The experience

The day starts at San Jacinto, where the earth itself is the attraction. You walk through a fumarolic field dotted with mud pits of different sizes and depths, watching the ground churn and spit steam as geysers erupt. While you're there, locals teach you how to make tortillas by hand: the kind people eat every day in Nicaragua. It's not a demonstration you watch from a distance. You're working the dough and learning the technique that's been passed down for generations.

From the mud pits, the tour moves to the Ruins of León Viejo, the "American Pompeii." This was one of the oldest Spanish colonial settlements in the Americas, founded in 1524 and abandoned in 1610. Walking through the ruins, you see how the indigenous Imabite people lived under colonial rule, and the guide explains the history written into the stone. The site sits on the shore of Lake Managua, so after exploring the ruins you stop at the old Momotombo Port for a short walk where you can see the lake and the Momotombo Volcano across the water.

The tour ends with a swim in Asososca Lagoon (also called Laguna del Tigre), a volcanic crater lake with warm, clear water. Before heading back to León, you stop in a local artisan town for quesillo, a traditional Nicaraguan cheese dessert, and a drink. The whole experience runs 7 to 8 hours and includes private transportation, entrance fees to each site, and the snack at the end.

Top questions

What languages is the guide in?

Live guide in English and Spanish.

What exactly are the San Jacinto Mud Pits and what will I see there?

San Jacinto is a fumarolic field where geothermal activity creates mud pits of varying sizes and depths. The earth bubbles and churns, with steam geysers erupting from the ground. You walk through the field and watch nature's raw power in action. You'll also learn to make tortillas with locals during the visit.

Can I actually swim in Asososca Lagoon, or is it just a viewing stop?

Asososca Lagoon is a swimming stop. It's a volcanic crater lake with warm, clear water, and you'll have time to swim and cool off before the tour returns to León.

How long does this tour take and what time does it start?

The tour runs 7 to 8 hours total. Pickup is included, so your hotel in León will be the meeting point. Confirm the exact start time when you book.

What is quesillo and when do I get to try it?

Quesillo is a traditional Nicaraguan cheese dessert: a charming artisan town stop near the end of the tour is where you'll have it, along with a drink, before returning to León.

Do I need to be in good physical shape for this tour?

The tour requires at least a moderate level of physical fitness. You'll be walking through the mud pits field, exploring the ruins on foot, and swimming in the lagoon. The minimum age is 12, and the tour is not recommended for pregnant travelers.
