From Valencia: Montanejos Thermal Spring & San Jose Cave

The star of this day is the contrast: warm outdoor pools in Montanejos, followed by a boat ride through the dark chambers of San José Cave. I like the 25°C water, which stays warm all year, and the small-group format, which makes a long day out of Valencia feel more personal. The cave was the top attraction for one Italian visitor, while the driver earned special praise.

The main drawback is time. You spend about two and a half hours on the road, and the swimming stop is only around 90 minutes. Also, the tour details mention both a maximum of eight people and a limit of 15, so confirm the actual group size when booking.

Key points at a glance

• Montanejos stays warm year-round: The swimming area is listed at 25°C, or 77°F, making it suitable even outside the hottest summer months.
• San José Cave is the main spectacle: You ride by boat through an underground river for about 45 minutes.
• A 30-minute hike adds views: The route ends at a viewpoint and includes local stories and scenic stops.
• Private transport keeps the day simple: You leave Valencia from Mestalla Stadium in an air-conditioned vehicle.
• Swimming equipment is supplied: Noodles, life jackets, snorkel masks, and children’s water toys are available.
• Food is not included: Bring your own picnic or plan to buy food separately.

Two very different natural stops in one day

This excursion links two places that feel worlds apart. Montanejos gives you open air, warm water, waterfalls, and a short walk through the surrounding countryside. San José Cave shifts the mood completely, taking you underground on a slow boat ride along one of Europe’s longest navigable underground rivers.

That variety is the reason I think the trip works. You are not spending seven hours on one attraction. Instead, the day has a clear rhythm: road trip, swim, picnic, hike, cave, and return to Valencia.

The pace is still fairly tight. You will want to be ready at the meeting point and keep an eye on the schedule. This is not a loose day with hours to wander. It is a coordinated outing built around two timed activities.

Meeting at Mestalla Stadium

The meeting point is on Av. de Suècia, beside Valencia’s Mestalla football stadium. Look for gate N1 on the side facing Suecia Avenue, at the corner of the stadium.

Hotel pickup is not included. That matters if you are staying outside the central part of Valencia or carrying swimming gear. Allow extra time to reach Mestalla, especially if you are unfamiliar with the stadium area.

The vehicle is air-conditioned and used for private transport from Valencia. That is a useful comfort on the 90-minute trip toward Montanejos. You avoid arranging a rental car, finding parking, or working out the rural bus connections yourself.

The driving time is also something to accept before booking. The return journey includes another hour on the road after the cave, and the full outing is advertised at about seven hours.

The drive to Montanejos

The first leg takes around an hour and a half. Your English- or Spanish-speaking local guide leads the group and provides the day’s organization and commentary.

Because the tour is offered as a small-group experience, you should have an easier time asking questions or clarifying the plan than you would on a large coach excursion. The published information gives two different group limits, however. One description says a maximum of eight people, while the booking details say up to 15 participants. If group size affects your decision, ask for confirmation before paying.

The drive is mainly a practical transfer. Its value comes from getting you directly to the springs without the stress of driving in unfamiliar areas. Bring water, wear comfortable clothing, and keep your swimwear easy to reach.

Soaking in the 25°C pools

At Montanejos, you have about 90 minutes for swimming. The thermal water is listed at 25°C throughout the year in the swimming area, or about 77°F. That is pleasantly warm for a natural pool, though it may feel only mildly warm if you expect a hot bath.

The water temperature is one of the strongest reasons to choose this excursion outside peak summer. You can swim without relying on a hot-weather forecast, and the springs provide a clear change from Valencia’s urban streets.

The setting includes waterfalls and rocky natural surroundings. The description compares the appearance to Thailand, which gives you a sense of the visual appeal, though this is still a Spanish inland setting, not a tropical resort. Expect a natural swimming area rather than spa facilities, changing rooms, or a polished pool complex. Those details are not included, so pack with simple outdoor swimming in mind.

Equipment is provided for convenience. You can use noodles, life jackets, and snorkel masks, and water toys are available for children. That helps families avoid packing every piece of swimming gear. Still, bring your own towel and personal essentials, since they are not listed among the inclusions.

The outing is described as suitable for all ages, but it is not suitable for babies under one year. A child who is not a confident swimmer may need a life jacket and close adult supervision. The supplied equipment helps, but it does not replace an adult watching the water.

A short hike to a high viewpoint

After the swim, the group takes a 30-minute hike. This is not presented as a demanding mountain trek. It is a short walk designed to show you scenic spots, share local stories, and finish at a viewpoint.

I like this part because it breaks up the water time. Sitting in a warm pool for 90 minutes can be relaxing, but the walk gives the day some movement and lets you see more of Montanejos than the swimming area alone.

Comfortable shoes are important. The information does not give a trail grade or describe the surface, so do not arrive in flip-flops if you want steady footing. Comfortable clothes are also recommended, particularly if you are changing between swimming and walking.

