Moffat Tunnel West Portal

Experience the Moffat Tunnel West Portal

The Moffat Tunnel West Portal is one of Winter Park's most important historic landmarks. Located at the base of Winter Park Resort, the western entrance to the 6.2-mile tunnel has connected Colorado's Front Range and Western Slope since 1928 and remains an active rail corridor today.

For visitors, the Moffat Tunnel offers more than a piece of railroad history. The construction of the tunnel helped shape the development of Winter Park itself, making the Fraser Valley more accessible and laying the foundation for the mountain community and ski destination visitors know today.

The West Portal is easy to appreciate as part of a day at Winter Park Resort. Its location near the resort base connects visitors to a defining chapter of Colorado engineering, transportation, and skiing history.

Why Visitors Visit the Moffat Tunnel West Portal in Winter Park, CO

The Moffat Tunnel West Portal appeals to visitors interested in Colorado history, railroads, engineering, and the story behind Winter Park's development. The tunnel remains an active and highly visible part of the area's identity nearly a century after it opened.

Why visit the Moffat Tunnel West Portal:

• See a historic entrance to one of Colorado's most significant engineering projects

• Learn how the tunnel helped transform access across the Continental Divide

• Explore the connection between the railroad and the early development of Winter Park

• Experience a landmark located directly at the base of Winter Park Resort

• Appreciate an active rail corridor that continues to carry passenger and freight trains

The tunnel is named for David H. Moffat, the Denver railroad pioneer whose vision for a more reliable route through the mountains eventually led to its construction. Before the tunnel opened, rail travel crossed the Continental Divide over Rollins Pass, a difficult route known for steep grades and severe winter conditions.

What Makes the Moffat Tunnel West Portal Experience Unique

What makes the West Portal particularly interesting is its direct connection to the history of Winter Park. The community originally developed around the construction of the tunnel, and the area was once known simply as West Portal.

When the Moffat Tunnel opened in 1928, it created a more reliable route through the Continental Divide and improved access to the Fraser Valley. Skiers soon began arriving by train to explore the surrounding mountains, helping establish the area's reputation as a winter recreation destination. The railroad connection played an important role in the eventual development of Winter Park Resort, which opened in 1940.

Today, the tunnel continues to carry rail traffic beneath the Continental Divide. Amtrak's California Zephyr travels through the Moffat Tunnel, along with freight trains using the historic route.
