Great 0.7 mile hike in the Rocky Mountain National Park. You will need a timed entry pass to get in. We reccommend getting that a month prior to your hike. Passes into the national park are $30 a car and timed entry is $2, but they sell out quick on the timed entries.
Great 0.8 mile hike in RMNP. This also requires the Bear Lake timed entry pass.
