How Much Do Things to Do in Kona Cost? 2026 Prices

This table covers the real price range for guided experiences on the Kona side of the island as of August 2026. Prices shift with season and demand, so treat this as a snapshot and check the live price on the booking page before you commit. Last verified: August 2026.

Half-day water trips out of Honokohau Harbor sit at the bottom of that range, $75 to $200. Full-day land tours that cross into Hawaii Volcanoes National Park or up to the Mauna Kea summit run $189 to $330, and the extra hours, park logistics, and evening transport are most of what separates the two tiers.

Two things move the price of a Kona tour more than anything else: how many hours it runs, and whether it crosses onto the volcano side of the island. A two-hour boat trip out of Honokohau Harbor is a different cost structure than an eight-hour drive to a 13,803-foot summit with dinner and telescopes included.

Solo Traveler

Booking the $75 manta ray trip alone keeps the day's activity cost at $75, plus whatever you'd spend on a meal afterward, which this page doesn't itemize since it isn't a fee or fixed cost. Add the Kahaluu Beach Park stop earlier in the day, which is free, and the whole day's paid total stays at $75.

Couple

Two people on the $122 manta ray adventure pay $244 combined for the evening. Pair that with a self-drive day to Hawaii Volcanoes National Park at $30 for the vehicle (covers both of you and the car for seven days), and the two-day paid total for the pair comes to $274, before any meals or lodging, which sit outside this page's fee and tour arithmetic.

Family of Four

A family of four booking the $189 volcano, black sand beach and waterfall tour pays $756 before any child pricing, which individual operators confirm at checkout and don't publish as a fixed rate here. Add a single $30 vehicle fee if you also plan a self-drive day at Hawaii Volcanoes National Park later in the trip, since that fee covers the vehicle for seven days regardless of how many times you re-enter.

The two National Park Service sites near Kona charge separately from any guided tour, and both are card-only. Last verified: August 2026.

If you plan to visit both Hawaii Volcanoes and Puuhonua o Honaunau, or return to Hawaii Volcanoes more than twice in a year, the Hawaii Tri-Park Annual Pass at $55 covers both of those parks plus Haleakala on Maui for twelve months, and it pays for itself against the per-visit vehicle fees faster than it looks. The park does not accept cash at either gate, and there is no way around that, so bring a card even if you're used to paying entrance fees in cash elsewhere.

Hawaii Volcanoes National Park also runs a short list of fee-free days through 2026: February 16, May 25, June 14, July 3 through 5, August 25, September 17, October 27, and November 11. None of those waive the county or state taxes on anything else you book that day, just the park's own vehicle or individual entrance fee.

Hawaii's lodging tax changed at the start of this year, and it's the single most common line item visitors miss when they budget a Kona trip. The state transient accommodations tax rose from 10.25 percent to 11 percent on January 1, 2026, under Act 96 (2025), and counties can add a further 3 percent surcharge on top of that. General excise tax applies on top of both, running about 4.7 percent on the Big Island once the county surcharge is folded in.

Add those together and a Hawaii hotel bill in 2026 carries roughly 18 to 19 percent in tax, before any resort fee or parking charge a property adds separately. On a $200-a-night room, that's about $36 to $38 in tax alone, on top of whatever the nightly rate already is. Write it down as "about" rather than to the cent, since the exact combined rate depends on which county surcharge applies and how a given property itemizes it.

This is a tax on the room, not on tours or park admission, so none of the fee figures elsewhere on this page carry the same percentage. For where to actually stay on the Kona side and what current listings run, see Kona versus Hilo for where to stay.

Here's a real week of paid activities and fees for a couple, built only from the prices verified on this page. Lodging and food aren't itemized here since neither has a verified per-night or per-meal figure in this pack, they're their own line items you'll fill in against whatever you book.

That's $1,312 in activities and park fees for two people across a week, not counting lodging (add roughly 18 to 19 percent tax to whatever the nightly rate is), meals, or a rental car, none of which have a single verified figure that applies across every trip. If you'd rather skip the rental car on the lighter days, Hele-On county buses cost nothing to ride through 2028, though the network runs limited daily frequencies and doesn't serve trailheads or dive sites, so it works for in-town errands, not for reaching a tour meeting point.

A handful of real stops in Kona cost nothing, and they're worth stacking against a paid day rather than treating as a separate trip.

• Kahaluu Beach Park, a free county beach park on Alii Drive, shallow and sheltered, the standard beginner shore snorkel spot in Kona
• Kaloko-Honokohau National Historical Park, just north of town, no entrance fee, with ancient Hawaiian fishponds along the shoreline
• The Kailua-Kona waterfront itself, including Ahuena Heiau and Huliheʻe Palace, both viewable without an admission fee to walk past
• The Kona farmers market on Alii Drive, open Wednesday and Saturday mornings, no entry cost to browse

None of these substitute for a tour if what you actually want is manta rays at night or the Mauna Kea summit, but stacking one or two free stops against a paid day is a real way to keep a week's total closer to the lower end of the range in the table above.

A few real ways to bring the total down without cutting the trip short.

• Book the $75 manta ray boat trip instead of the $122 adventure if the difference matters more than the extra amenities, both leave from Honokohau Harbor and cover the same wildlife
• Get the $55 Tri-Park Annual Pass if you're visiting Hawaii Volcanoes and Puuhonua o Honaunau, or returning to either more than a couple of times, rather than paying the $30 and $20 vehicle fees separately each visit
• Time a Hawaii Volcanoes visit around one of the 2026 fee-free days (February 16, May 25, June 14, July 3 through 5, August 25, September 17, October 27, November 11) to skip the $30 vehicle fee entirely
• Ride the fare-free Hele-On bus for in-town errands instead of paying for a rental car that day, it costs nothing to ride through 2028
• Stack a free stop, Kahaluu Beach Park, the farmers market, or Kaloko-Honokohau, on the same day as a paid tour rather than budgeting it as its own outing

For where the bigger trip-length decisions live, how many days to plan for Kona and whether you need a car at all both change the total more than any single tour choice does.

Ways to take money off the total

None of these need you to book the cheapest thing on any list.

• Buy the $55 Tri-Park annual pass if two of the national parks are on your route
• Check the National Park Service fee-free days, which in 2026 include August 25, September 17, October 27 and November 11
• Book the manta trip early rather than late, since the cheaper departures fill first in summer
• Take the fare-free Hele-On bus for any trip its timetable actually covers
• Bring your own mask and snorkel so shore days cost nothing at all
• Budget roughly 18 to 19 percent on top of a room rate for state and county tax before you compare two hotels
