What is Pebble Beach?
Just below the Blue Point bridge, where the Bush Highway crosses the river on its way to Saguaro Lake, the Salt widens over a bar of water-rounded cobbles and the Tonto National Forest keeps a day-use area called, accurately, Pebble Beach. There are picnic tables and shade ramadas in the mesquite above the bar, vault toilets, a large dirt lot and a long gentle beach where it is easy to wade in and launch a tube, a kayak or a child. It sits about 20 miles northeast of Mesa, at about 1,400 feet, and it is the busiest put-in on the river.
Its character depends entirely on the calendar. From May through September, when the Salt River Project releases water from Saguaro Lake and the river runs cold and quick, this is the start of the classic two-to-three-hour float down past the Blue Point bluffs and the wild-horse meadows to Phon D Sutton or Coon Bluff. Thousands of people do it on a hot Saturday, the lot locks when full by mid-morning and the beach is coolers, speakers and sunburn. From October through April the releases drop, the river clears, the great blue herons come back and you can have a ramada and a quarter mile of beach to yourself. The upstream neighbor, Blue Point Day Use Area on the far side of the bridge, is a bigger beach with the same rules and the same pass.
What you get is the easiest access to moving water in the Valley, 40 minutes from Old Town on pavement, for the price of a Tonto Pass. What you do not get is camping, drinking water, quiet in summer, or a lot that stays open once it is full.
How to do Pebble Beach right
Buy the pass before you leave town. Every vehicle needs a Tonto Daily Pass on the dash: $8 bought ahead at a Forest Service office or a retail vendor (many East Valley gas stations and sporting-goods stores), $12 from the card machine on site. The $80 Tonto Discovery annual pass is honored, as are America the Beautiful passes at picnic sites. The Maricopa County Sheriff patrols the lot and checks. More on how the pass works is in the Tonto National Forest entry.
Get there. Loop 101 south to Loop 202 east, exit Power Road north, which becomes the Bush Highway (FR 204) in the forest. About 13 miles from the freeway, just before the bridge, turn left on Forest Road 169 at the Pebble Beach sign and follow the pavement a mile to the lot. The Phon D Sutton turnoff is also signed FR 169, four miles earlier; they are different roads. Figure 40 minutes from Old Town. Everything is paved; trailers and horses are not allowed in the site.
Arrive early or come in the off-season. On a summer weekend launch by nine or you will be parking on the Bush Highway shoulder, where the lot locks when full and the sheriff tows. From October to April the beach is nearly empty and the best picnic ground on the river.
Set the shuttle first. The float does not come back. Leave one car at Phon D Sutton or Coon Bluff, then drive the second to Pebble Beach. Only the commercial tube outfitter on the Bush Highway runs shuttles; the full routine, and the horse etiquette, is in our tubing guide.
Read the river. Check the Salt River Project’s release schedule before you go. At low summer releases the float takes nearly three hours and you will drag over the riffles below Blue Point; at high releases it is fast and pushy. The water comes out of the bottom of Saguaro Lake and is in the 60s even in July. Everyone wears a life jacket; the Forest Service warns that fallen trees in the channel trap swimmers every year. After any monsoon storm in the Mazatzals or over Saguaro Lake the river can rise fast; read the flash-flood basics and do not float on a storm day.
Water and rules. None to drink; bring it. Vault toilets only. No glass anywhere on the Lower Salt, enforced with tickets. Pack out everything.
Dogs. On leash on the beach. Many people float with dogs in the tube; the Forest Service does not prohibit it, but the water is cold and the wild horses on the banks do not like them.
Skip it if you want quiet in July. For a swim with less chaos drive another ten minutes to Butcher Jones on the lake. For a riverside picnic with the herons, come between October and April, when Pebble Beach is as good as the river gets.
A lumberman’s road to a dam, and the beach that came with it
The Salt River at Pebble Beach has been plumbing for a long time. A few miles downstream, where the river leaves the mountains and enters the Valley, the Hohokam built the largest canal system in prehistoric North America and ran it for a thousand years; the Akimel O’odham and Piipaash who farm the south bank today on the Salt River Pima-Maricopa reservation are their successors, and the Yavapai and Apache who held the canyon upstream are the people the Army fought for it in the 1870s. The river that reached all of them was wild: a flood in 1891 did enough damage to the Valley that the farmers organized, and the Salt River Valley Water Users’ Association and the federal Reclamation Act followed.
The Association’s first structure on this reach was not a storage dam but a diversion. Granite Reef Dam, finished in 1908 at the bottom of the canyon, turned the entire Salt into the Arizona Canal on the north bank and the South Canal on the other. Below it the riverbed went dry and has stayed dry except in floods. Above it, the 12 miles up to the mountains stayed a river by accident, because there was nothing to divert it into yet. Then came Stewart Mountain Dam, built between 1928 and 1930 five miles upstream as the last of the Salt’s four storage dams: a thin concrete arch 207 feet high that impounded Saguaro Lake and gave the Association a 13-megawatt power plant. From that year on, the water at Pebble Beach has come out of the bottom of a reservoir, cold in July, on a schedule set by irrigation orders and summer power demand. The float season exists because the Valley’s farms and air conditioners want water in June.
The road is the other half of the story. There was no good way up the river to the dam until Harvey Granville Bush, a Mesa lumberman, promoted one. Work on what was first called the Harvey Bush Highway began on March 21, 1933, and the road opened in 1934, climbing from Mesa through the saguaros to the dam and on toward Saguaro Lake. Where it crossed the Salt at Blue Point it put a bridge beside a wide cobble bar, and the bar beside the bridge became the obvious place to get in the water. The Bush Highway made the lower Salt the Valley’s river beach; before it, this reach belonged to ranchers and the occasional fisherman.
Tubing grew from a habit into an industry in the 1970s and 1980s, when a tube-rental and shuttle concession set up on the highway under Forest Service permit and the Tonto built Pebble Beach, Blue Point, Phon D Sutton and Coon Bluff into developed day-use sites to handle the weekends. The fee came in 1999, when the Tonto Pass was introduced to pay for the toilets, ramadas and trash pickup the crowds required. The herd came last to public attention: the free-roaming horses that graze the banks below the beach had been there for generations, descended by most accounts from ranch and mission stock, when in August 2015 the Forest Service announced it would round them up as stray livestock. The public reaction stopped the plan within days, and in May 2016 the state legislature passed the Salt River Horse Act protecting the herd; a management agreement with the Forest Service and a volunteer group followed, and the horses are now the river’s second attraction after the water.
What is coming is more of the same, managed harder: fuller lots, earlier gates, and the ongoing argument over how many horses the riparian cottonwoods can stand. The river’s flow still depends on how much snow fell on the White Mountains and how much Phoenix wants to drink.
Why it matters
Pebble Beach is where the Valley meets the river that built it. The Hohokam canals, the 1908 diversion dam, the 1930 storage dam and the 1934 road are all within a few miles of this cobble bar, and the cold water you float on in July is the direct product of all four. It is also the plainest lesson in how a free public beach works in Arizona: a Forest Service site, a pass to pay for the toilets, a sheriff for the gate, and a herd of horses protected by a law written in a hurry. For a Scottsdale visitor the verdict is simple. Forty minutes to moving water, two cars, a pass bought in town, life jackets on everyone, and October if you want the river to yourself.
