Tucked away on a scenic loop with minimal through traffic, this property feels worlds away from the city. Mature trees, peaceful surroundings, and breathtaking views create a tranquil setting, yet everyday conveniences-including H-E-B at the bottom of the hill-are just moments away. The property features a one-year-old roof and an approximately 264-square-foot detached, fully climate-controlled office/flex space, perfect for a home office, studio, gym, hobby room, or whatever best fits your lifestyle. Recent improvements include an electric automatic entry gate with solar power and battery backup, a water softener system, and a reverse osmosis water filtration system. These are just a few of the many updates made to the property (please see Associated Documents for a complete list of improvements). Whether you're dreaming of a private retreat, a place to spread out, or simply a peaceful setting, this property is ready for its next chapter. Experience the best of both worlds-peaceful Hill Country living with all the conveniences of city life just minutes away. ## Location - **Address:** 21509 MONARCH PASS, San Antonio, TX 78255 - **County:** Bexar - **Coordinates:** 29.642216, -98.658435 - **Google Maps:** https://www.google.com/maps?q=29.642216,-98.658435 ## Listing Agent - **Name:** Hayley Shalley - **Brokerage:** Kerri Real Estate - **Phone:** (210) 272-7887 - **Broker Phone:** (210) 272-7887 - **Listing URL:** [View original listing](https://www.realtor.com/realestateandhomes-detail/21509-Monarch-Pass_San-Antonio_TX_78255_M80305-06432?f=listhub&s=SABORTX&m=1992406&c=propsimple) ## Photos ![21509 MONARCH PASS - Photo 1](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f96592593r.jpg) ![21509 MONARCH PASS - Photo 2](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f2108086211r.jpg) ![21509 MONARCH PASS - Photo 3](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f1791157783r.jpg) ![21509 MONARCH PASS - Photo 4](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f3692698842r.jpg) ![21509 MONARCH PASS - Photo 5](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f3440657915r.jpg) ![21509 MONARCH PASS - Photo 6](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f2904364391r.jpg) ![21509 MONARCH PASS - Photo 7](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f3753809493r.jpg) ![21509 MONARCH PASS - Photo 8](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f335744807r.jpg) ![21509 MONARCH PASS - Photo 9](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f1398588722r.jpg) ![21509 MONARCH PASS - Photo 10](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f1827050150r.jpg) ![21509 MONARCH PASS - Photo 11](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f638489334r.jpg) ![21509 MONARCH PASS - Photo 12](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f2314552337r.jpg) ![21509 MONARCH PASS - Photo 13](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f1272874278r.jpg) ![21509 MONARCH PASS - Photo 14](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f1929270641r.jpg) ![21509 MONARCH PASS - Photo 15](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f15241369r.jpg) ![21509 MONARCH PASS - Photo 16](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f1772827503r.jpg) ![21509 MONARCH PASS - Photo 17](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f1964451641r.jpg) ![21509 MONARCH PASS - Photo 18](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f3679059178r.jpg) ![21509 MONARCH PASS - Photo 19](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f2877318617r.jpg) ![21509 MONARCH PASS - Photo 20](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f1845012337r.jpg) ![21509 MONARCH PASS - Photo 21](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f4121153113r.jpg) ![21509 MONARCH PASS - Photo 22](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f2187203946r.jpg) ![21509 MONARCH PASS - Photo 23](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f1926329856r.jpg) ![21509 MONARCH PASS - Photo 24](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f2270934612r.jpg) ![21509 MONARCH PASS - Photo 25](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f1548271471r.jpg) ![21509 MONARCH PASS - Photo 26](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f1330779490r.jpg) ![21509 MONARCH PASS - Photo 27](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f2881740699r.jpg) ![21509 MONARCH PASS - Photo 28](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f3846034937r.jpg) ![21509 MONARCH PASS - Photo 29](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f3580245881r.jpg) ![21509 MONARCH PASS - Photo 30](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f2692902386r.jpg) ![21509 MONARCH PASS - Photo 31](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f2208487932r.jpg) ![21509 MONARCH PASS - Photo 32](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f1182194039r.jpg) ![21509 MONARCH PASS - Photo 33](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f1345051121r.jpg) ![21509 MONARCH PASS - Photo 34](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f3566794859r.jpg) ![21509 MONARCH PASS - Photo 35](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f2986054242r.jpg) ![21509 MONARCH PASS - Photo 36](http://lh.rdcpix.com/ba28e5d082094382e365963101046284l-f2992211959r.jpg) --- **MLS#:** 1992406 | **Updated:** 2026-09-22 **Source:** listhub *Copyright © 2026 LERA MLS.
