The Mount Fremont Lookout can be easily accessed from the Sunrise parking lot via Frozen Lake, but I came up from the White River Campground, Emmons Morain and Burroughs Mountain, then back to the campground on the Wonderland Trail. It was a full, spectacular day on the mountain. Most of the crowds come from Sunrise and either stop at Frozen Lake or continuing to Burroughs Mountain. Fewer people brave the incline to Mount Fremont. That's not to say that there weren't plenty of people there.
The two story fire lookout is one of four that remain in the park. The others are Shriner Peak, Tolmie Peak, and Gobbler's Knob. Mount Fremont at 7000 ft is the highest in the park. It was built in 1933. I just love hiking to fire lookouts because they represent such a definitive destination and offer a visual treat at the end of a hike.
The trail to the lookout isn't too strenuous. It's a 5.5 mile out & back from Sunrise and only 800 ft elevation gain. The views of the mountain from the trail aren't any better or worse than from the lookout itself. In other words, they are stellar regardless. Definitely put a visit to the lookout on your list.
