16th Avenue Tiled Steps: A Mosaic Ascent in the Sunset District
San Francisco, California, United States
This 163-step masterpiece transforms a standard neighborhood incline into a shimmering mosaic river that flows from the sea to the sun, doubling as a vital ecological corridor for rare local butterflies.

Hidden within the fog-brushed residential streets of San Francisco’s Sunset District, a mundane concrete thoroughfare has been reborn as a sprawling, vertical canvas. The 16th Avenue Tiled Steps consist of 163 individual risers, each meticulously adorned with vibrant mosaics that tell a story of the natural world.
While the surrounding neighborhood is famously quiet, this specific hillside has become a pilgrimage site for those seeking a blend of public art and panoramic vistas.
Why It Stands Out
The project is a testament to community spirit and artistic vision, spearheaded by artists Aileen Barr and Collette Crutcher. Inspired by the world-famous Selarón staircase in Rio de Janeiro, the duo worked with neighborhood volunteers between 2003 and 2005 to install thousands of donated tiles.
The design follows a cohesive narrative arc: as you ascend, the imagery transitions from the depths of the ocean at "sea level" to the celestial heights of the sun at the summit. Beyond its aesthetic appeal, the staircase serves a critical environmental purpose.
The surrounding gardens are meticulously planted with succulents and native flora designed to support the Green Hairstreak butterfly. This site is a key link in the Green Hairstreak Corridor, an urban conservation effort to provide habitat for this iridescent local species.
At the very top, visitors are treated to more than just a view; the peak features a unique biozone containing some of the city's last remaining Franciscan formation rock outcroppings.
Before You Go
The staircase is located at 16th Avenue and Moraga Street. It is a steep climb, but the reward at the top is one of the most expansive views of the city and the Pacific Ocean.
Because this is a quiet residential area, visitors should be mindful of noise levels and local parking. The gardens are maintained by volunteers, so staying on the designated paths is essential to protect the delicate butterfly habitat.
