This is a really short hike outside of the Woodland Park area that leads to some really cool Red Rock formations which are full of caves, and different places to climb.
In Woodland Park driving on HWY 24 towards Divide, you will see signs for HWY 67 which is where you'll need to get to. The Road will fork towards the end of town (left being 24 towards Divide, Right being 67). Stay right at the fork onto 67. You will then drive about 2 miles until you see a sign that says Red Rocks Campground, and Pikes National Forest. You will take a right into the park, drive for about 1/4 mile, until you reach the power lines overhead. There isn't really a clear trail marker for where the trail starts, other than those power lines. You can park right there and follow the power lines for 1/10 of a mile and you will arrive at the first set of Rocks. There are a few different sets of rocks that go on through the park too, so theres plenty to explore!
Once you hit the rocks, there are all kinds of nooks and cranny's for you to explore, none of which are super difficult. The top does have some great views of distant mountains and is appropriate for kids and all skill levels.
