What a great day!!!! Seamus is the best tour guide ever!! He picked my husband and I up from our resort in Ko Olina and he was right on time. After explaining all the covid sanitation standards that he provided (which was A++), he wanted to know what we were really interested in so that he could customize the day for us. We didn't want to head to any beaches but rather we wanted to walk as many trails as we could. We hit three trails, with the 3rd being Lalumha Falls which was amazing. You have to be prepared for mud, which he "warned" us about, and yes, it was muddy!!! But, what a trail!!!! There is no way I would want to hit that trail without a guide, at least not the 1st or 2nd time. It was just breathtaking the whole way, especially when we got to the falls. We had a some extra time left at the end of our day and Seamus continued to offer more hiking or lookout opportunities so we really had a chance to get a full day in. I highly recommend Seamus --- he knows something about everything in Oahu too, so you will get tons of intel!!! (and lunch in Kailua (fish tacos) was amazing!!)
