About Mahina Hawaii in O'ahu

Experience Hawaii adventures from a local’s perspective.

At Mahina Hawaii, we avoid giving people the average tours in Hawaii. We strive to offer a personalized experience that feels more like you’re hanging out with a good friend, instead of feeling like you’re on a tour.

We take our guests to some of the most beautiful and lesser-known spots on Oahu to experience waterfall hikes, cliff jumping, snorkeling, turtles and other wildlife encounters, while sharing our local knowledge with you. Hawai’i is a very special place, and we are thrilled to take you out on an epic adventure day with us!

Hawai’i has a very fragile ecosystem here in Hawaii. It is important that you don’t walk on the reefs, wear reef safe sunscreen (read our blog about sunscreens), keep a good distance from turtles and monk seals, and make sure you leave every place cleaner than you found it. You may notice your guide picking up trash at beaches and hikes. That is to ensure that rubbish doesn’t end up in our oceans, and to leave the area cleaner for the next people to enjoy. We encourage you to do the same while you are here in Hawai’i. Mahalo nui loa.

So good we booked another day!

Had the most amazing time! Ryan who took us to all the places we wanted to go and all the local hotspots! We went Paddleboarding, snorkeling, hiking, cliff jumping and swam under secluded waterfalls. Ryan was super friendly and made sure we got the most of both days. Super easy to book especially with short notice, would recommend as a must do for anyone traveling to Oahu to get the most out of your trip!

Highly recommend

Five stars all the way! All eight of us had a great time with Ryan. He had a perfect day planned and executed a few extras along the way. Snorkeling was fantastic! The whole family explored some really cool waters. Found turtles, an eel and a large octopus. Turtle swam right between jay and Jessica. Ryan was super knowledgeable and prepared. I highly recommend using him. We loved it and will be back.

An exceedingly excellent day

Normally I'm not that into writing reviews, but this was such an amazing time that I had to. We did the full day excursion and got to snorkel, kayak, hike, and see some cool sites around the island. Ryan was incredibly helpful and took us to some great spots that were out of this world. I really could not recommend this service enough.

Highlight of our trip!

DEFINITELY BOOK THIS. My boyfriend and I really wanted to see/do all that we could in our short time visiting. Hanging out with Ryan for the day was a treat! It’s like hanging out with an old time friend. Absolutely worth the time and money. Do not bother booking with a bunch of other big companies to do hikes, snorkeling, tours, etc. This family company combines all that into an honestly awesome day of adventure. We would’ve never been able to see the breathtaking views we did without him.

Perfect day!

We had such a great day with Ryan (owner Ryan). He planned a great day of snorkeling, SUP boarding, and hiking. His love of his home state and nature made it such a fun experience! Ryan had everything covered, from equipment to snacks! He was great with my teens and made sure they were safe and we were all able to enjoy of great day! I wish I was staying longer so I could book another private tour. This is a must!!!!

Personalization is amazing.

I did the personalized full day adventure and than stayed at the B&B afterwards. Each was a phenomenal experience. The tour was specifically catered to my interests and level of competence at the different activities. As the day progressed we tweaked our itinerary to include or spend more time on certain things if I liked, or choose to go on to something more low key. It was far from any generic experience, instead, everything felt like I was just hanging out with my buddies.

Amazing way to end our honeymoon.

Our day was amazing. More then we could of asked for. We spent the day surfing, sup, eating local and jumping off cliffs. We had done other tours the days prior and now wish we just waited as this trumped the others. Ryan was our personal photographer and made sure we got the best angles. Can't recommend these guys enough.
