Rincon de la Vieja from Tamarindo: Mud Pots, Waterfalls and a Volcano on Watch

The easiest way to lose a day on Rincón de la Vieja is to set off from Tamarindo on a Monday. You drive two hours inland, climb the last stretch of road toward the volcano, and find the gate of Las Pailas closed, because Monday is its day off. The second easiest way is to arrive on the right day with cash in your pocket and no ticket on your phone, because the park stopped selling tickets at the gate in 2023.

Both mistakes are simple to avoid, and they are worth avoiding. Rincón de la Vieja National Park is the easiest big volcano day from the Guanacaste beaches: bubbling mud pots, steaming vents, dry forest, two waterfalls and a crater that has been very much awake this year. This guide covers what the volcano is doing right now, which sector to choose, how the drive from Tamarindo works, and whether a day trip is enough or a night closer to the mountain makes more sense.

What the volcano is doing this November

Rincón de la Vieja is an active volcano, and 2026 has reminded everyone of that. Between early July and mid September it produced 249 phreatic eruptions and nine lahars, according to figures reported by The Tico Times. The last moderate eruption capable of sending mudflows down the rivers came on September 9.

Things have calmed since then. On October 30, OVSICORI, the national volcano and earthquake observatory, lowered the alert level one step, from Precaución (caution) to Advertencia (warning), after a week in which all seven recorded eruptions were small. That is good news for visitors, but it is not an all clear. Small eruptions are still expected and can happen without warning.

In practice that means three things for a day trip. The crater summit trail remains closed, so nobody is hiking to the top. The Las Pailas sector, where most people go, has not announced closures of its other trails, but check before you drive. And the official advice is to stay away from river channels around the volcano and never touch or drink river water, which is where lahars travel. The national emergency commission placed several districts around the volcano on yellow alert on October 1, including Curubandé on the road to Las Pailas, so check the latest notice from the park or OVSICORI the evening before you go.

Las Pailas or Santa María

The park, created in 1973 and covering about 14,300 hectares, has two entrances that feel like two different parks.

Las Pailas is the one in every photo. It sits on the southwest side, closest to Liberia, and holds the geothermal loop, the waterfall trails and the classic mud pots. It opens Tuesday to Sunday, 8am to 3pm, and is closed on Mondays.

Santa María is the second sector, on the southeast side, reached by a rougher road. It opens Thursday to Monday, 8am to 3:30pm, and is closed on Tuesdays and Wednesdays. Its camping area is currently closed and there is no food service, so bring lunch. A 7 km linear trail links the two sectors if you have a full day and someone to collect you at the other end.

For a first visit from the coast, Las Pailas is the right choice. It is easier to reach, has the most to see in a short walk, and works with the drive back to Tamarindo before dark.

Three walks, three very different days

The Las Pailas loop

This is the walk most visitors come for: a 3 km circuit that takes about two hours at an easy pace. It passes fumaroles, bubbling mud pots, hot water pools, a steaming fumarolic lagoon and a small mud cone the park calls the "volcancito". The water and mud along the trail run between 78 and 106 °C, which explains the strict rule: stay on the path, and no bathing anywhere. Part of the loop is accessible for wheelchairs.

The waterfall trails

Two longer trails head off to waterfalls. La Cangreja is 5 km each way, and La Escondida is 4.3 km each way. Allow four to five hours for the round trip. The important detail is the cutoff: you can only start these trails between 8am and noon, so a 10am arrival after a slow breakfast leaves very little margin. Swimming is not allowed at either waterfall, and in the rainy season access can be restricted when the trails are wet.

The crater

Closed. The summit trail has been shut because of the volcanic activity, and no guide or tour can take you up legally while that holds. If someone offers, say no.

The drive from Tamarindo

Most route guides put Las Pailas at about two hours from Tamarindo, give or take traffic around Liberia. The usual route takes Route 155 inland to Belén, then Route 21 to Liberia. From Liberia the park's own directions are simple: head north on the Interamericana for 5 km to Guadalupe, then turn east toward Curubandé and follow that road for about 20 km to the entrance. The road is almost entirely paved, and a regular car is fine for Las Pailas in normal conditions.

Two small surprises. A private farm on the final approach charges a right of way fee of ₡800 per person, separate from the park ticket, so carry some colones. And pets are not allowed inside the park, so a dog travelling with you will need to stay behind.

Leave Tamarindo around 6am and you reach the gate soon after it opens, with time for the loop and one waterfall before the trail cutoff. Leave at 9am and you will be choosing between them.

Tickets are online only

Since August 1, 2023, entry tickets for Rincón de la Vieja are sold only through SINAC's online system, SICORE. There is no payment at the gate. The current fee for non resident visitors is $16.95 per adult and $5.65 per child, tax included, and Costa Rican nationals and residents pay ₡1,130.

The booking system gives you 12 minutes to complete a purchase and allows up to 10 tickets per transaction, so have every visitor's details ready before you start. At the entrance you show the barcode and the matching IDs. Buy the night before and save a screenshot of the ticket.

Green season mornings, dry season afternoons

November is the tail of the rainy season. The usual pattern is sunny mornings and rain in the afternoon. That pattern favours an early start and a walk that finishes by lunch.

From December to April the dry season takes over. In either season, bring closed shoes, plenty of water, sun protection and a light rain jacket.

Outside the park, private ranches along the approach roads sell their own hot springs, river tubing and ziplines. Those are separate businesses with their own tickets and their own rules, not part of the national park, and they are worth checking individually for how the volcano alert affects their rivers.

Day trip, or a night closer to the volcano

For most people staying on the coast, a day trip works. You see the loop, maybe one waterfall, and you are back on the beach for the evening. It is the simplest choice if you have a few days in Tamarindo and want one inland day in the middle.

A night closer makes sense in two situations. The first is if you want both the loop and a waterfall without rushing, or want to add Santa María the next day. The second is if your flight leaves from Liberia airport. The park is roughly 25 km from Liberia, so finishing a trip with a night in or near Liberia, or at one of the lodges and ranches along the Curubandé road, puts the volcano and the airport both close by. Compare options on their own merits, and with the current yellow alert in mind, choose a place that can tell you clearly how it is following the official guidance.

Going the other way, with a night near the volcano at the start of a trip, also works well for travellers flying in to Liberia who would rather not drive to the coast straight after a long flight.

Coming back to Tamarindo

If Tamarindo is your base, Surf Ranch Tamarindo is a small place with nine rooms, just across the road from Tamarindo Beach, which is exactly where you want to be after a hot, dusty morning among mud pots. There is free public parking for a rental car, dogs are welcome (though, as above, they cannot join you inside the park), and booking direct on surfranchtamarindo.com gets you our best rate plus 2% back in rewards. Questions go to booking@surfranchtamarindo.com.

Not driving? Our Liberia airport shuttle guide explains how the airport run to Tamarindo works, and for more ideas on where to base yourself along the coast, see Where to Stay in Guanacaste.

The one question to answer before you set the alarm

What day is it tomorrow? If the answer is Monday, Las Pailas is closed, and if it is Tuesday or Wednesday, Santa María is. Everything else about Rincón de la Vieja, from the ticket to the trail cutoff to the volcano's mood, can be checked the night before in ten minutes. The calendar is the one thing people forget, and it is the one that sends them back to the beach without seeing a single mud pot.
