The beach at Faifai is easily accessible, as we parked behind hotel Nikko and hiked for about 20 minutes to get there via Gun Beach. We went during low tide, which made it perfect to walk alongside the cliff with our water shoes on. There is a trail that supposedly goes around and alongside the cliff side of Gun Beach, but the planks that used to be there to get to the point of access to Faifai are no longer there. Despite this, the beach was pretty secluded and we had it all to ourselves, which was awesome! It's a great place to snorkel, even during low tide, and I was able to get out past the reef.
