The celling is so close you can touch it

This hidden place makes for great photos but is only for EXPERIENCED ocean swimmers. Do not go at a rising tide or high tide. The ocean floor is made up of large coral pieces and the tide pushes you around. It's very claustrophobic and the hole to get in and out takes incredible muscle strength. If you're not athletic you have no business being down here as the only way out is using upper body strength to pull you up & out. The local vibe is heavy too and as you walk towards the caves there's a cross memorial along the way.

Beautiful quick stop. The waves were perform so I couldn't wander below into the cave area but it was just a lovely sight. There were little crabs wandering around too.

Be careful! Best time to go is before 10am during lower tides. When it was nearing 11, the waves were getting higher and more frequent, making it harder to explore inside. Sharp rocks under the water can cause some serious damage. Otherwise, it's a great experience! Great photo op!

Beautiful place to visit to look, but very dangerous place to swim. This side of the island has fewer tourists so the beaches are less crowded. The mermaid caves are a lesser known area so it was empty. There were several other people on the beach, but we were the only people at the caves. We hoped for a lovely visit to these beautiful caves, but it turned out to be more depressing than anticipated. Unfortunately there are numerous gravestones here. I am unsure if some people chose to be buried here or if everyone buried here passed away in these caves. The grave stones serve as a good warning to visitors. Being non-locals, we did not dare go below into the caves even if we wanted to. Yes I'm sure it is beautiful down there but not worth the danger. You will get a beautiful view from the surface. Parking and bathrooms are located nearby. Watch your footing as it is easy to fall. The beach nearby is better suited for children, I would not recommend bringing children to these caves.

Beautiful little hidden Gem

Beautiful location, little challenging to maneuver in and out of cave. If you find this hidden Gem go with friends. Go when it's low tide.

This place was amazing. You will need a ladder to get up and down, but it's worth the work.

Pokai Bay Beach Park is a nice little local park without a lot of tourists and a perfect place to…read morehobnob with locals. The beach is protected by a sea walk, so the water is a bit calmer than other beaches making it perfect for small children. The park has restrooms (although, they need some attention) and a small playground. My granddaughter spent a good hour playing on the playground. A lot of picnic tables are scattered throughout the park. Signs request no feeding of ferrel animals in the park. The highlight of the park for me is the presence of Ku'ilioloa Heiau historical Hawaiian ruins, which are protected within the park. The temple ruins are on a small peninsula at the center of the park. The ruins are maintained by the Honolulu Department of Parks and Recreation. Fishing is a popular pastime in the park. Fishermen perch themselves on the seawall or on the volcanic rocks below the point to fish. The beach area is lovely with the mountains in the background and ocean in front. The park is a perfect place to watch the sunset. There is plenty of free parking at the entrance of the park.

The waters at this beach is a bit calm due to the sea walk. There are bathrooms here, but it isn't the nicest (typical public restrooms). If you walk just a few minutes away from the beach towards higher ground toward the cliffs, you get an amazing view of the surrounding mountains. There are plenty of trees for shade and a grass to set up tents and BBQ. There are some homeless? by the parking lot, so always be careful about locking up your cars. The people who come are a mix of mainly locals and tourist. I went during the day, mid afternoon, and felt very safe. There were plenty of parking. Everyone was just enjoying themselves.

This west side Pink Pillbox Trail isn't as famous as the east side's Lanikai Pillbox Trail, but…read moreit's only about a 15-minute drive from Aulani and way less crowded -- definitely a nice bonus. Just set your GPS to Puʻu O Hulu (Pink Pillbox) Trailhead, and you'll find plenty of street parking along that stretch. Still, I'd recommend parking closer to the entrance for safety because we noticed broken glass scattered on the ground further down the road, probably from past break-ins. We actually parked once, saw the glass right by our car, and quickly moved closer to the entrance instead. Right after we parked, it started raining. The forecast said it would last about 30 minutes, so we just waited it out in the car before starting our hike. The trailhead is right between a yellow "Falling Rocks" warning sign and a white "Speed Limit 25" sign on a utility pole. The hike starts with a steep incline, but overall it's not too hard and just a bit narrow at parts. There are three pillboxes total. It took us around 30 minutes to reach the first one at a relaxed pace, stopping for photos along the way. The first pillbox is painted in blue graffiti inside, and from there you can continue up to the famous pink one. When we got to the pink pillbox, there were surprisingly tons of flies swarming around the entrance for some reason, so we didn't stay too close. The wind was really strong up there -- strong enough that I had trouble keeping my balance! It looked like reaching the third pillbox would require climbing over quite a few rocks, so we decided to turn back instead. On the drive back, we passed Ulehawa Beach Park, where we saw a whole row of homeless encampments right by the ocean -- literally parked and camped along the beachfront. We even saw a few people running across the road and one guy riding his motorcycle the wrong way, yelling at drivers passing by. If that's a regular thing, really sad to see this.

Now this was a fun and short hike! The older I get and the older age of the guests I take on hikes,…read morethe more interested I am in completing hikes that get straight to the point - the view! This hike falls in that category. Make your way to Makaha and park on a neighborhood street. Please be respectful of where and how you park to show respect to the locals living in the area. Please ensure to not leave any trash and if you see any, please pick it up and dispose of it properly. It's just a short 3-minute walk to the base of the little hike. I believe it took us 15-20 minutes to make it to the top. I felt comfortable enough to allow my 5 year old daughter hike on her own with my supervision. There were a couple challenging spots, but as long as you push through, you should be good. The view from the stop is absolutely stunning. Since the hike is on the makai side, you can capture a full 360 view around. P.S. Waianae/Makaha is synonymous with choke homeless people and Hawaiians. Please plan appropriately.

She decided not to do the bit of "rock climbing" involved, and stayed behind with my dog. Still a very worthwhile view for just 10 minutes of work (or less). I went on, and while the rock climbing was very short, it is not for everyone. It is not extremely clear how to climb it (for someone without a lot of rock climbing experience aka me), but if you were to fall, the probably of it being fatal seems low. Gorgeous views to your left and right when you get to the top. Skip the "right fork". Just a little beach walk. We were done with both sides in less than an hour.
