Presa Aguamilpa – Nayarit’s Hidden Hydro‑Adventure

If you think Mexico is only about beaches, tacos, and ancient ruins, think again. Nestled in the rugged heart of Nayarit, Presa Aguamilpa (Aguamilpa Dam) offers a striking blend of engineering marvel, natural beauty, and off‑the‑beaten‑path adventure. Whether you’re a road‑trip enthusiast, a photography lover, or a water‑sport fan, this dam deserves a spot on your travel itinerary.

2. About Presa Aguamilpa

A Brief History

Presa Aguamilpa, officially known as Aguamilpa Dam, was constructed as part of Mexico’s ambitious hydro‑electric program in the late 20th century. According to its Wikipedia entry, the dam was built between 1979 and 1989 on the Río Grande de Santiago. Its primary purpose is to generate renewable electricity for the western states, helping to reduce reliance on fossil fuels.

Engineering Significance

Although the exact height of the structure is not publicly listed, the dam’s massive concrete gravity design is a testament to modern engineering. The reservoir created by the dam—often called Lake Aguamilpa—covers an extensive area, offering a stable water source for power generation and recreational activities alike. The dam’s turbines spin continuously, feeding clean energy into the national grid and showcasing Mexico’s commitment to sustainable development.

Why It Matters to Travelers

Beyond its functional role, Presa Aguamilpa has become an emerging spot for eco‑tourism. The reservoir’s calm waters reflect the surrounding mountains, creating perfect conditions for kayaking, paddle‑boarding, and bird‑watching. The dam’s visitor area includes viewing platforms, informational signage, and a modest picnic zone—ideal for a relaxed afternoon away from the crowds of more commercial attractions.

3. How to Get There

By Air

The nearest major airport is Lic. Gustavo Díaz Ordaz International Airport (PVR) in Puerto Vallarta, about 120 km (≈ 75 mi) southwest of the dam. From the airport, you can rent a car or arrange a private transfer.

By Car

Driving is the most straightforward way to reach Presa Aguamilpa:

1. From Puerto Vallarta:
   - Take Highway 200 north toward San Dimas.
   - Turn left onto Highway 70 (signs for Nayarit / Santiago).
   - Continue for roughly 85 km until you see the sign for La Jarretadera; the dam will be visible from the road.

2. From Tepic (state capital):
   - Head south on Highway 68 toward Santiago.
   - Merge onto Highway 70 eastbound and follow the same directions above.

The road is paved and well‑maintained, though sections can be winding and steep—drive cautiously, especially during the rainy season.

Public Transport

Buses run regularly between Tepic, Puerto Vallarta, and the town of Santiago. From Santiago, local “colectivo” vans can drop you off at the dam’s parking lot (ask for “Presa Aguamilpa”).

Parking & Access

A modest parking lot sits at the main visitor area, with space for cars, vans, and a few motorbikes. The lot is free, but it can fill up on weekends and holidays, so arrive early for the best spot.

4. Best Time to Visit

Overall, the dry season (especially December to March) offers the most comfortable conditions for outdoor activities and driving on mountain roads.

5. What to Expect
