My husband is more of a hard core hiker and did a bit more hiking at Custer State Park when we were there earlier this summer. But for me Cathedral Spires was an easy and enjoyable hike that I think most people will like. The key is start early in the morning to avoid the scorching sun and the frequent afternoon thunderstorms. If you’re looking for some challenging hikes, consider Little Devil’s Spur and/or Black Elk Peak. My husband did that one on his own. It’s the highest spot in South Dakota (7242 feet).
Cathedral Spires is roughly 1.6 miles out and back. It takes you to the base of the spires and if you’re lucky you might spot some climbers like we did. It’s a moderate uphill climb and there were quite a few mosquitoes in the first half mile or so as we crossed some marshy meadows filled with wildflowers
