You’re driving through the high desert of Arizona, dodging the heat of Phoenix, and suddenly the air starts to smell like pine needles and damp earth. Most people hitting Prescott for the first time head straight for Watson Lake. I get it. Those giant granite dells look like something out of a sci-fi movie. But if you want to actually relax? You keep driving. You wind your way up Senator Highway, past the historic downtown, until the road gets a bit twisty and the shadows get longer. That’s where you find it. Goldwater Lake Prescott AZ isn't just another reservoir; it's the place where the locals go when they want to escape the "tourist" side of town.
It’s quiet here. Usually.
The lake is nestled at about 5,600 feet, which means it stays significantly cooler than the valley below. While people in Scottsdale are melting in 110-degree heat, you're probably sitting under a Ponderosa pine in a comfortable 85 degrees. It’s a literal lifesaver. Honestly, the first time I saw the water peeking through the trees, I didn't think I was in Arizona anymore. It feels more like the Pacific Northwest or maybe a quiet corner of Colorado.
The Reality of Getting on the Water
Let’s talk about the water because that’s why you’re here. Goldwater Lake is basically two lakes—Upper and Lower—though the upper one is where all the action is. And by "action," I mean people paddling slowly in circles.
You cannot use gas motors here. Period.
That is the single best rule the City of Prescott ever implemented for this spot. Because there are no jet skis screaming past or wake boats churning up the mud, the surface stays like glass most mornings. It’s a haven for kayakers and paddleboarders. If you don't own a boat, don't sweat it. During the season, which usually kicks off in May, Prescott Outdoors sets up shop right on the shore. They rent out kayaks and canoes by the hour. It’s pretty seamless. You show up, sign a waiver, and you’re drifting away from your problems ten minutes later.
Fishing is the other big draw. The Arizona Game and Fish Department keeps this place stocked with rainbow trout. You’ll also find largemouth bass, channel catfish, and some sunfish if you’re lucky. I’ve seen kids pull out trout that were surprisingly decent-sized, though most are your standard "pan-fry" variety. Just remember you need a valid Arizona fishing license. Don't be that person who gets a ticket because they thought "it's just a small lake." The rangers do check.

Hiking the Goldwater Lake Prescott AZ Trail System
If you aren't a "water person," the dirt is just as good.
The main loop around the lake is easy. It’s mostly flat, family-friendly, and offers great views of the dam. But if you want to actually sweat, you need to look for the Goldwater Lakes Trail #396. This trail is part of the massive Prescott Circle Trail system. It’s roughly 8 miles if you do the whole section, connecting Goldwater to White Spar Campground.
The terrain is classic Prescott: decomposed granite, pine duff, and the occasional steep switchback. It’s shared with mountain bikers, so keep your ears open. Those guys come flying down the hills sometimes. Honestly, the best part of the #396 is the transition. You start in the dense forest near the lake and eventually break out into these higher ridges where you can see the San Francisco Peaks on a clear day.
What to Pack for the Trails
- Water: More than you think. The altitude dries you out before you realize you’re thirsty.
- Layers: Even in July, a cloud cover can drop the temp by ten degrees in minutes.
- Sturdy shoes: This isn't a flip-flop hike. The granite is slippery.
The "Lower" Secret
Most people never even see Lower Goldwater Lake. It’s tucked away, smaller, and honestly a bit more rugged. It’s not meant for the big picnic crowds. While the Upper Lake has the sand volleyball court, the horseshoe pits, and the massive ramadas that people reserve months in advance for weddings and reunions, the Lower Lake is for the solitary types.
I’ve spent mornings there just watching the ospreys hunt. If you’re a birdwatcher, this is your spot. You’ll see bald eagles occasionally, especially in the winter months. It’s a much more "raw" experience compared to the manicured grass and paved parking lots of the main park area.
Costs, Rules, and The Stuff Nobody Tells You
Parking isn't free. Well, it is on Wednesdays, which is a nice "Free Dead Day" tradition in Prescott. Otherwise, it’s $3.00 per vehicle. That’s a bargain. Compare that to the $15 or $20 you’ll pay at some state parks and it’s basically a gift.

Here’s the thing about the "No Swimming" rule. It’s strictly enforced. People get annoyed because the water looks so inviting, but Goldwater is a primary water source for the city. They want to keep the human bacteria and sunscreen out of the drinking supply. Respect it. If you absolutely have to submerge your body in water, head over to Lynx Lake or drive down to the Verde River. If you try to swim here, a ranger will be on you faster than a seagull on a dropped fry.
Speaking of fries, there isn't a concession stand. Bring your own food. There are plenty of charcoal grills scattered around the picnic areas. On a Saturday in June, the smell of burgers and pine trees is basically the official scent of Goldwater Lake.
A Note on Accessibility
The City of Prescott has actually done a decent job making the main areas accessible. There are paved paths near the primary ramadas and the boat launch area. It’s not a wilderness trek just to get to a picnic table, which makes it a great spot for multi-generational families. My grandmother could sit by the water and watch the grandkids play without having to scramble over boulders.
Why This Lake Beats Watson and Willow
Don't get me wrong, I love the Granite Dells. They are iconic. But Watson and Willow Lakes are "exposed." There is almost zero shade. If you go there in the middle of a July afternoon, you are going to bake.
Goldwater Lake Prescott AZ offers a canopy. The trees are huge. The wind whistles through the needles in a way that sounds like the ocean. It feels secluded, even though you’re only about 15 minutes from the Courthouse Plaza.
Also, the wind. Watson Lake can get incredibly choppy because it’s so open. It can be a real struggle to paddle back to the docks if the wind picks up. Goldwater is much more protected. It’s a "softer" environment. It’s the difference between an epic mountain adventure and a cozy afternoon in the woods.

The Best Time to Visit
Autumn. Without a doubt.
While Arizona isn't exactly Vermont, the Gambel oaks around the lake turn a brilliant gold and orange. The contrast between the blue water, the green pines, and the fiery oaks is stunning. The crowds thin out once school starts, and you can often have the hiking trails entirely to yourself.
Winter is also surprisingly beautiful. The lake doesn't always freeze solid, but it gets a thin skin of ice around the edges. Seeing the Ponderosas dusted in snow with the dark water in the center is like living inside a postcard. Just check the road conditions on Senator Highway before you go; it can get icy and the city doesn't always plow it immediately.
Actionable Steps for Your Trip
To make the most of your visit to Goldwater Lake, you need a plan that goes beyond just showing up.
- Arrive early on weekends: The parking lot fills up by 10:00 AM on Saturdays. If the "Lot Full" sign is out, they won't let you in until someone leaves.
- Download the Avenza Map: Specifically, look for the Prescott National Forest maps. Cell service can be spotty once you get into the deeper ravines on Trail #396.
- Check the Prescott City website for blue-green algae alerts: Like many Arizona lakes, Goldwater can sometimes have blooms during the hottest months. It usually doesn't affect boating, but it's good to know for your dogs.
- Bring $3 in cash: While there are pay stations that take cards, they are notoriously finicky in the cold or high humidity. Having exact change for the envelope saves a lot of swearing.
- Secure your trash: There are plenty of bins, but the local ravens and raccoons are geniuses. If you leave a bag of chips on a picnic table to go for a 5-minute walk, it will be gone when you get back.
Goldwater Lake remains one of the few places in Yavapai County where you can truly find a moment of stillness. It isn't flashy, and it doesn't have the dramatic rock formations of its neighbors, but it has heart. It’s the kind of place that reminds you why people fell in love with the American West in the first place—the scale, the silence, and the simple pleasure of a cool breeze on a hot day.