The viewpoint is one of the day’s quieter rewards. You get a broader look at the area before returning to the vehicle. The guide also shares stories and points out lesser-known details along the route, though the exact subjects depend on the guide and the conditions on the day.

A quick picnic break

The picnic stop lasts about 30 minutes, and food is not included. You should bring something with you or make arrangements before leaving Valencia.

Half an hour is enough for a simple sandwich, fruit, and a drink. It is not a long restaurant meal. A compact picnic is the sensible choice because you will soon be traveling onward to the cave.

This is also a good moment to dry off, change into comfortable clothes, and check that you have your belongings. If you bring a phone for photographs, protect it from water at the springs and keep it secure during the boat ride.

Entering San José Cave by boat

The second major stop is Coves de Sant Josep, or San José Cave. The boat ride lasts about 45 minutes and takes you along the underground river inside the cave.

This is the part that received the strongest praise in the available feedback. One verified Italian booking described the cave as the most beautiful attraction of the day, while also singling out the driver as fantastic. That matches the structure of the excursion: the cave offers the most unusual setting and the clearest sense of discovery.

The cave is described as the largest navigable cave in Europe, with the longest underground river in Europe. The boat moves through the interior while you look at the rock formations and underground spaces. The ride is guided, and skip-the-line access with an express security check is included.

Do not expect a fast thrill ride. The appeal is the quiet movement through a place you cannot experience from the road or from the surface. The 45-minute length gives the cave enough time to feel like a proper visit rather than a quick photo stop.

The cave portion requires a minimum of two people. That condition is worth noting if you are planning very close to the departure date or are traveling alone. The tour also requires at least two participants overall.

What the $116 price gives you

At $116 per person, this is not the cheapest way to spend a day outside Valencia. Its value depends on how much you want handled for you.

The price includes private air-conditioned transport, a local professional guide, tickets, accident insurance, taxes, and the cave access arrangements. You also get the swimming equipment listed for the Montanejos stop. If you booked transport, entrance tickets, and both attractions separately, the costs and planning time would add up.

The strongest value is convenience. You do not need to drive to two separate natural sites, organize a cave booking, or work out how to carry swimming gear on rural public transport. The guide also keeps the day moving, which matters when the schedule includes several transfers.

The weaker value is free time. You are paying for a structured seven-hour outing, not a full day at Montanejos or a long independent visit to the cave. The swimming period lasts about 90 minutes, the picnic only 30 minutes, and the hike about half an hour.

I would consider the price fair for someone who wants both attractions in one day and prefers a small organized group. It is less appealing if you already have a car, want to spend most of the day swimming, or dislike fixed schedules.

Who will enjoy this outing most

I would recommend this trip to you if you want a nature break from Valencia without giving up comfort or organization. It suits couples, families with older babies and children, and small groups of friends who like mixing easy outdoor activity with sightseeing.

It is also a good fit if you want to swim but do not want to gamble on sea conditions. The spring water stays at the advertised temperature all year, and swimming equipment is available.

Families should note the practical limits. Babies under one year are not accepted, alcohol is not allowed in the vehicle, and smoking is prohibited. The group moves through several activities, so children need to manage a transfer-heavy day.

You may want to skip it if you want a slow, independent schedule. The road time is significant, and you cannot simply extend your swim or linger at the cave. The tour is best for people who value seeing two major natural attractions in one coordinated outing.

What to bring and what to expect

Pack a swimsuit, towel, water, food for the picnic, comfortable walking shoes, and comfortable clothes. The official list only requires comfortable shoes and clothing, but the swimming portion makes those additional items practical.

You can use the supplied noodles, life jackets, snorkel masks, and children’s water toys. Personal equipment is still fine if you prefer your own mask or flotation aid.

The guide speaks English or Spanish. The experience includes accident insurance, taxes, and safety provisions. It is not a party outing, and alcohol and drugs are not allowed. Alcoholic drinks are also prohibited inside the vehicle.

The tour offers free cancellation up to 24 hours before departure for a full refund, and you can reserve now and pay later. Starting times vary, so check the available departure when choosing a date.

Should you book this Montanejos and San José Cave trip?

Book it if you want the most efficient way to pair warm spring swimming with a memorable underground boat ride from Valencia. The cave is likely to be the visual high point, while Montanejos gives you the relaxed outdoor pause that keeps the day from feeling like one long sightseeing transfer.

I would be particularly inclined to book if you do not have a car, want equipment supplied, or prefer a guide to manage the details. Before confirming, ask about the actual group size because the published information gives both eight and 15 as the limit.

Skip it if you want a full day at one location, need hotel pickup, or prefer complete control over your timing. For everyone else, the combination is unusual, practical, and broad enough to make the long drive worthwhile.
