Jeeping Bunce School Road in Winter: Your Guide from Allenspark to the Seasonal Gate and Ironclads Loop

Looking for a winter off-road adventure near Estes Park? Bunce School Road (Forest Service Road 105) is one of Northern Colorado's best-kept secrets for cold-weather wheeling. This scenic route through the Roosevelt National Forest offers packed snow, pine-lined corridors, and just enough challenge to keep things interesting without putting your rig at serious risk.

Whether you're a seasoned off-roader or just getting started with winter trails, Bunce School Road delivers a rewarding experience with options for every skill level. The main road is approachable for most stock 4x4 vehicles, while the Ironclads Loop adds a more technical challenge for drivers looking to test their skills on rocky terrain and steeper obstacles.

In this guide, we'll walk you through the full route from the Allenspark staging area to the seasonal gate near Peaceful Valley, with a closer look at the Ironclads Loop and a brief introduction to the historic T-33 plane crash spur just beyond the gate.

Three Things to Know Before You Go

1. Beginner-Friendly Main Trail: The main stretch of Bunce School Road (FR 105) is rated easy to low-moderate and is suitable for most stock 4x4 vehicles with decent ground clearance. You don't need a heavily modified rig to enjoy this route.

2. Ironclads Adds Real Challenge: The Ironclads Loop on Forest Road 216 is a step up in difficulty, featuring ledges, loose rock, off-camber sections, and boulder fields. Four-wheel-drive low range is recommended, and a spotter can make a big difference on the trickier obstacles.

3. Seasonal Gate Limits Winter Access: A seasonal gate near Peaceful Valley closes off the southern portion of the trail during winter months, including the spur to the T-33 plane crash site. Plan to turn around at the gate and save the full through-route for summer.

Getting Started: The Bunce School Staging Area

Your adventure begins near the historic Bunce School on County Road 105, accessed from Highway 7 approximately 3.7 miles southeast of Allenspark. The county road quickly transitions into National Forest Service Road 105, and you'll find a small staging area just past the entrance that makes a convenient spot to air down before heading in.

Winter Tip: Dropping a few PSI from your tires before hitting the trail makes a noticeable difference in winter conditions. Lower pressure means more traction on packed snow and icy patches, a more comfortable ride over rocky sections, and less chatter through your steering wheel. It's a small adjustment that pays off immediately.

A Quick History of Bunce School

The road takes its name from the Bunce School, a one-room log schoolhouse built in 1888 by V.H. Rowley and J.H. Bunce. This small 25-by-17-foot structure served the local mountain community and was listed on the National Register of Historic Places in 1986. It's believed to be the only surviving log schoolhouse in Boulder County, making it a genuine piece of Colorado mountain history you can see right at the trailhead.

The Main Trail: FR 105 from Allenspark to the Seasonal Gate

Once past the staging area, the road settles into a mix of packed dirt and snow as it winds through stands of pine and small aspen pockets. In winter, shaded sections will hold packed snow and ice, so steady speeds and smooth inputs are your best friends.

This is a mixed-use trail, so expect to encounter hikers on warmer days, motorcycles, and even side-by-sides sharing the road. Trail etiquette matters here: always yield to uphill traffic when you meet someone coming the other way, keep speeds down near private inholdings along the route, stay on signed routes, and pack out whatever you pack in. These simple practices help keep trail access open for everyone.

The main road features one section where line choice really matters, with embedded rock and tighter turns. In snowy conditions, the approach is crawl in place rather than gas and hope. Let the tires do the work, keep your momentum controlled, and look where you want the tire to go.

The trail ends at a seasonal gate near Peaceful Valley. During winter months, this gate marks your turnaround point. When the gate opens in summer (typically sometime between May and June, depending on conditions), you can continue through to Peaceful Valley and connect with the Peak to Peak Highway (Colorado Highway 72).

The Ironclads Loop: A Short Loop with Big Features

Shortly after entering FR 105, you'll reach a Y intersection where Forest Road 216 branches off to the right. This is the entrance to the Ironclads, a rocky loop trail that delivers a noticeably more technical experience than the main road. The Ironclads sit within the Roosevelt National Forest and are officially designated as Forest Road 216 (with the loop section on 216A).

What makes the Ironclads worth the detour? This loop packs a lot of variety into a compact distance. You'll encounter rock outcroppings, boulder fields, ledges that require careful line selection, loose rock climbs and descents, tight off-camber turns, and a few steep sections that will test your vehicle's clearance and your ability to pick the right line. There are also dispersed camping spots and rock gardens along the way if you want to stop and play.

Driving Tips for the Ironclads: Four-wheel-drive low range is the right call here, especially in winter with snow adding an extra layer of challenge. Most drivers run the loop clockwise, which means climbing up through the more significant obstacles first. The key technique is controlled crawling: breathe, look where you want the tire to go, and let the Jeep's idle do the work. Momentum isn't a mod on this trail. Slow, deliberate tire placement will get you through obstacles that speed and throttle won't.

The Ironclads are an excellent place to practice line selection and tire placement skills in a setting where the consequences of a mistake are manageable. There are no shelf roads or dangerous drop-offs, so you can push your comfort zone without putting yourself or your vehicle in a truly precarious situation. That said, a spotter is always a good idea, and longer wheelbase vehicles may find some of the tighter sections more challenging.

The T-33 Plane Crash Spur: History in the Mountains

Just beyond the seasonal gate lies the spur trail (Forest Road 203) leading to one of Northern Colorado's most compelling historical landmarks: the wreckage of a U.S. Air Force T-33 trainer jet.

On June 27, 1965, USAF Major Jay E. Currie and 1st Lieutenant Donald B. Darby were flying a Lockheed T-33 trainer jet when their aircraft veered off course and crashed into the mountainside in the Roosevelt National Forest. Both crew members, who were instructors with the Edwards Aerospace Research Pilot School in California, lost their lives in the crash.

Today, significant wreckage from the aircraft remains scattered across the mountainside, serving as a quiet memorial. A sign at the site provides brief details about the crash and the airmen who perished. The spur trail to the crash site is rated more difficult than the main Bunce School Road, with large embedded boulders and rocky obstacles that challenge even experienced drivers.

Important Note: Because the seasonal gate blocks access during winter, the T-33 spur is a summer destination. If visiting, please treat the crash site with the respect it deserves as a place where two servicemen lost their lives. Stay tuned to our channel because we plan to return in summer to drive the full route through to Peaceful Valley and visit the crash site.

Winter Wheeling Tips for Bunce School Road

Bunce School Road is a popular year-round destination, but winter brings unique conditions that are worth preparing for. Here are some practical tips to make your cold-weather run safe and enjoyable:

•       Air down at the staging area. Dropping tire pressure improves traction, comfort, and control on packed snow and rocky terrain. Just remember to air back up before hitting the highway.

•       Crawl, don't charge. In snow and ice, slow and steady tire placement beats momentum every time. Let your vehicle's low-range gearing do the work.

•       Watch for shaded sections. Ice and packed snow linger in shaded areas well into spring. Approach these spots with extra caution.

•       Yield to uphill traffic. Standard trail etiquette applies year-round. If you meet someone coming up, give them the right of way.

•       Stay on signed routes and pack out your trash. Responsible use keeps these trails open for the entire off-road community.

•       Check conditions before you go. Snow depth and trail conditions can change quickly. The USFS Arapaho and Roosevelt National Forests website posts current conditions and seasonal closure updates.
