Winter fat biking: where it's allowed
Grooming and winter rules belong to each land manager. These are their published rules, summarized:
| Chugach State Park | Fat bikes (3.7 in+ tires, under 20 psi) may ride any trail open to bikes, plus Middle Fork Loop, Lost Cabin Valley, the Eagle River Water Trail to Icicle Creek, and frozen Eklutna Lake, from Nov 15 to Mar 31. Alaska State Parks: Chugach State Park recreation (bike rules, 11 AAC 20.050) |
|---|---|
| BLM Campbell Tract | Winter fat biking is allowed. Winter-only singletrack needs frozen ground and about 6 in of snow. Stay off mushing-only trails. BLM: Campbell Tract |
| Government Peak (Mat-Su) | Fat bikes ride the singletrack. Pioneer Loop is the only groomed trail that allows fat bikes. Mat-Su Borough: Government Peak Recreation Area |
| Kincaid Park | Nordic ski trails are closed to bikes in winter. Cross only at designated crossings. Anchorage Parks & Rec: Kincaid singletrack map (PDF) |
| Birch Hill (Fairbanks) | Cycling is prohibited on the winter ski trails. Fairbanks North Star Borough: Birch Hill trail map (PDF) |
Gear that works up here
Fat-bike pogies and layers
Real winter riding at −10 °F needs pogies over the bars and boots you can walk in. See our backcountry and fire-camp kits for the layers.
Bear spray on the bike
Carry it in a holster on the frame or hip belt, not in the pack. Our kits list proven canisters.
Ride, then ski
The same small builders and shops cover winter. Splitboards, touring skis and Alaska tune shops are on our skis page.
Not listed, and why
- Lost Lake and Primrose (Seward): USFS lists both as hiking trails, with no biking activity. We couldn't confirm bike use on the official pages, so they aren't listed here.
- Hatcher Pass: We found no official mountain bike trail at Hatcher Pass, and Skeetawk's summer trail page doesn't mention bikes. The Gold Mint and road rides on Singletracks are unofficial listings.
