No, this is in Rocky Mountain National Park, so it's paved all the way to the parking at the trailhead. Any vehicle will work unless it's winter. You need a pass and a timed entry to get into the park, which you can get at the RMNP website. The hike is approximately 5.5 miles roundtrip from the trailhead.

First and only time I visited this spot, I hiked around to the left in the photo to where I could see the entire lake. I stayed there for probably 15 minutes and saw a cow elk and her calf swim across the far side of the lake. It felt like there wasn't a human within a million miles of that spot and was one of the most peaceful moments of my life.
