About a mile up Rancho San Carlos Road from Carmel Valley Road, a stone gatehouse marks the entry to the Santa Lucia Preserve, open to owners, their guests and staff. Past it are roughly 31 square miles of redwood canyons, oak grassland and ridgetops, nearly 100 miles of trails, and 297 homesites.
The number that defines the place is not the homesite count. It is 18,000. Of the Preserve's 20,000 acres, 18,000 are protected in perpetuity and managed by the Santa Lucia Conservancy, leaving about 10 percent for homesites, roads, infrastructure and club amenities. Buyers here are buying into that ratio, and into the rules that keep it.
The land combined two Mexican-era grants, and a Rumsen Ohlone village called Echilat once stood within the present Preserve. George Gordon Moore bought it in 1924, renamed it Rancho San Carlos and built the Hacienda and Moore's Lake. The Oppenheimer family ran cattle here for about 50 years before selling in 1990, and the Conservancy was incorporated in 1995 as a land trust funded by an endowment from the original homesite sales. The Hacienda, a 1920s Spanish-style building with 37 rooms, now serves as a private inn for members and their guests.
Every homesite came with a building envelope chosen in advance, and the Design Review Board applies guidelines it wrote with the Conservancy so that homes stay largely out of view from roads and trails. Privately owned Openlands, roughly 7,650 to 8,000 acres under Conservancy easements, prohibit structures, landscaping, parking and water development, and native vegetation there can be removed only with written Conservancy approval.
Services are local. The Santa Lucia Community Services District runs water, wastewater, roads, refuse and gate control, drawing drinking water from 36 wells through five treatment facilities and serving 202 active connections. Water is billed in tiers, from $2.04 per 1,000 gallons for the first 5,000 gallons up to $16.33 above 20,000. The district is also preparing a Mello-Roos special tax election to fund road repairs, so ask for current assessments alongside association dues.
Ranch Club amenities include the Hacienda, an equestrian center with two arenas and access to 44 groomed trails, a sports center, a swim center, three dining venues and Moore's Lake. The Preserve Golf Club, a private Tom Fazio design on 365 acres, is open to Preserve and national members. The trail system reaches Moore's Lake, Peñon Peak and the redwood groves, and 42 miles of private paved roads double as cycling routes. Four creeks, Las Garzas, Potrero, San Jose and San Clemente, run from the Preserve to the Carmel River, and biologists surveyed steelhead in San Jose Creek in July 2026. Monterey Regional Airport is about 15 minutes from the main gate, and the Preserve puts Carmel-by-the-Sea about 10 minutes away.
What does it cost to buy in?
In October 2026, the Preserve's own listings showed homesites asking roughly $350,000 to $1.3 million and homes asking roughly $5.25 million to $13.3 million, with the homes ranging from about 4,000 to 7,900 square feet on 3.9 to 46 acres. Those are small samples, and the site itself notes its listing data may not be current.
Can I build anywhere on my lot?
No. Each homesite has a pre-sited building envelope, plans go to the Design Review Board, and privately owned Openlands under conservation easement cannot hold structures at all.
Where does the water come from?
From the Preserve's own groundwater. The community services district operates 36 wells feeding the drinking water system through five primary treatment facilities, with a separate set of wells for golf course irrigation.
Does buying include golf?
Golf is a separate decision. The Preserve Golf Club is private and open to Preserve and national members, so confirm membership terms directly with the club alongside the purchase.
