November 12, 2023, Lefthand Trailhead

The Lefthand Trailhead is the main access point for a popular system of mountain biking trails on the eastern end of Lefthand Canyon. More of a large pullout than a true trailhead with a parking lot, there are no bathrooms, picnic area, or water stations here. There are restroom facilities just a little down the road east of here at Buckingham Park if you need them.

The Ward General Store is a welcome sight for all cyclists after the hard climbing necessary to get here! Well-known and well-loved, the Ward General Store has snacks, drinks, and bathrooms for a quick refuel before tackling either more hard climbing or fast and long descents.

This section of the popular Lefthand Canyon is a long, but scenic climb with increasingly good views of the often-snowcapped Indian Peaks the closer you get to Ward. Ward is a tiny mountain town just off the Peak to Peak highway with a cyclist-friendly general store. This section is also super, super fun to fly down, but be aware deer in the road and cars.

As Niwot turns into Neva Road, you get fantastic views of Haystack Mountain to the east, a small, but prominent hill that resembles a rounded haystack, and of the foothills to the west. You are surrounded by picturesque farms, and on the Haystack side in particular, there are frequently very cute cows out grazing.

The Jamestown Mercantile is a cute, cyclist-friendly cafe in a historic building. There is outside seating both right out front and across the road in the park. They have an expansive menu (https://www.jamestownmercantile.com/menu) and live music and events in the warmer months.
