Responsible Stewards Of The Land

Since opening our doors in 1992, Post Ranch has been at the forefront of environmental responsibility and continues to be an industry leader when it comes to sustainability. It is our belief that what’s good for the planet can also be good for your guest experience.

Design & Architecture

Post Ranch’s innovative organic environmental design was intended for people to feel a part of nature rather than observers. Designers used bio-structure architecture, utilizing the natural materials of glass, wood, stone, and passive solar heat.

  • Efforts were made to avoid cutting trees when the property was developed.
  • The earth-sheltered Ocean Houses with sod roofs blend into the landscape and reduce heat loss.
  • The stilted 9 ft. Tree Houses were designed to protect the fragile root balls of nearby redwood and oak trees.
  • Reclaimed wood, including old-growth redwood from old wine casks, adds a rich, deep red color to many guestroom walls.
  • Trees that fall on the property are retrieved and made into benches along the pathways.

Natural Resources

Because we try to live our values, we’ve developed processes and systems that make the most of natural resources. While we know we aren’t perfect, our aim is always zero-to-minimal impact.

  • Post Ranch Inn created the first commercial greywater system approved in Monterey County.
  • All water used at Post Ranch Inn is sourced and treated via the seven wells located on property. That includes drinking water, water used in guestrooms, Sierra Mar, maintenance, laundry, etc. 
  • Usage is measured daily and quality is monitored and tested weekly.
  • Water-efficient landscaping is used, focusing on native and drought-tolerant plants that are tended with organic fertilizer.
  • Single-use plastic bottles and styrofoam are not used anywhere on the property.
  • Post Ranch follows an extensive, property-wide recycling program for paper, newspaper, cardboard, cans, glass, aluminum, and compost from the restaurant. Also, to minimize waste and packaging, we use and produce recycled and recyclable materials.
Solar panels at Post Ranch Inn


In 2009, Post Ranch switched on a 990-panel solar installation. According to the EPA, the installation is estimated to reduce carbon emissions by approximately 600,000 pounds annually. That’s just one way the Post Ranch is working to conserve and practice clean-energy.

  • The solar power generation consists of 990, 210-watt photovoltaic (light to electricity) solar panels that produce almost 350,000 kWh of pollution-free electricity per year.
  • LED and low-voltage lighting are used throughout the property.
  • South-facing windows in guestrooms have been tinted to lower energy use.
  • A protective film has been placed on ocean-facing windows to reduce the sun's harmful effects, maintain room comfort, and save energy.
  • Guests are transported in fuel-efficient Lexus hybrid vehicles. Guests' vehicles are parked away from the hotel rooms, avoiding traffic and emissions, and ensuring a serene environment.

Land & Wildlife

To preserve this pristine land and the wildlife that call it home, 90 of our 100 acres are maintained as a protected area, with the goal of zero impact and land preservation.

  • The land is home to a number of indigenous species, including several that are rare, endangered, or threatened such as the Smith's blue butterfly (SBB), California red-legged frog (CRLF), California condor. To ensure these species continue to flourish, an extensive program of activities is in effect that includes conservation, site management, habitat protection and enhancement and guest education.
  • An ongoing habitat conservation plan discourages invasive non-native flora and fauna.
  • Forest management is an ongoing project designed to maintain healthy woodlands and protect flora and fauna.
  • Post Ranch is active in the identification of Sudden Oak Death and fully participates in efforts to remove diseased trees, while planting a new oak tree for each that succumbs. 
  • Over 150 redwood and oak trees and other landscaping have been added, providing privacy, wind protection, shade, and beauty.
  • Plant waste is chipped, mulched, and returned to the earth. 
  • No chemical pesticides or herbicides are used on the property.

We’re only as strong as the community around us. Post Ranch has always made a strong effort to support the local Big Sur community both socially and economically.
