The water on the upstream side runs through an old lava tube. I'm told (but haven't seen myself) that when the water isn't too rough, you can carefully hike upstream through the tube to see two waterfalls. There's good parking for several cars just past the bridge in the direction away from Hilo (towards Pepeekeo).

Akaka Falls State Park is located on the northeastern Hilo Coast and features two magnificent waterfalls. The 0.6 km long, gently ascending hiking trail takes you through a lush rainforest with wild orchids, bamboo groves and hanging ferns. If you continue following the paved footpath, you will first come across the 30 m high Kahuna Falls. Behind the next bend in the circular route you can already see the towering Akaka Falls, which plunge over 135 m into a gorge. The beautiful waterfall is probably the most famous of its kind on Hawaii Island. The pleasant hike takes less than an hour. https://www.gohawaii.com/de/islands/hawaii-big-island/regions/hilo/akaka-falls-state-park

Kolekole Beach Park is a nice area where the Kolekole Stream meets the ocean. There is a small waterfall, a nice beach, and a large grassy area, which makes it easy for families to gather, which makes it very popular during the weekdays and holidays. The park is currently temporarily closed due to some soil contaminants. Because of the closure, the park is not currently well maintained and has become overgrown. The ocean conditions here are a little too dangerous for swimming, but visitors can swim in the Kolekole Stream. There is no lifeguard here, so visitors should always visit and swim with caution.
