Ponderosa Pine Scenic Byway: Drive Into the Heart of the Gem State

Ponderosa Pine Scenic Byway is a beautiful drive that takes motorists from Idaho’s capital city Boise into the heart of the Gem State. The route passes through several national forests and is nothing short of breathtaking!

The journey from Boise to Stanley on Highway 21 is almost as good as the final destination. On this road trip you’ll travel through forests thick with ponderosa pines and alongside sparkling rivers. All while craggy mountaintops stay front and center through the car windscreen.

Begin this road trip in Boise, the state’s capital, where you’ll find a vibrant downtown with a booming craft brew and culinary scene, along with handsome historic buildings.

Highway 21 connects Boise to Idaho City through Boise National Forest, a heavily forested route that runs alongside Mores Creek. In summer you’ll likely be tempted to cool off in the creek and fortunately there are several places you can pull over to do so.

Once in Idaho City, spend an hour or two getting to know this ghost town’s glorious mining history before continuing your drive. From Idaho City the byway meanders up to Lowman, a charming homesteading community situated on the banks of the Payette River.

Lowman is the perfect place to go off-grid; there are plenty of free primitive campgrounds, natural hot springs, and numerous spots to jump in crystal clear rivers and creeks.

Between Lowman and Stanley is some of the most stunning natural scenery in Idaho. The byway squeezes between two of Idaho’s wilderness areas; on the right is the Sawtooth Wilderness Area and to the left is Salmon-Challis National Forest. Access roads to the north along this stretch will take you into the Frank Church River of No Return Wilderness.

The road trip ends in Stanley, a mountain town that sits at the base of the Sawtooth Mountains that is packed with outdoor adventure!

While the drive between Boise and Stanley on Highway 21 takes approximately three hours to complete, it’s worth taking the extra time to enjoy the ride and really savour the scenery. Here’s a guide to all of the best stops on Ponderosa Pine Scenic Byway.

Best Stops on Ponderosa Pine Scenic Byway

Lucky Peak State Park

Lucky Peak State Park, which is only a ten minute drive from downtown Boise, is the first stop on this Idaho road trip. This state park in Idaho offers Idahoans and visitors to the Gem State a place to picnic, swim, boat, and fish.

There are three distinct units that make up Lucky Peak State Park; Sandy Point, Discovery Park, and Spring Shores.

Sandy Point is the best place to head in summer near Boise for fun in the sun! You’ll find a sandy beach here perfect for lazing about and sunbathing, along with a large lake to cool off, complete with water toys.

Discovery Park is an area popular with canoeists and kayakers for having calm waters to paddle on. It’s also a good spot of birdwatching where waterfowl congregate in summer and bald eagles are commonly seen here in winter.  

Spring Shores is situated on the shore of Lucky Peak Lake. There is a full-service marina here, a convenience store, marina supplies, and recreation equipment rentals.

Idaho City

Idaho City was once a thriving trading post for gold miners. In fact, business was so prosperous here during the 1860s that Idaho City was the largest town in the Northwest — even bigger than Portland, Oregon!

When the mining dried up, the town’s population declined to just 104 people, giving rise to Idaho City’s reputation as a ghost town. Today, you can walk through the historic downtown area on creaky boardwalks and see preserved wooden buildings including an old county jail.

Since there are now about 500 residents living here, Idaho City is not technically a ghost town although it still very much has a creepy ghost town feel about the place.

Idaho City is nestled in the Boise Basin which is home to miles of hiking trails in the summer that become snowshoe and cross-country skiing trails in winter.

Kirkham Hot Springs

Imagine soaking in steaming geothermal pools surrounded by mountains on all sides while listening to a rushing river. Well you can do just that on this Idaho road trip!

Kirkham Hot Springs is situated right on the banks of the South Fork Payette River. There are multiple natural pools here of varying temperatures and sizes. The largest of the pools has a beautiful, boiling hot waterfall cascading over rocks into it that you can stand under.

You can find Kirkham Hot Springs right off Ponderosa Pine Scenic Byway. From the parking lot a trail leads down to multiple soaking pools along the river’s edge. Be careful walking over the rocks as they can be slippery when wet.

