Eastern Sierra Mountain Biking Report & Information Guide

Thursday, June 13th @ 8 AM – Happy Summer Time to all the local and traveling Mountain Bike Crowd. As of this update, most mountain biking trails and OHV roads below the 9000-foot level are ready to ride from Mammoth Lakes down to Bishop.

Above that level, you will still find snow on the ground in many areas, over the next couple weeks most of that snow should melt off and you should be able to ride up to 11,000 feet.

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 but take note that the Bike Park will not be fully up and running until late June this year.

>>> 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

Here is what you can expect in the High Country into Monday: Above-average temperatures will continue today as a ridge of high pressure continues to make its presence known. This looks to be the last day for the 20-30% chance of thunderstorms, and then the area will dry by Monday. 

At this time, the ridge is quickly moving towards the east, which will lower the heights and bring in a bit of cooling on Friday. Further cooling is expected over the weekend into next Tuesday as a deep low drops in the western Great Basin.

Mid-day temperatures at the 9000-foot level (Main Lodge / Lake Mary) will be in the low 70s, with overnight lows in the low 50s. Over the weekend, expect mid-day highs to drop into the mid-60s, with mid-50s expected by Monday. Winds on Mammoth Mountain and over the higher elevations will be SW at 5-15 MPH, with gusts up to 20-25 MPH at times.

Temperatures for Mammoth Lakes will be in the lower 80s, with nighttime lows in the low to mid-50s. By Friday and into the weekend, you can expect 3-6 degrees of cooling. Winds will be out of the SW at 5 – 10 MPH, with gusts to 20 MPH at times. Mid-day temperatures from Crowley Lake to Toms Place will be in the mid-80s, with nighttime lows in the upper 40s to lower 50s. Midday temperatures over the weekend will drop into the low 80s.

For Bishop to Mill Pond, Summer is on, with perfect mornings in the 70s and 80s and then upper 90s expected by mid-day into Saturday. Temperatures will cool off big time by Sunday into next Tuesday.

Eastern Sierra Mountain Bike Report – Where to Ride Today

>>Mountain Biking Disclaimer Alert<<

The Mammoth Mountain Bike Park: This week’s warm temperatures are speeding up the snow melt-off. As of this update, crews have got Shot Gun and Smooth Operator all dug out and open. Gopher Trail, lower Paper Route, Timber Ridge, and Juniper are now open. Uptown and Downtown are also now open top to bottom as crews cleaned up the top sections over the last week.

Uptown and Downtown are also now open from top to bottom, as crews cleaned up the top sections over the last week. On Friday, they plan to open three trails in Discovery Park for some perfect park practice action.

Starting next week, the Snowman will have regular updates right from the Bike Park with fresh photos and trail videos.

Mammoth Lakes Mountain Biking: This week, there are places to Mountain Bike in the Mammoth Area. Try the Connector Trails off of Sherwin Creek Road or Mammoth Rock Trail. Uptown and Downtown are open, with Free Access to Mountain View Trail. The MVT is mainly melted out, but as of last weekend, there were still some snow patches in the shade in the upper sections.

Sawmill Road out of the Shady Rest area is open so you can access the Big and Little Smokey Bear Loop Rides on the east side of 395. With the loose dirt on these two trails, I advise using an E-MTB. When I take my peddle bike out here, it’s just too loose and sandy in spots to have much fun.

(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 ridable, but only during the early morning hours as the Summer heat bakes 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.

The roads and trails on that map are on BLM, DWP, and Forest Service Land. If they are not signed as closed, you can ride in them.

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 Ski & Bike Rental also carries a Trex E-bikes, and Town Cruisers. Use this link to access their 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.
