How to see bioluminescence from Santa Teresa in 2026: the Paquera and Isla Cedros bay tours, kayak vs boat, $35 to $85 prices, pickup times and total duration, which moon phases and months work, what you actually see, and which operators are running.
The bioluminescence tour from Santa Teresa is a night trip to Paquera Bay, 90 minutes away by road, where plankton light up blue when you paddle or swim. Kayak tours start at $35 and boat tours at $40 if you drive yourself; Santa Teresa operators charge $70 to $85 with pickup. Go near the new moon.
The short version
The glow is real and it is better than the photos, which is lucky, because there will be no photos. Paquera Bay, near the ferry landing on the gulf side of the peninsula, is one of the most reliable bioluminescent bays in Costa Rica, and every tour sold in Santa Teresa, Mal Pais and Montezuma ends up there or in the calm coves around Isla Cedros and Tambor. You can see it year round. The variables that matter are moonlight, cloud, and how calm the water is, and the tour operators plan around the lunar calendar, so if the dates you ask for are near a full moon, they will tell you.
Book through Tiko Tours or Zuma Tours in Santa Teresa if you want pickup, or drive to Paquera and book Bahia Rica's kayak tour if you have a car and want the cheapest, most intimate version. The bioluminescence combines well with the Isla Tortuga day trip, which leaves from the same side of the peninsula.
What you actually see
The light comes from dinoflagellates, single-celled plankton that flash when the water around them is disturbed. In the dark, every paddle stroke leaves a trail of blue sparks, fish shoot past as streaks, and when you put your hand in and lift it out it comes up covered in what looks like glowing glitter for a second or two. On a good night you can swim in it, and your whole body outlines in blue. On an average night it is a faint shimmer that you have to move to provoke. The guides know the difference, and the honest ones will tell you at pickup what tonight looks like.
Phones cannot capture it from a moving boat. A camera on a tripod on shore with a long exposure and someone splashing can get a frame, and one or two guides will try for you, but the operators' own advice is to put the phone away. Plan on remembering it.
When it works
Moon phase matters most. The week either side of the new moon is best, the days leading up to the full moon are worst, and some operators stop running tours for a few nights around the full moon because the glow is washed out. Check a moon calendar before you pick a date. Our full moon parties guide covers the other end of the cycle; a full moon party night is the wrong night for this.
Season matters less than people think. The plankton are there all year. Dry season, December to April, gives clearer skies and calmer water, so the sky is dark and the bay is glassy. Green season, May to November, brings cloud that blocks the moon (good) and rain that stirs the water and can dilute the glow (bad), and the drive back over the hill in the dark in a storm is not fun. Right now, in late September, tours are running, the water is warm, and the trade is a wetter road for fewer people. Warm, still nights after a hot day are the ones the guides like.
Bioluminescence Tour from Santa Teresa
The Bioluminescence Tour from Santa Teresa listing is the booking page run by the santateresacostarica.com tour desk, and its 2026 menu is the clearest price list in town. A two-hour kayak tour in Paquera is from $35 per person and a two-hour boat tour from $40, both meeting at the bay, which suits people with a car. The three-hour boat tour from Santa Teresa is $70, and $85 with transport from your hotel; a private boat with transport is $360 for the group. The office is open until 11pm most nights, because the tours come back late. Who it suits: anyone who wants a straight price without haggling at a desk. The caveat: it is a reseller, so ask which captain and which bay you are being booked onto.
Tiko Tours
Tiko Tours is a Santa Teresa operator based in Playa Carmen, rated 5.0 from 86 reviews, that runs Isla Tortuga, Curu and Montezuma trips and lists bioluminescence on its menu. Its bioluminescence price is not published on the site, so expect it in the same $70 to $85 range with pickup and confirm by WhatsApp. Tiko's reviews praise the guides and the small groups on its other tours, which is the thing you want on a night kayak. Open 8am to 5pm for bookings.
Zuma Tours
Zuma Tours at Plaza Kahuna in Santa Teresa, with a second office by the Montezuma football field, has been running boats on this coast since the 1990s and sells a Sunset and Bioluminescence Tour that leaves in the late afternoon so you get the sunset from the water before it goes dark. It is rated 4.6 from 83 reviews in Santa Teresa and 416 in Montezuma. It is the biggest operator, which means the most departures and the largest groups; ask how many people will be on your boat.
Montezuma Tours
Montezuma Tours runs a bioluminescence tour from Montezuma with both kayak and boat options and, conditions permitting, a swim in the glow. Its own page says the tours are planned around the lunar calendar, that the best nights are new moon nights in the dry season, and that photos are hard and you should enjoy it with your eyes. It is rated 4.6 from 45 reviews. Who it suits: people staying in Montezuma, which is about 30 minutes closer to Paquera than Santa Teresa is.
