Where is Berthoud Pass located, and why might this drive be challenging?

Berthoud Pass is situated between Winter Park and Berthoud Falls and takes you high in the Rocky Mountains on the Continental Divide. The route itself is named after Edward Berthoud, the chief surveyor of the Colorado Central Railroad back in the 19th century, and is open all year round, weather permitting of course.

Berthoud Pass reaches an elevation of over 11,307 feet and for those who don't like driving at altitude, it can be a nervewracking experience. Not only because of the nature of the drive, but altitude sickness occurs at 8,000 feet or above, so the elevation can lead to sickness or discomfort.

At such a high altitude, the pass is subject to severe weather conditions. In winter, heavy snowfall and ice on the roads make it a dangerous proposition, although the road is regularly plowed.

The area is also prone to avalanches in winter. Even during the summer months, the weather can change quickly making driving conditions difficult.

The roads leading to and from Berthoud Pass have sharp switchbacks and are steep, although the exposure isn't as severe as other mountain passes. The winding switchbacks can be tight in places but there are guard rails in place so it's not as daunting as many may imagine.

Skiers and snowboarders descend on the area in winter, with around 65 advanced slopes to enjoy, and you'll find them on the road looking for a lift back to the top. Likewise, in summer, the area is popular with hikers keen to explore this pristine wilderness and it's important to look out for them if they are walking on the road.

Driving through Berthoud Pass

A good starting point for a drive through Berthoud Pass is Winter Park, a top ski resort in winter and popular year-round for outdoor activities.

The route begins by heading south and joining US-40 E passing Iron Horse Resort and before crossing Fraser River towards Midland Campground. After a further 4 miles, the fun begins as you head past Robbers Roost Campground before the sharp switchbacks begin as you head towards Second Creek Trailhead.

The route continues its winding ascent, crossing Current Creek before a series of bends lead you to Berthoud Pass. There is a parking lot at the top, giving you the perfect opportunity to stretch your legs and and marvel at the views, across to Colorado Mines Peak to the east, and the incredible wilderness in every direction.

Back on the road, the route sweeps through a series of impressive switchbacks before arriving at Berthoud Falls Cascades. Here you can take the nearby trail and hike to the falls, taking in the glorious views over the Rocky Mountains. The route then continues west before arriving in Berthoud Falls.

Things to know that can impact the drive through Berthoud Pass

While a drive through Berthoud Pass is an exhilarating experience, there are a few things to keep in mind that can impact the drive.

The drive itself is relatively straightforward along Highway US-40 and the roads are generally well maintained, although do keep your eye out for potholes. The last thing you need is a puncture at such an altitude.

The route is generally 2 lanes, 1 in each direction, but on some of the steeper sections, there is an additional lane to allow you to pass slower-moving vehicles. Do be mindful of the speed limits, which vary along the way.

On straight sections, the limit is 45 MPH but this reduces to 35 MPH on some of the bends, and even 15 MPH on some of the sharpest switchbacks.

The weather can have a serious impact on your journey, especially in winter when the road is likely to be covered in snow and ice. The road is regularly plowed, but conditions can still be treacherous.

Passenger vehicles are required by law to have mud or snow tires fitted and have the use of chains available. The route is an avalanche risk so always check conditions before making the journey and be prepared to postpone your trip if necessary.

Traffic can make a journey through Berthoud Pass slower, especially at weekends and during the holiday season. Traveling outside of these periods means there will be less chance of delays and more parking available at the viewpoints.

There are few rest stops and services along the route so consider stopping at Fraser or Georgetown enroute. They are also handy places to fill up with gas before heading for the Pass.

Cellphone coverage can be weak or non-existent in places, given the location, so while the route is quite straightforward, you can't always rely on your phone for directions or travel information.

Tips to drive through Berthoud Pass in the safest way

A drive along Berthoud Pass is a memorable journey and driven safely and sensibly, there is no need for it to be a dangerous experience. Here are a few of our top tips to help you enjoy this wonderful route even more:

• Avoid traveling at night with reduced visibility.
• Avoid weekends to reduce the chance of traffic congestion.
• Check for road closures before setting off.
• If you're hiring a car, request one with winter tires or chains, especially in winter, and ensure you have your own if driving your own vehicle.
• Make sure you have adequate fuel for your journey. Fuel up at Winter Park or Idaho Springs if coming from Denver to avoid running low.
• Do not drive in heavy snow storms or blizzards. Consider staying in Winter Park or Fraser.
• Monitor the weather and use sources like the Colorado Department of Transportation (CDOT) and the National Weather Service (NWS).
• Do a “virtual drive” using Google Street View so that you can prepare yourself and “see” the route for yourself beforehand.
• If possible, have two designated drivers to share the load so you can stay fresh.
