This 920-Acre Ultra-Luxury Resort Just Opened on Mexico's Pacific Coast — With Just 91 Rooms

Siari, a Ritz-Carlton Reserve, has officially opened along Riviera Nayarit's coastline north of Puerto Vallarta, bringing one of Mexico's most ambitious luxury resort projects to life on 920 oceanfront acres.

The property is deliberately small by design. Just 91 rooms and suites — including a five-bedroom Presidential Estate — are spread across a landscape that stretches nearly 4.3 miles of beach, blending cliffside architecture with jungle canopy. Mexico City studio Bernardi + Peschard Arquitectura designed the resort to feel like an extension of the terrain rather than something built on top of it.

Amenities match the scale of the land. A 28,000-square-foot spa anchors the wellness program with hydrotherapy circuits, plunge pools, and an infinity pool over the Pacific. A Tom Fazio-designed championship golf course — reserved exclusively for resort guests and residents — is carved into the coastline. Multiple dining venues round out the experience.

Siari joins Marriott International's ultra-luxury Ritz-Carlton Reserve collection, a deliberately small portfolio of lower-density resorts in remote, landscape-driven settings. The brand currently operates fewer than a dozen properties worldwide, each positioned at the top of the luxury market.

The opening adds to a wave of high-end development along Riviera Nayarit, which has attracted brands like One&Only, Four Seasons, and Conrad in recent years. For travelers who've been watching Cancun and the Riviera Maya absorb most of Mexico's resort investment, Siari is the strongest signal yet that the Pacific coast is staking its own claim in the luxury space.
