A Trail Less Traveled: Hollowell Park to Mill Creek Basin in Rocky Mountain National Park

It’s official – we have been away from Rocky Mountain National Park for far too long! But the count-down is on because we reserved our cabin for a trip at the end of May. In anticipation, I’ve been taking a look back through our family’s hiking journal and came across a hike that I haven’t shared before.

Hollowell Park

Back in May of 2016, we ventured to Hollowell Park because it was an area in RMNP that we had never explored. We hoped it would be a good place to hike with our toddler during the spring season when some higher altitude hikes are still covered in ice and snow. The Hollowell Park turnoff is approximately 8,300 ft in elevation according to the park’s website. In comparison, Bear Lake is 9,475 ft.

I took a picture of the sign at Hollowell Park to give myself a visual of all the destinations you can hike to including Cub Lake, Bierstadt Lake, and Bear Lake. Hiking from Hollowell Park is not the most direct route to these popular attractions, but it could be a good alternate route to avoid some of the crowds during peak visitor season.

Mill Creek Basin

We decided to hike to Mill Creek Basin, which is a less popular destination in the park. Our hike was 1.9 miles each way which began in an open grassy area and climbed an additional 600 feet of elevation through towering pines.

The trail followed a mountain stream called Mill Creek. Several snowy patches remained on the trail along with muddy portions caused by recent snow melt. We crossed over a small wooden bridge to get to the Mill Creek Basin, a meadow with aspens which I imagine are even more beautiful in autumn.

Spring Hiking in RMNP

Spring can be a tricky season to visit Rocky Mountain National Park because the weather varies day-to-day. Here are some additional lower elevation hikes you might consider:

Best Hikes Under 5 Miles

The hike to Mill Creek Basin was just under 4 miles round trip. When we plan hikes for our young family, we typically aim for hikes that are similar in length. We broke down some of our favorite family-friendly ‘short hikes’ with details to help plan your adventure in the pages linked below:
