Where you actually leave the car at Keauhou Bay, how long the walk down to the water takes, and how the different check-in formats work once it is dark.
Updated 21 October 2026
Free street parking on Kaleiopapa Street is the realistic answer for almost everyone. The pier at Keauhou Bay has only a limited number of spaces, and operators working out of the bay tell guests to allow 3 to 5 minutes on foot from the street down to the water. Park facing the way you came in so you are not reversing in the dark on your return.
Drive about 7 miles south out of Kailua-Kona and the road brings you to a bay sitting right inshore of the lit feeding area off Kaukalaelae Point, next door to the OUTRIGGER Kona Resort & Spa. That is the whole reason to come here rather than drive north: boats are over the rays in about five minutes instead of motoring more than 45 minutes each way from a northern harbour.
Nothing official is published about a gate or a closing time for the harbour lot, so plan on the street parking and take a pier space only if one happens to be open when you pull in.
This 2.5-hour night snorkel, from $138 and rated 4.8 ★ (6332 reviews), meets at the brown-roofed restrooms with the pavilion inside the harbour, a landmark you can find in the dark, and includes gear, a jacket-style wetsuit top, a flotation device, bottled water and light snacks.

Three formats operate out of the same bay. One Keauhou operator has no office at all for manta trips: you meet the crew at the end of the finger pier, at the bottom of Kaleiopapa Street, 15 minutes before departure. Another checks guests in at an office on the same street, at 78-7130 Kaleiopapa Street, 30 minutes before the boat goes. Canoe guests have the earliest call of the three and are asked to be at the Keauhou Bay Boat Ramp 30 minutes before the paddle out.
Read your own confirmation before you set the alarm, because not every Kona manta trip checks in at the bay. At least one departure on this coast asks guests to check in at an office in Kailua-Kona town first, and turning up at the boat instead means being sent back into town.
The small-group night snorkel on this site has you walk from the car down to the boat dock at Keauhou Harbor, half an hour ahead of departure; the marker to look for in the dark is a white van with lights on its roof. The longer 2.5-hour trip meets inside the harbour: after turning in, take the first road on the right, pass Boat Storage and the Sea Store & Deli on the left, then turn left, and the crew is at the small brown-roofed restrooms with the pavilion. The 1.5-hour tour sets out its meeting point in the ticket details.
| Tour or operator at the bay | Where you meet | How early |
|---|---|---|
| 1.5-hour night snorkel on this site, from $125 | As set out in the ticket details | Time given on the ticket |
| 2.5-hour night snorkel on this site, from $138 | Brown-roofed restrooms with pavilion, inside the harbour | Time given on the ticket |
| 1-hour small-group night snorkel on this site, from $145 | Keauhou Harbor, by the boat dock, white van with lights on top | 30 minutes before |
| Keauhou catamaran operator | End of the finger pier, bottom of Kaleiopapa Street | 15 minutes before |
| Keauhou operator with a street office | 78-7130 Kaleiopapa Street | 30 minutes before |
| Paddle outrigger canoe operation | Keauhou Bay Boat Ramp | 30 minutes before |



The state tourism authority lists the bay's amenities as parking, restrooms and a small boat ramp, with kayaking, stand-up paddleboarding and fishing going on here during the day. The restrooms sit near the parking area, a short way above the pier, so use them on the way down rather than hunting for them after the boat ties up.
The ramp is the launch point for the canoes and the small craft, and it is busy with trailers around departure times. Keep clear of the ramp apron while you wait, and come down already dressed in your swimsuit under your clothes with slip-on shoes you can step out of on deck.
Swimming at the bay is not an option the tourism authority supports: its page advises against swimming or snorkelling in Keauhou Bay because of fishing and tour-boat traffic. The mantas are offshore around Kaukalaelae Point anyway, reached by boat in about five minutes or by paddle canoe in 7 to 10.
Build in the cushion the operators ask for. Departures here follow sunset rather than a fixed clock and are confirmed at booking, and check-in lands somewhere between 15 and 30 minutes ahead depending on which boat you are on. Arriving with the engine still warm and five minutes to spare is how people miss the pier walk.
Leave nothing visible inside the car. A towel on the back seat is fine; put a daypack, a camera bag or a phone out of sight in the boot before you walk away. One small bag with a towel, a dry layer and your keys covers the entire evening, and the keys can go in the crew's dry box rather than into the water with you.
Carry a small torch or use your phone light for the climb back up to Kaleiopapa Street. The walk is short, but you will be doing it wet, in the dark, among parked cars. Keep valuables off the boat entirely where you can: one Keauhou operator bans neck lanyards for phones along with underwater flash, and a phone on a strap in black water is the item most likely to be gone by the time you notice.

Work backwards from the departure time in your confirmation and aim to be parked 45 minutes before it. That covers a 30-minute check-in at the longest end, the 3 to 5 minute walk down, and a loop along Kaleiopapa Street if the first stretch is full. If your tour only wants you 15 minutes ahead, you have spare time to use the restrooms rather than a problem.
If you are staying in the Keauhou area, this is a short hop and the smallest-group option on this site suits you: 1 hour in all, from $145, rated 4.8 ★ (1184 reviews), meeting at Keauhou Harbor 30 minutes before departure. Coming from Kailua-Kona, you have roughly 7 miles of coast road to cover southbound at dusk, so add a margin on top of the 45 minutes rather than trusting a map estimate.
Book a Keauhou departure instead of a northern harbour unless you specifically want the Garden Eel Cove site. The crossing here runs about five minutes each way, so the ticket buys you time in the water, and the drive to the bay ends up being the longest part of your evening.
Street parking on Kaleiopapa Street is free according to the operators working out of the bay, and that is where most manta guests leave the car. The pier itself has only limited spaces. Allow 3 to 5 minutes to walk down from the street to the boats, and check on the day, since harbour arrangements can change.
Yes, the names are used interchangeably on tickets for the same small harbour south of Kailua-Kona. One tour on this site gives its meeting point as Keauhou Harbor, near the boat dock, and another describes the brown-roofed restrooms with a pavilion inside the same harbour. Both are a few minutes' walk from the Kaleiopapa Street parking.
Keep driving to Kaleiopapa Street rather than waiting for someone to leave the pier. Pier parking at Keauhou Bay is limited and manta boats arrive and depart close together, so spaces turn over slowly. Build your timing around the street and the 3 to 5 minute walk down to the boats.
Leave them in the boot or at your accommodation, with nothing visible inside the car. One Keauhou operator prohibits neck lanyards for phones in the water as well as underwater flash, so a phone is of limited use once you are on the float line. A towel, a dry layer and your keys are all you need on the pier.
Keauhou departures
Park, then walk to the boat dock at Keauhou Harbor half an hour ahead of the small-group departure; a guide, equipment, an optional wetsuit and beverages are part of the ticket.
