Mammoth Rd. to Sherwin Creek Rd. (across from Mammoth Creek Park).  Go down Sherwin Creek Rd for 1/2 mile, turn right near the big propane tanks and park here.
  • Length: 10.2 miles
  • Approx. Time: 1.5- 2 hours
  • Lowest Elevation: 7,216′
  • Highest Elevation: 7,872′
  • Total Elevation Gain: 703′
  • Bike Recommendation: XC Mountain Bike in Summer/ Fall or Fat Bike in Winter/Spring
  • GPX File: Available by contacting us

Once you’ve parked, start pedaling back up Sherwin Creek Rd. to Old Mammoth Rd.  Make a right turn, and in 50′ turn right on the Mammoth Creek trail.  Stay on the trail for about 1/2 mile before reaching an intersection.  At the intersection stay right onto Mammoth Creek Rd.  If you go straight, you’ll stay on the town bike path – so make sure to stay right.  Once on Mammoth Creek Rd, it’s a no-brainer.  Continue down the road, while spying the White Mountains straight ahead, and the Sherwins, Laurel Lakes area and Bloody Mountain to the right.  If riding on snow, try to do this ride in the morning while the snow is firm.  It’s pretty exposed and gets sun affected easily.  Once down at the bottom, you get very close to the 395 highway.  Make sure to turn right and continue to the intersection with Sherwin Creek Rd.  Enjoy a mellow climb with more outstanding views.  You’ll pass by the turn-off to the Laurel Lakes Ride on the left.  If you have a death wish, you might want to add this lung-busting ride to your current loop.  If not, continue up past the YMCA camp, into a shaded, tree-lined section.  Once you pop out from the trees, you’ll get views of Mammoth Mountain, Lincoln Mountain, and Mammoth Rock.  Shortly after passing the trailhead for Mammoth Rock Trail on your left, you’ll approach your car, and think to yourself, “FAT BIKES ROCK”.  If you’ve still got gas in your proverbial tank, try adding on The Meadows Ride.  You might also consider doing the Meadows Ride first as a warmup.
