At a good pace, it took us 1 hour to get to the Monument. You will be in over grown jungle type trails and many types of lava rock with no shade. We encountered wild goats. The hike back is the hard part. We had a time limit and has to push hard up the trail. 3 bottles of water and soaked in sweat it took us 1.5 hours to get up. We are in fairly good shape aa we walk 3-5 miles 3 times a week. Well worth it but allow more time then we did. Can't wait to return better prepared!

Beautiful, short, relatively steep trail to the bottom. Slippery at the start, but 1/2 way down there were enough rocks & boulders to assist.

The beach was serene. Not a soul around which made it very peaceful.

Spectacular views! We did this in the light rain and it was muddy and slippery. Would not have been worth it in heavier rain, but as it was, we loved it. Some folks we passed found it easier to do with a walking stick. Given the mud, I thought the way down was much harder than the way up.

Nice solid hike. Sweeping views in some places

Not a hike but a very pretty view. Great place for someone who wants to see a beautiful waterfall but has mobility concerns.

not much of a trail, homeless in the brush to the south..... the small beach has amazing waves for surfing.

A nice paved loop in the National Historic Site. The history of this spot is rather interesting.

The falls area beautiful, not a lot of water flowing on the day we went. Would enjoy seeing it again when the flow is higher.

A fun stop while in the Hilo area. The lava tube cave is very interesting.

We headed West downhill from the trailhead until the road, which is about a 500' drop; the ferns are amazing - Jurassic style! If you continue clockwise up the roads, you go back up around 750' in elevation. Then you return on the above-described trail, dropping back down to the trailhead. I would describe that as a 2.3 mile medium difficulty hike.

Was very nice to swim once down. Coming back up was hard for me but worth it

Great views, of black sand beach and lush green valley. Easy trail with about six switchbacks down to the beach, can be slippery or muddy when wet ~20min down ~25min back

The bay and snorkeling are worth the hike down. Today the heat on the way back up was brutal, we had plenty of water and it was a hard climb out after snorkeling and enjoying the water, we hike regularly in Oregon at higher elevations with no issues. Be prepared and if you’re questioning your abilities I would recommend a boat tour over the hike.

cool short walk with a nice payoff recommend not wearing sandals tennis shoes okay

Mountain goats were a huge surprise—saw maybe two dozen of them. Once at the water, I set my pack down to go for a swim and had to come back because a Mongoose was going inside my backpack. About a dozen Mongoose showed up, so I had to hang my pack from a branch. Saw some amazing yellow fish playing in the water around Captain Cooks death memorial stone. Beautiful small finch like bird with a red head was super curious about my trail food. A little strenuous going back up, but we got hit with a monsoon like downpour which was a morale boost. Loved the trail—one of
My favorite hikes of all time. Watch out for boars too. We definitely heard them around near the upper portion of the trail in the thick grass.

Super overgrown at top of trail. Wouldn’t recommend for someone out of shape since the hike back is a strenuous one. Solid hike though and the bay is worth it.

Nice nature trail! Needed 1 hr each way

Wow. Just wow. Worth it to keep hiking up the mountain past the beach

This was an amazing trail with the most amazing views! The hike starts in a tropical like jungle, descends through a lava field, back into the woods, and then finally you arrive at the prize! Turn left at marker 8 to find the monument and snorkel bay. Warning: The grass gets extremely thick and overgrown at times. I recommend wearing a long sleeve shirt to protect your arms. My daughter got cut in the face and neck by the blades. But this was only for maybe 1/3 of the trip. If you have hiking boots, bring them. I promise you will be glad you did. Lastly, PLEASE bring enough water to last both ways. I wouldnt dare try this hike after 7am. The hike back up in the October sun was brutal.

This is not a hike but it is a pretty Falls. You cannot get down to the actual water. There are rails to prevent that.

Amazing experience.

Okay falls, no hiking allowed

Very interesting to see this lava tube as it is free of charge compared to other lava tube visits that charge $25 pp. We believe this was sufficient to explore a lava tube and we went all the way to the far end which was interesting.

Great trail, bring a lot of water, like a lot of water. Easy to go down, super hard to go up.

Trail closed as of 9/25 for mud slide.

This trail is cool if you want to access to a nice snorckelling spot, first part in the forest and second part in the stones decor with nice view on the ocean, if you go at 17:00-18:00 you can see a wonderdul sunset !!

Interesting history. Took my sisters retired guide dog on a leash and was told by the ranger after we hiked that no animals are allowed in the park. Noticed on your app that it says dogs are allowed on leash. You might want to update that. Ranger was unfriendly. No aloha here.

Yes, bring enough water. No, it's not like Hunger Games where everything try to kill you as written down below in other review. Yes, it's really humid. No, don't skip this hike. I'm 33 years old average hiker with beer belly and took us (with my girlfriend) 35 minutes down and 43 minutes back. Interresting hiking but more than that, great for snorkeling. We saw 20 dolphins playing and jumping from water and swam with them. Don't be affraid and just enjoy the show if you are lucky. It's remain a hik, not a walk in a park.

Tons of fun - jungle, ocean views, crystal clear water and a historical monument.
