Exploring The Alpine Loop – ATV Colorado

ATV The Alpine Loop

  • Length: 65 mile loop
  • Drive Time: 6-7 hours
  • Difficulty: Overall Easy / Moderate In Sections (rock outcroppings, drop offs)
  • Access: Easy
  • ATV Friendly Town: Lake City
  • Ideal Riding Season: Mid Summer – September

Notes: The Alpine Loop can be done by SxS and ATVs.

Lake City has passed a pilot program to allow OHVs on a 3.26 mile stretch of Hwy 149. This pilot program is currently in effect “seasonally in 2021, 2022, and 2023, from the Friday before Memorial Day through September 30 of each year”.

I don’t feel confident that this will continue past 2023, but hopefully I’m wrong.

As of October 2021, Silverton changed it’s laws. OHVs are now banned within city limits. You can no longer easily ride out from town.

One of The Most Stunning Drives In The US

This ride should definitely be on your bucket list. Although not technically an “ATV trail”, this remote dirt road loop is open to ATVs/SUVs. It’s so amazing that we’ve included it in ATV Colorado: 10 Best ATV Trails In Colorado.

The Alpine Loop passes through the sweeping Rocky Mountains through two mountain passes – Engineer Pass and Cinnamon Pass, both 12,000+ feet high.

In between the mountain passes you’ll experience some of the most amazing views – mountains, meadows, waterfalls, lakes and wildlife.

This 63 mile dirt road loop takes you from Ouray or Silverton to Lake City.

This is a very popular dirt road – Jeeps, 4x4s and ATVs all use this road so don’t expect to have it all to yourself.

To avoid the big crowds go in late September when the kids are heading back to school and summer vacations are mostly over.

The speed limit is 15 miles an hour, so allow 5 – 7 hours for a leisurely ride. In addition to the Alpine Loop, there are also plenty of miles of other smaller ATV loops and detours connected to the main loop.

Plan for a couple nights in the area for a more relaxed ride with time to soak up the scenery and explore the history of Colorado.

Lake City is the only ATV friendly town on the loop. Ouray is not ATV friendly, it does not allow ATVs within the city limits.

Silverton used to be ATV friendly, but they changed the law on October 12th, 2021. Now, there is a ban on “OHVs on all streets, alleys, and rights-of-ways within town limits”.

Silverton is no longer ATV friendly.
