On the easy side of moderate, with only 600 ft elevation gain over 3.2 miles, this trail is accessible to most visitors of Rocky Mountain National Park. While the views on this trail are breathtaking at any time of the year, there is something special about experiencing the stark wintry conditions as you pass through several iconic landscapes.
One of the most popular mountains to hike in Boulder is Mt. Sanitas. Strenuous, but short, with about 1,250 ft elevation gain over 1 mile uphill, it’s a great option for those who want some solid exercise in a short period of time, while also taking in some beautiful views of the surrounding mountains and Boulder. If you’re training for a big hike, ascending Mt. Sanitas twice is a way to get in extra elevation gain and mileage.
Green Mountain is the third highest mountain in Boulder at 8,150 ft, and one of the 5 iconic mountain peaks in Boulder. Whether you just want to see the excellent views, or to get some serious exercise, or to train for a high elevation gain hike, the Green Mountain Loop has it all. Beyond the exercise aspect, I love how this hike showcases different types of scenery along the way.
The 7.3-mile option of hiking Mt. Sanitas via Sunshine Canyon and Lion’s Lair Trails out-and-back is now one of my favorite hikes in Boulder. You get the elevation gain of hiking Mt. Sanitas, while also getting to enjoy the beautiful views of Lion’s Lair Trail, and some good hiking mileage to boot.
