New Learn Page on the NWRS Webpage

The new “Learn” pages are live on the NWRS site — with links to puzzles, games, podcasts, stories, videos, webcams and coloring pages that kids and adults can do from home.

Virtual Learning

Even when you’re stuck indoors or keeping close to home, you can still deepen your knowledge of the natural world and entertain yourself in the process.

Fun reads, wildlife videos and webcams, nature puzzles and games, podcasts and coloring pages all can be good resources to inspire wonder and build nature knowledge at any age.

Browse our collection of lively resources from national wildlife refuges and fish hatcheries around the country on our new “Learn” pages.

New Visitor Parking at SR 94/Millar Ranch Rd

A new parking area to improve access to our trails!

parking lot diagram 512

The San Diego National Wildlife Refuge has been working with the Federal Highway Administration and the California Department of Transportation (Caltrans) to construct a 0.9-acre gravel-surfaced parking lot in an area to the east of the steel bridge and Sweetwater River, west of Millar Ranch Road, and south of State Route (SR) 94.
It is designed to accommodate approximately 43 vehicles, including five large-vehicle pull-through spaces and two Architectural Barriers Act (ABA)-compliant spaces. The new parking area will improve visitor access to the Refuge trail system, including the Sweetwater River Regional Trail, and support the Refuge’s current and future interpretive and environmental education programs.

Click Here for an enlarged map  

To ensure safe access from SR 94 into and out of the parking lot, several improvements will be implemented:

  • a new westbound, left-turn lane from SR 94 onto Millar Ranch Road;
  • lengthening and improving the existing eastbound, deceleration right-turn lane from SR 94 onto Millar Ranch Road; and
  • providing a new eastbound right-turn acceleration lane from Millar Ranch Road onto SR 94.

The project will be constructed with funding provided by Federal Lands Access Program (FLAP). The intent of FLAP is to improve transportation facilities that provide access to, are adjacent to, or are located within federal lands.
