Reaching our location on Highway 91 means driving mountain roads in winter conditions. If you're coming from the Denver area, our snowmobiling near Denver article covers the best routes and timing. Here's what you need to know to arrive safely.
Colorado Traction Law
Colorado's traction law can be activated on I-70 and mountain roads:
- Requires adequate tires OR chains/alternative device
- Adequate means: M+S rated, all-weather, winter tires
- AWD/4WD doesn't exempt you - tires matter
- Fines for non-compliance during activation
Recommended Vehicle Setup
- AWD or 4WD highly recommended
- Winter or all-season M+S tires
- Carry chains even if you have AWD
- Check tire tread depth before travel
Check Conditions Before You Leave
Mountain weather changes fast at altitude. Our weather and conditions page covers what to expect throughout the season. Resources to consult:
- CDOT: cotrip.org for road conditions

I-70 specifics
Interstate 70 from Denver into the mountains is the most-used highway in our area and presents specific winter challenges: traction laws activate when conditions deteriorate, mountain passes (Floyd Hill, Eisenhower Tunnel approach, Vail Pass) often have separate weather patterns from the surrounding valleys, and weekend traffic compounds delays. Check CDOT alerts and the COtrip.org website before leaving Denver, and budget 30-50% extra travel time during stormy weather.
Tire and equipment basics
Colorado’s traction law requires either snow tires, all-season tires with the M+S rating, or chains for passenger vehicles when activated. Most rental cars from DEN come with all-season tires that meet the requirement, but verify before heading into the mountains. AWD or 4WD vehicles handle storm conditions noticeably better than 2WD, especially on the climbs from Frisco to our staging area on Highway 91. Carry an emergency kit (blanket, water, snacks, flashlight, basic first aid) anytime you drive in the mountains during winter — even a brief unexpected delay can become a serious problem if you’re unprepared for cold.
