Beginner Spearfishing Lesson
Hawaiian Reef Spearfishing Lesson for Beginners on Kauai runs through Pomai Ka'i. Rated 4.9 across 94 reviews. Runs 3 hours (approx.). From $135.
Fishing on Kauai splits into three very different experiences. You can learn Hawaiian reef spearfishing in about three hours, head offshore on a private deep water charter, or cast for bass at Waita Reservoir near Koloa. This page compares all three, with published prices and ratings from the live listings so you can pick the trip that matches your experience level and budget.
The spearfishing lesson with Pomai Ka'i runs from $135 per person, rates 4.9 across 94 reviews, and needs no prior experience. The private deep water charter from Explore Kauai Scuba is a bigger commitment at $1700 per group (up to 6) for roughly six hours offshore. Waita Reservoir bass trips start at $141.36 per person for three hours. All three listings carry free cancellation.

Check availability →Start with the water you want to fish. Reef spearfishing keeps you close to shore, working shallows with a guide who teaches breath control and species identification. Deep water charters chase pelagic fish well offshore, which means a longer day and a much higher price. The reservoir trip is the outlier: calm freshwater, no seasickness, and bass rather than reef fish.
Experience level matters more here than on most tour categories. The spearfishing lesson is built for beginners, while the deep water charter assumes you already know your way around a rod and a boat. Group size matters too. Two of the three options are private, so the per-person price covers the whole outing rather than a shared seat.
Book any of these as soon as your travel dates are firm, since private charters run on a single boat with limited departures. The deep water trip runs about six hours, so plan a full day around it, while the spearfishing lesson and reservoir trip each take around three. Every listing here offers free cancellation, which gives you room to shift plans if the weather turns or your schedule changes.
