Eastern Sierra Mountain Biking Report & Information Guide

Wednesday, May 22nd, 2023 @ 8 AM – Happy Spring to all the local and traveling Mountain Bike Crowd. As of this update, most mountain biking trails and OHV roads below the 8200-foot level are ready to ride from Mammoth Lakes down to Bishop.

Above that level, there is still 2-3 feet on the ground at the 9000 foot level. As the area warms up we expect the snow line to come up quickly over the next couple weeks to around the 10,000 foot mark.

With the snowpack around the average mark this season, all trails and routes in the Eastern Sierra and the Mammoth Mountain Bike Park will be open earlier than later. This will be an excellent year for a full Mountain Bike Vacation, just take note that the Bike Park will not be fully up and running until the around the July 4th Holiday. 

>>> Just down the page, I have a detailed report on the local conditions and some ideas for where to mountain bike in the Eastern Sierra over the next ten days.

Mammoth Mountain & Eastern Sierra Recreational Weather Forecast

The forecast for this week into the Memorial Day weekend is looking great. Expect mostly clear days and about average temperatures for this time of year into Saturday. By Sunday and Monday, the next ridge of high pressure will be nudging into the area, bringing a warming trend for a week of warm Summer-like temperatures. 

Here is what you can expect for those planning on going on the hill today into Memorial Day.

Skies will be clear, with just a few clouds around the Sierra Crest from Bishop Creek Canyon up to Mammoth Mountain. Temperatures at the 9000-foot level (Main Lodge) will be in the low to mid-50s, with overnight lows in the low to mid-30s. By Sunday and Monday, daytime temperatures will be coming up around 5 degrees.

Winds on Mammoth Mountain and over the High Country will be SW into Sunday at 5-15 MPH, with gusts up to 20 – 30 MPH at times. Lower elevations winds from Crowley Lakes down to Bishop will be in the 5-10 MPH range. Afternoon winds in the Bishop area will be gusting 15-20 MPH at times. 

Temperatures for Mammoth Lakes will range from the low to mid-60s, with a bit of warming next Sunday into Monday. Toms Place to Crowley Lake, expect upper-60s to lower 70s with nighttime lows in the upper 30s to lower 40s. And for Bishop to Mill Pond, expect low—to mid-80s right into Sunday, with a high of 90 now expected on Memorial Day.

Eastern Sierra Mountain Bike Report – Where to Ride Today

>>Mountain Biking Disclaimer Alert<<

The Mammoth Mountain Bike Park is digging out from a cold, wet winter and spring. Starting this Friday, they plan to open with the Shot Gun Downhill Run and the lower 2/3 of Downtown. The Shuttle from the Village will be open and will drop people off just above the Chair 4 parking lot. Bike Park Tickets this weekend are $29, or you can pick up a season pass for $379.

Mammoth Lakes Mountain Biking: The melt off is complete below the 8,000-foot level, with patchy snow up to about 8,500 feet. Sherwin Creek Road is melted, plowed, and mostly dry. The back Meadow and Single-Track Trails off Sherwin Creek Road are wide open and in excellent condition.

When I checked a few days back, the Mammoth Rock Trail was ride able in the lower sections. With the warm days coming, it should be open top to bottom by the end of the month, if not sooner. You can also ride down the Mammoth Creek OHV road to the Mammoth Creek Crossing. Do note that the water is high, and you will have to ride back the way you came at this time.

When I checked last weekend, the Shady Rest & Saw Mill Road Area was melted out. Access to the Big and Little Smokey Loops is wide open and clear for Mountain Biking. However, these routes are very loose and sandy in many sections, so a class 1 E-bike is the call if you want to ride these loops.

(LRC) Lower Rock Creek Trail: All three sections are open, clear, and in prime spring shape. Watch for hikers, fishermen, and dogs along the trail. You can learn more about LRC at this link.

Wagon Wheel Trail off Lower Rock Creek Road is open and in great shape.

Sunny Slopes / Upper Gorge Loop is now ridable, but be aware that some roads on this route are starting to be a bit sandy. Be ready to power through. We need to get a crew together and clean up the road section leading up from the River to the upper sections of this ride. Tons of overgrowth make it almost impossible to ride at this time.

The Poleta Canyon OHV Area is located at the end of E Line St and has miles of open, ridable terrain. Poleta Ridge and Poleta Canyon Trail are open, as are all the OHV Roads and other unnamed single-track trails in that area. Last I heard, the Black Rock Mountain road was still a mess, but a crew from Valley Org will be cleaning the road up sometime soon.

White Mountain Road to the White Mountain Single-Track Trail is now open. Be aware that this area offers some very steep climbing in spots; if you plan to ride this area, you better be in mid-season shape or on a class 1 E-MTB. There are also several water crossings on the lower part of this route, so be ready for the water.

The Buttermilk Country and the Tungsten Hills are also melted out and ready for a great Spring ride. This is a great time to explore these areas as the weather is still not hot and perfect for riding and exploring the mix of OHV roads and off-the-cuff single-track trails you will find in this area.

Mill Pond to the Foothill areas of Western Bishop is in great shape as of this post, with miles of OHV roads and hidden single-track trails you can ride. Here is a link to the Google Maps for these areas. To find a place to park and ride on that map, zoom in, and you can see all sorts of open dirt roads. Many of these roads have single-track trails that break off from the road you can explore.

That map’s roads and trails are on BLM, DWP, and Forest Service Land. You can ride in these areas if they are not signed as closed.

On Forest Service roads that are closed, you can check with the Forest Service, as many times you can still ride a mountain bike or Class  1 peddle-assist E-MTB on those roads. I advise you never to ride by a road closed sign; check first, and don’t get ticketed.

The Footloose Bike Shop is now fully open for Bike and e-bike Rentals and Bike Repair Services. They also have mountain bike and road biking gear available for retail sales. Give them a call at 760-934-2400, and they can answer your questions.

Black Tie Adventure Rentals also carries E Bike, a 4 x 4 Truck and Kayaks and Rafts you can rent, use this link to access there rentals here in Mammoth Lakes.

Welcome to Eastern Sierra Mountain Biking

If you’re looking for a unique place to go for a Mountain Bike adventure, you must check out the Eastern Sierra Region.

There are countless opportunities to ride here, from Traditional Mountain Bikes to the new Mountain E-Bikes. You will find everything from single-track action to motocross trails, OHV trails, and forest service roads that lead deep into the back country.

This website is here so you will know where to ride, current trail conditions, and what to expect from the local weather on your next Mountain Bike Trip to the Eastern Sierra.

We cover most of what you can ride at the Mammoth Mountain Bike Park, in the Inyo National Forest, and in the Bishop and Big Pine areas. There are miles and miles of mountain biking to be had up here.

While you will find a lot to ride on this site, there are countless roads and off-shot single tracks that are not mapped or marked that you will discover as you investigate this area on your mountain bike.

During most years, there are only a few days when you can’t find a place to ride in the Eastern High Sierra and the Northern Owens Valley. If you’re into Mountain Biking, we hope to inspire you to come up and ride in the Eastern Sierra sometime soon. 

**This website is being built from 2023 into 2024; once we get all the content in, it will be an excellent resource for Mountain Bikers and E-MTB riders. Keep checking back for fresh ideas of where to ride.
