You may have seen my video from earlier this summer about hiking McCullough Gulch to the waterfall and lower lake! Well, there is actually a Lower McCullough Gulch trailhead! It is located off of highway 9 across The Lodge on the Blue. This is a great little hike if you want something short with some great views. When you reach the road you can connect to the Wheeler trail as well if you want more of a hike.
To get from the parking lot to the road it was about 1.2 miles and about 800 foot elevation gain.
