We drove into the park, paid 8$ at the entrance. There was a public restroom in the first area of parking spaces. the restrooms were typical hole in the ground type that I see at most trails, and I don't love it. the park itself is amazing! In the beginning of the park, as we drove in, we could see a few groups of climbers coming up the side of the walls of the mountains on the lefthand side. And on the right side, was a bridge and the whale tail rock, and these led to two trails going in opposite directions and in between that was a sign that said expert trail which pointed up and looked scary! We explored around both non expert trails and while the one to the left just kept going further up, the other led down to the water and along the little body of flowing water. We decided to drive further into the park and found a nice pool with larger rocks and some sand. it was pretty amazing and was so peaceful. We saw the South Boulder Mountain and a couple others which were all so beautiful and photos just cant do it justice. Next time I will be more prepared so I can try to make the hike to the main waterfall. All in all, I had an amazing time! I feel really silly that I have lived in Boulder for 2 years and not come here until now.
