Planning a trip to Guanacaste or staying near Liberia, Coco, Hermosa or the Riu hotels? Diamante Eco Adventure Park is the one place where you can tick off Costa Rica adrenaline, wildlife, beach time and proper food in a single day – and when you book directly or pay at the counter, you can use the code HOWLER for a 10% discount on your pass.
Where is Diamante Eco Adventure Park and why is it ideal for a Costa Rica day out?
Diamante Eco Adventure Park sits on an oceanfront hillside in Guanacaste, giving you Pacific views, jungle canopy and beach access all in one spot. The park is just a short drive from Liberia International Airport and popular beach towns, so you can easily fit it into a holiday without losing a full travel day. (Diamante Eco Adventures)
You arrive at a modern welcome centre perched above the sea, with sweeping views that already feel like a reward before you’ve done a single activity. From there, everything is laid out sensibly: zipline launch, animal sanctuary, cultural area and beach access, so you are never wasting time in a minibus between attractions. The Adventure Pass bundles the best of the park in one ticket – zipline, animal sanctuary, cultural experience, botanical garden, beach activities and a buffet lunch – which is where that HOWLER 10% discount really starts to earn its keep when you book direct or pay at the counter.

What adventures can you experience in one day?
In a single visit you can fly, explore, paddle and relax, moving from high adrenaline to full chill as the day unfolds.
Here is what a typical Adventure Pass day can include: (Diamante Eco Adventures)
- Superman ocean-view zipline
Soar face-first for nearly a mile on Costa Rica’s most famous dual “Superman” line, looking straight down at jungle canopy and turquoise Pacific. Dual cables mean you can race a friend, and an automatic braking system keeps the landing smooth and stress-free, even for first-timers. (Diamante Eco Adventures) - Animal Sanctuary and wildlife education
Wander shaded trails past rescued sloths, jaguars, toucans, monkeys and reptiles in one of the country’s most respected wildlife education centres. Guides share stories about each species and the conservation work behind the scenes, so you leave with more than just photos. (Diamante Eco Adventures) - Cultural experience and traditional house
Step into a replica farmhouse from 100 years ago, taste fresh sugar cane juice, see coffee and cocoa processed the old-fashioned way, and understand how rural life shaped modern Costa Rica. It’s a hands-on stop that breaks up the adrenaline with something authentic and grounded. (Diamante Eco Adventures) - Botanical garden and walking trails
Stroll through a garden full of fruit trees, flowering plants and native species that keep birds and butterflies busy all day. The paths are clearly marked and easy to follow – perfect for a slower hour between bigger activities. (Diamante Eco Adventures) - Beach club and ocean activities
Finish by heading down to the beach for stand-up paddleboarding, kayaking, snorkelling and swimming, or simply grab a lounger and watch the colours on the water change as the afternoon light shifts. (Tripadvisor)
Book your pass directly through Diamante and remember to enter or mention the code HOWLER for 10% off your chosen activity; if you decide on the day when you arrive at the counter, you can still say “HOWLER” at payment time to claim the same saving.
What is new and unmissable at Diamante right now?
Recent updates at Diamante focus on making the park smoother, more comfortable and more flexible for families and mixed-ability groups.
The park has leaned into the “something for everyone” idea, adding and refining: (Diamante Eco Adventures)
- Better flow between experiences
Updated wayfinding and staff stationed throughout the park make it simple to move from ziplining to the sanctuary or beach without feeling lost or rushed. - Family-friendly facilities
Clearly marked trails, shaded rest areas, baby changing spots and helpful bilingual staff mean multi-generational groups can enjoy the day together, not split up by pace or comfort levels. - Refreshed storytelling in the cultural and wildlife areas
New interpretive signs and guide briefings highlight sustainability, rescue stories and local culture, so your photos come with real context.
If you are gifting the park to someone else, these new touches are important: a family staying at a nearby resort can easily navigate the day even if it’s their first time in Costa Rica. Again, buying that visit as a gift certificate and sharing the HOWLER 10% discount is a simple way to look generous and smart at the same time. (Diamante Eco Adventures)
What is the food like at Diamante’s restaurants?
Food at Diamante is far better than “theme park standard”, with a highly rated Costa Rican buffet and casual grills and bars spread around the property. (Diamante Eco Adventures)
Expect to eat properly, not just snack, thanks to three main options:
- Welcome Center ocean-view buffet
A generous Costa Rican buffet with rice, beans, grilled chicken, pork rinds, a big salad bar, fresh bread and pizzas for the kids, plus fries and rice pudding for dessert. Natural fruit drinks are included, and the dining room looks straight out over the Pacific, so you never feel far from the scenery. - Adventure Center Bar and Grill
Perfect after ziplining or ATV, this spot serves burgers, hot dogs and cold drinks – exactly what your adrenaline-fuelled self is craving when you come off the lines. - El Patio bar by the Sloth Courtyard
A relaxed corner for smoothies, daiquiris and snacks while you watch people fall in love with Lucy the sloth and her neighbours.
Many reviewers pick out the buffet specifically as one of the best they had in Costa Rica, praising both quality and variety – so timing your Adventure Pass to include lunch is a wise move, especially once you’ve knocked 10% off with HOWLER. (Howlers Costa Rica Real Escapes)
Why do visitors rave about Diamante’s service and experiences?
Guests praise Diamante for combining big thrills with professional staff, well-run operations and a genuine sense of care for animals and visitors alike. (Diamante Eco Adventures)
Typical themes in customer reviews include:
- Confident, friendly guides
Zipline teams are described as efficient, calm and reassuring, which matters if someone in your group is nervous about heights. - Well-kept, ethical animal sanctuary
Visitors highlight how clean the enclosures are, how knowledgeable the guides sound, and how strongly the park emphasises rescue, rehabilitation and education rather than “photo props”. - Full-day value

When you factor in the HOWLER 10% saving on top, that sense of value only improves – especially for families or small groups buying multiple passes.
