Montanejos: Magical Night Swim Under the Stars

A warm river, a dark sky, and the sound of water moving through a canyon: that is the heart of this Montanejos night trip. After sunset, you swim at Fuente de los Baños in thermal water that stays around 19 to 21°C all year, including winter. Individual lights and waterproof gear help you find your way in the dark.

I like the small group limit of eight, which gives the evening a personal feel instead of turning it into a noisy procession. I also like the careful planning by Kiumars, known as Kiu, who provides water shoes, lighting equipment, towels, and photos so you can focus on the river rather than your phone.

The main consideration is simple: you need to be able to swim, and even basic swimming confidence matters at night. The water is warm, but this is still a real outdoor water activity. Food and drinks are not listed as included, so confirm the dinner arrangement and budget accordingly.

The best parts of the Montanejos evening

• A 19 to 21°C thermal river: The water remains relatively mild through the year, making a winter night swim possible.
• Sunset at Arenoso Dam: You reach the dam before dark, when the sky changes color above the quiet water.
• A secret waterfall stop: The first visit sets a calm tone and gives you a chance to see Montanejos beyond its main swimming area.
• The Valley of the Screaming Birds: Echoing bird calls give this canyon stop an unusual, slightly eerie mood.
• Color-coded lights and water shoes: These practical touches make the night swim easier and safer.
• A local meal after the swim: The evening ends with regional food, tapas, dessert, and drinks available as part of the dinner stop, though you should check what your booking covers.

From Valencia to Montanejos after sunset

The outing begins beside the Serranos Towers in Valencia. Look for Kiu waving a red floating noodle, an unusual but useful meeting signal in a busy city setting. Transport takes you from Valencia to Montanejos, so you do not need to arrange a rental car or work out the mountain roads yourself.

The six-hour schedule is long enough to make Montanejos feel like a proper escape rather than a quick photo stop. You leave the city, visit several natural sites, swim after dark, eat in the village, and return to Valencia in the same evening.

That timing is one of the strongest points for visitors staying in Valencia without a car. Montanejos is not a place you can casually add between city sights. The organized transport lets you enjoy the river and the sunset without worrying about driving back in the dark.

The tradeoff is that six hours makes this a substantial commitment. You will spend part of the evening in a vehicle, and the day’s exact starting time changes with availability and the season. If you want a short city activity, this is not the right choice. If you want one full evening devoted to nature, the schedule makes sense.

A quiet waterfall before the main event

The first stop is a secluded waterfall. The visit lasts about 40 minutes, including time for photos, sightseeing, and views along the way.

This stop matters because it eases you into the night. You are not rushed straight from Valencia into cold darkness and a swim. Instead, you begin with moving water, rock, and a chance to adjust to the slower pace of the outing.

The waterfall is also a good reason to wear shoes that can handle wet ground, though Kiu supplies water shoes for the river portion. Bring clothes that can cope with spray and damp surfaces. The supplied information does not describe a long hike, so you should not expect a demanding trek, but the setting is still outdoors rather than a paved attraction.

The stop works best as a mood setter. Its value is not only the waterfall itself. It changes the rhythm of the evening and makes the later swim feel like part of a sequence through the area, not an isolated activity.

Sunset over Arenoso Dam

The group then reaches Arenoso Dam for roughly 40 minutes of sightseeing and sunset views. This is the visual high point before darkness takes over.

You can expect time for photographs as the sky shifts through orange and pink tones above the dam. The quiet setting gives you a chance to enjoy the view without the crowds and noise found at many well-known sunset sites.

I like the order of the stops here. You see Montanejos in daylight, watch the last light fade, and then enter the night portion of the trip. That gradual change gives the evening a natural shape.

Bring your camera, but do not build the whole stop around taking pictures. The appeal is the stillness and the view across the dam. Weather and cloud cover will affect the colors, so the sunset cannot be guaranteed to look the same each time.

The Valley of the Screaming Birds

One of the more unusual stops is the place described as the Valley of the Screaming Birds, also called Chillapájaros. Here, bird calls echo through the canyon and create an atmospheric soundscape.

This is not a standard sightseeing stop with a long list of monuments. Its appeal comes from sound, space, and the feeling of being in a natural setting after dark. The calls may strike you as eerie, especially as the light fades. That is part of the fun, but people who dislike dark or remote outdoor settings should know what kind of mood to expect.

Kiu’s role is especially useful here. A guide can point out what you are hearing and explain the area in a way that is difficult to manage alone at night. The tour is offered in English, French, German, Persian, and Spanish, so you can request the language that works best for your group.

The stop also breaks up the drive between the sunset and the swim. You are not simply waiting for darkness. You are moving through different parts of Montanejos and experiencing the area with more than one sense.

The Fuente de los Baños night swim

The main stop lasts about 75 minutes at Fuente de los Baños. This is the part to think about most carefully before booking.

