Overview

The Interdune Boardwalk is the park’s easiest, most no‑stress way to slip into the gypsum dunes without trudging through sand. This elevated metal walkway skims a fragile interdune zone and ends at a dune overlook, with big views and bite‑size lessons about how this otherworldly landscape works. It’s perfect as a first stop to get your bearings or a mellow capstone at golden hour.

What You’ll See

You’re gliding over an interdune area—where hardy plants anchor the sand between dune ridges—so you’ll get a closer look at vegetation that helps shape the dunefield. Keep an eye out for movement along the edges; visitors regularly spot bleached earless lizards basking near the boardwalk. Views stretch across rippling white gypsum to the Sacramento Mountains.

Logistics & Amenities

Distance/time: about 0.4 miles round trip; plan 10–20 minutes at a relaxed pace.
Location: roughly 4.5 miles up Dunes Drive from the entrance station, directly off a parking lot.
On the route: multiple interpretive signs, benches, and a shaded canopy around the halfway point.
Trailhead: a decent‑sized (unpaved) parking area and two vault toilets; no potable water.
Dogs are welcome on a leash.
Stay on the walkway—this area is fragile, and leaving the boardwalk or sledding here is not allowed.

Best Time to Visit

Sunrise: soft light, cooler temps, and few people—great for photos.
Sunset: the dunes glow and shadows add texture; it’s a favorite for casual strolls and photography.
Full‑moon evenings are magical across the park; on select dates the park offers ranger‑led Moonlight Hikes (on another trail), so check the program schedule if that interests you.
Note: The boardwalk can be temporarily closed for safety. Verify status the day of your visit.

Is It Worth It?

Yes—especially for families, anyone easing into the dune field, or when you want education with your views. If you’re chasing the most dramatic, wide‑open dune panoramas, pair this with time deeper along Dunes Drive where the dunes feel bigger and wilder.

Tips

Midday glare on white sand is intense—bring sunglasses, a hat, and water.
Arrive near sunrise or an hour before sunset for the best light and fewer people.
If you continue farther along Dunes Drive, expect some washboarded sections; take it slow.
There’s no drinking water at the boardwalk—fill up before you head out.
Check the park’s current conditions the day you visit; closures do happen.
