More of a walk than a hike and was fairly busy. It's an easy one but with some great highlights. The trail is kind of hard to follow exactly because there's so many well worn off shooting paths. Try and stay on trail as much as you can to get to the Grottos/ice caves. From there, keep going straight, cross the bridge, then stay slightly left/straight (don't go right) to reach the Cascades (very pretty waterfall that has multiple pools and levels). It's such a short, easy hike that you're unlikely to get lost if you follow the numerous trails, it just makes it more time consuming to find the sights you're there for.
Would definitely recommend going early because the parking lot gets kind of full. Plus, it will be less crowded earlier in the day.