Adventure Nicoya
Adventure Nicoya is a tour desk in the centre of Montezuma whose whole pitch is bioluminescence and hidden beaches. Its website was down when we checked in September 2026, so treat it as a walk-in or WhatsApp booking, and ask which bay the boat goes to. Its single Google review is a 5.0, which is not enough to judge.
Sun Trails
Sun Trails in Montezuma, better known for its zipline over the waterfalls, also lists bioluminescence among its tours and runs its own shuttles, so it can pick up in Santa Teresa. Prices are on request. It is a sensible choice if you are already booking the canopy with them and want one WhatsApp thread for both.
Bahia Rica, Paquera
Bahia Rica is the kayak operator at Punta Cuchillos, ten minutes from the Paquera ferry landing, and it is the tour that travel writers keep recommending: about $36 for 90 minutes, small groups split between guides, and no bus ride. It has no listing on Onda yet. You need a car to use it (the drive from Santa Teresa is about 90 minutes each way, the last part dark and winding), or you can combine it with a night in Paquera or Tambor before a ferry.
SUP at night
Costa Rica Surf and Sup runs a $130 five-hour paddleboard expedition in the Pochote estuary near Tambor and adds a bioluminescence paddle at the end for $50, and Monkey Adventures advertises a bioluminescent SUP tour on its site. Standing on a board over glowing water is the best version of this if you can balance in the dark. Both are small operators, so book several days ahead. Our kayak and SUP guide covers both in daylight.
Kayak vs boat
Kayak is the intimate option: you make the light with every stroke, you can trail your hands, and the groups are small. It needs basic fitness, and doubles are the norm. Boat tours suit families, anyone who does not want to paddle for an hour, and nights when the water is choppy; the captain finds a calm cove, cuts the engine, and everyone jumps in. The boat tours from Santa Teresa are usually longer (three hours on the water) and include the sunset. If you are choosing for kids under about ten, take the boat.

Practical notes
Pickup from Santa Teresa is usually between 3:30 and 5pm depending on sunset, the drive to Paquera is about 90 minutes, you are on the water from dusk for one to three hours, and you are back between 10 and 11pm. Eat before you go or bring snacks; some tours include a drink and a snack, few include dinner. Wear a swimsuit under quick-dry clothes, bring a towel and a dry change, a light rain jacket in green season, and reef-safe repellent, because the bay is mangrove-edged and the mosquitoes come out at dusk. Leave the flashlight in the van; guides ask for total darkness on the water.
Book two or three days ahead in green season and a week ahead in dry season, and give the operator your dates before you fix them, so they can steer you away from the full moon. Cards are fine at the desks; the boat captains at Paquera prefer cash. Tours cancel for lightning and for dangerous swell in the gulf, which is rare, and are rebooked rather than refunded.
If you are also doing Isla Tortuga, the day trips guide explains how to stack a Tortuga day and a bioluminescence night with one night in Tambor or Montezuma so you are not doing the mountain road twice in the dark.
FAQ
Where is the bioluminescence near Santa Teresa?
In Paquera Bay on the gulf side of the peninsula, at Punta Cuchillos near the ferry landing, and in the calm coves around Isla Cedros and Tambor. It is about 90 minutes by road from Santa Teresa, which is why every tour from town runs as a five to six hour evening with transport.
How much does a bioluminescence tour cost from Santa Teresa in 2026?
$35 for a kayak tour and $40 for a boat tour if you drive to Paquera yourself. From Santa Teresa with hotel pickup, expect $70 to $85 per person for a three-hour boat tour, or about $360 for a private boat. The 13% tax may be added on top.
When is the best time to see bioluminescence in Costa Rica?
Any month, on the darkest nights: within about a week of the new moon, with no moon in the sky during the tour. Dry season (December to April) gives clearer skies and calmer water; green season gives cloud that hides the moon. Avoid the four or five nights before a full moon.
Can you swim in the bioluminescence?
Yes, on most boat tours and some kayak tours, when the water is calm and the captain allows it. Your arms and legs glow blue as you move. Bring a swimsuit under your clothes and a towel; the water is warm all year.
Can you take photos of bioluminescence?
Realistically no. Phones and normal cameras record black from a moving kayak or boat. A tripod on shore with a long exposure can catch it, and a few guides try, but every operator tells you to put the camera away and watch.
Is bioluminescence worth it from Santa Teresa?
Yes, if you pick a dark night and go with a small group. It is a long evening for a two-hour glow, and the drive back over the hill at 10pm is tedious, but on a new-moon night with calm water it is the single most memorable thing most visitors do here that does not involve a surfboard.
