Eastern Sierra / Mammoth Lakes Mountain Bike Report

July 15th, 2026 @ 10 AM – Mountain Biking season is in full swing in Mammoth Lakes and across the Eastern Sierra.

The region even picked up some rain on Monday and a few light showers yesterday. The mountain is reporting .22 inches of rain from Monday at the 9,000-foot level by Main Lodge. Trails rode nicely on Tuesday with the added moisture; hopefully, we see more rain soon. 

All USFS Single Tracks and Service Roads are open at this time for a mountain bike ride. The only area still closed is the east bowl at Mammoth Mountain due to the Forest Service’s thinning of trees in the area. This is a hard closure that hopefully gets lifted in the next week or two. 

Eastern Sierra Weather Forecast: Over the next 2-3 days, expect mostly clear skies with temperatures at the 9,000-foot level in the lower 70s with winds @ 10 – 25 mph at times.

By the weekend into early next week, there will be a 20-30% chance of afternoon and evening thunderstorms in the high country.

Mammoth Lakes will be in the upper 70’s to lower 80s with overnight lows in the mid 50s. For Mill Pond to Bishop temps afternoon and evenin temps will be in the mid to upper 90s through the weekend.

USFS Trail Conditions and recommended rides:  Many areas have been a bit dusty as it’s been warm and dry for the last few weeks. The rain we just got was not much and will be out of play in the next day or two. 

Inyo Craters and the Smokey Loops are getting a bit loose. I would only ride them on an EMTB, so you don’t bog out and hate your ride. Yes, these routes allow E MTB class 1 E Bikes since they are old OHV trails.

Mammoth Rock Trail, Mountain View via the Uptown Trail free access section, and all the little extra trails out in Shady Rest are game on with a mix of firm pack to loose dirt. These trails are all peddle only. Also open is the Knolls Loop, which is essentially just old OHV and service roads, so you can ride an E MTB bike.

If you want to ride in the Bishop area, do it early, before the summer sun bakes you out. It’s too hot to ride after around 10 AM. And please, NO dogs in the lower lands on rides right now, it’s just too hot.

Mountain Bike Park Report: Most of the bike park is open as of today, 7-15.

Trails not open are in the east bowl area of the ski area by chairs 15, 25, 9, and 8. The forest service is Thinning Trees in the area, and their new finish date is now TBA or unknown.

The good news is that there are tons of trails to ride in the Canyon Lodge and Main Lodge Areas. The top is open minus Skid Marks, so you have access to Off the Top and the Eliminator and all the trails you can access off those two. 

Cross Country Riders, Beach Cruiser, Bearing Straight, and Gravy Train are now open, as is Mountain View outside of the park. 

Chair 4 will be running Friday – Sunday’s this Summer. Trails expected to be open off the top of 4 will be Brake Through, Flow, Boomerang, Seven Bridges, and Richter. Follow Me and Bullet will be closed due to Forest Service workers near those trails.

Also open is Chair 11, with all the fun Discovery Park Trails for newbies and kids.

O and don’t forget the Bike Park Shuttle that runs out of the Village will be open.

Lifts: Gondola 1 to Mc Coy Station, Discovery Chair, Bike Park Shuttle, Chair 4 runs Friday – Sundays 10 AM to 3 PM