Kirkham Hot Springs is open for day use only from 7am to 9pm. Dogs are allowed here but must be kept leashed and away from all hot spring pools and runoff areas.

Lowman

Lowman is a very small community situated on the banks of the Payette River. It is a geothermally active region and as a result there are multiple hot springs in the area, some well-known and others hidden in the surrounding mountains.

This is a great place to escape for a few days and go totally off grid as there are multiple areas that allow for dispersed camping along Highway 21 in Lowman. Just know it is all primitive camping on BLM land. Please pack out whatever you pack in!

There are two motels if you want to stay in Lowman but prefer not to camp; the Sourdough Lodge and Southfork Lodge.

The Sourdough Lodge has a full service restaurant open year-round for breakfast, lunch and dinner, serving hearty portions including the local’s favorite sourdough pancakes. There is also a convenience store here selling groceries, camping supplies, and fishing gear.

If you plan to just drive through, the trip between Lowman and the final stop in Stanley is exceptional. From here on out you’ll be driving between the Sawtooth Wilderness Area on one side of the road and the Frank Church River of No Return Wilderness Area on the other. At 2.3 million acres, the latter has more acres of road-less wilderness than anywhere else in the lower forty-eight states!

Stanley Lake

Stanley Lake is one of the most beautiful lakes in Idaho. This stunning alpine lake is situated in a valley beneath the iconic Sawtooth Mountain Range. Towering at the northern end of the lake at 9,860 feet is the awe-inspiring McGowan Peak which provides a dramatic backdrop.

The lake is a fantastic place to visit for photographers looking to capture Central Idaho’s stunning scenery. If you’re looking for somewhere to expend some energy there are several hiking trails that begin here including a popular hiking trail to Lady Face Falls.

Besides hiking you can go kayaking, paddle boarding, boating and swimming at Stanley Lake. The lake is stocked with rainbow, cutthroat and bull trout and a great place to fish.

There is a campground with 19 campsites set among a thick grove of lodgepole pine trees overlooking the lake. Most of the sites have mountain and lake views. Vault toilets and potable water is available. A boat ramp is located nearby. You can reserve campsites at Stanley Lake here.

Stanley Lake is located inside Sawtooth National Recreation Area about eight miles west of Stanley, Idaho. From Ponderosa Pine Scenic Byway (Highway 21) there is a three mile gravel road that leads to the lake. The area is accessible year round but snow may limit vehicle access during winter.

Stanley

Stanley, Idaho is one of the most picturesque towns in America! This teeny tiny mountain town situated at the base of the iconic Sawtooth Mountain Range is a mecca for adventure seekers.

There are limitless outdoor recreation opportunities for everyone here from hiking to mountain biking, horse riding, paddle boarding, whitewater rafting, fly-fishing, finding hot springs, and so much more!

At Stanley’s doorstep is the Sawtooth Mountain National Recreation Area, a wilderness paradise home to countless peaks, mountain meadows, and sparkling lakes.

Some of the most beautiful lakes you can hike to in the Sawtooth Mountains is Goat Lake and Sawtooth Lake. If you’re a hiker and have time, the hike to both of these lakes should be on your Stanley bucket list.

However if you’d prefer to unwind at the end of this road trip, book a stay at Mountain Village Lodge and take advantage of their exclusive hot spring which is for guests only. It has unbelievable views of the Sawtooth Mountains!

Stanley is located at the intersection of Highway 21 and Highway 75, and the last stop on this Ponderosa Pine Scenic Byway road trip. You can drive back to Boise the same way you came or loop back around on Sawtooth Scenic Byway.

For those of you heading north to Montana or Glacier National Park, you can take Salmon River Scenic Byway all the way up to Missoula.

When is the best time to visit Central Idaho?

If you’re looking forward to outdoor adventure, summer is the best time of year to visit Central Idaho due to longer daylight hours and less chance of rain. Spring and autumn can be a good time to visit too if you prefer to avoid peak tourist season but keep in mind there is greater chance of snowfall in May, June, and October.

Winter in Central Idaho can be brutal but still beautiful. While a portion of Highway 21 between Boise and Lowman remains open year-round, the stretch of highway between Lowman and Stanley usually closes some time in November and re-opens around April.
