Great hike! Lots of stairs and rock scrambling to get to the top but the views are worth it! We took the route to the North Bubble and there are several overlooks along the way. The trail is mostly shaded but I still recommend packing water, sunscreen, and a hat. Bring a snack to enjoy at the top! I saw a lot of people without any supplies on them. Could be up to a 4 mile hike if you continue to the South Bubble. The parking lot is small.