The river water stays between 19 and 21°C, or about 66.2 to 69.8°F. That is mild compared with many natural swimming spots, but it will not feel like a heated indoor pool. In winter, the water may feel pleasant once you are in it while the air around you remains cool. A full change of clothes is essential.

The setting changes after dark. The river is softly illuminated, the sky is above you, and the lights supplied by the guide help you see around the water. Color-coded blinking lights make it easier to keep track of people in the group, while underwater flashlights help with visibility.

This equipment is more than a decorative touch. Night water can make distance and direction hard to judge. The lights give the guide a way to monitor the group and give you a clearer sense of where you are. Kiu is also a lifeguard and is described as staying attentive to safety throughout the activity.

You still need basic swimming ability. The tour is not suitable for non-swimmers, and the fact that the guide can help does not remove the need for you to move comfortably in water. If you are nervous in natural water or dislike swimming after dark, you may find the main event stressful rather than relaxing.

For confident swimmers, the appeal is the calm. This is not presented as a fast water sport or a technical outdoor challenge. You float, look upward, listen to the river, and take in the night sky. The combination of warm water, darkness, and quiet creates a strong sensory experience without requiring a long hike or strenuous exertion.

The tour also includes photographs. That is useful here because getting a phone into a river at night is a bad plan, and you may prefer to keep both hands free. Ask how and when the photos will be delivered if that matters to you, since the supplied information confirms that pictures are provided but does not give a delivery method.

Dinner in the village after swimming

After the water stop, the group has about an hour for a meal in Montanejos. The food portion can include regional dishes, tapas, local snacks, dessert, beer, or wine.

This is a smart end to the evening. You have time to warm up, change, and talk about the stops before getting back into the vehicle. A meal also gives the outing a local character that a simple snack stop would not provide.

There is one money detail to handle before you go. The activity information lists food and drinks as not included, even though the evening plan describes a local dinner. Treat the meal as an additional cost unless your booking confirmation says otherwise. At $147 per person, that distinction affects the true price.

The value of the tour rests on the complete package: transport from Valencia, a guide, several stops, swimming equipment, lighting, photographs, and the small group. If you had to arrange a car, find the waterfall and viewpoints, manage a night swim, and organize a meal yourself, the fee would be easier to justify. If you only want access to the river, it is expensive.

What the small group changes

The maximum group size is eight people, with private options also available. That limit matters more here than it would on a normal sightseeing bus.

At the waterfall and dam, a small group means less waiting for photos and more space for the guide to answer questions. During the swim, it also makes the lights and safety checks easier to manage. Kiu can pay closer attention to individual needs, which is especially useful when people have different swimming confidence.

A small group does not guarantee total solitude. Montanejos is a known natural bathing area, and conditions can change with the date and season. Still, a group of eight is far less cumbersome than a large excursion, particularly once everyone is moving through the river in darkness.

Private departures may suit families or friends who want a more flexible pace. Solo visitors can also fit well into the small-group format, especially if they like outdoor activities but do not want to arrange the logistics alone.

Who should book, and who should skip it

I would choose this for an adult or older child who can swim, enjoys nature after dark, and likes an evening with several distinct stages. It suits couples, small families with confident swimmers, friends, and solo visitors who want something far removed from Valencia’s usual food and architecture outings.

It is also a good year-round option. The thermal water makes the activity possible in winter, though you should bring a warm change of clothes and be ready for cooler air outside the river.

I would skip it if you are a non-swimmer, use a wheelchair, or want a completely dry evening. The tour includes outdoor stops, a night water activity, and movement in uneven natural surroundings. It is not a passive sightseeing ride.

Bring your passport or ID card, a full change of clothes, and a willingness to get wet. Water shoes and lighting equipment are provided, but practical clothing still matters. Ask about the meal cost before departure, and confirm the meeting details: the stated meeting point is right beside the Serranos Towers, with Kiu identified by the red floating noodle.

Is $147 a fair price?

At $147, this is not a bargain activity in the usual Valencia sense. You can spend less on a normal day trip or a meal in the city. The question is what you are buying.

You are paying for a six-hour outing with transport into the Valencian countryside, a live guide, several carefully timed stops, a night swim, safety lighting, water shoes, and photographs. The small group limit adds value, especially for the swimming section. If dinner is not included, add that cost to your budget.

I see the price as fair for someone who values convenience and a rare night-time setting. It is less compelling for someone who already has a car, only wants to see the dam, or does not care about organized guidance. The experience is distinctive because all the pieces work together: waterfall, sunset, canyon sounds, thermal water, stars, and dinner.

Final decision

Book this Montanejos night swim if you can swim, want a memorable break from Valencia, and appreciate a guide who handles the practical details. Kiu’s safety focus, lights, water shoes, photographs, and small group setup make the evening easier to enjoy.

Skip it if you need guaranteed dry weather, dislike nighttime swimming, or are watching every euro. For the right person, though, floating in 19 to 21°C river water beneath the stars is the kind of simple, unusual memory that can give a Valencia trip a real sense of place.
