Overview
Sun Lakes–Dry Falls State Park occupies a sweeping stretch of the Columbia Plateau in Grant County, eastern Washington, roughly 80 miles southwest of Spokane and about 90 miles east of Wenatchee. The park sits at the heart of the channeled scablands, a landscape violently sculpted by the Missoula Floods — a series of catastrophic ice-age megafloods that repeatedly tore across the Pacific Northwest between roughly 13,000 and 15,000 years ago.
The park's defining feature is Dry Falls, a horseshoe-shaped cliff nearly 400 feet tall and about 3.5 miles wide. During the floods, this was one of the largest waterfalls in Earth's geological history — dwarfing Niagara in both height and volume. Today the cliff stands silent above a series of calm desert lakes, making it one of the most visually dramatic geological sites in North America.
The surrounding Sun Lakes area includes a chain of lakes — Park Lake, Dry Falls Lake, Lake Lenore, and others — nested inside the Grand Coulee, offering swimming, kayaking, fishing, and birdwatching against a backdrop of towering basalt walls. Wildlife including mule deer, coyotes, waterfowl, and raptors are commonly observed throughout the park.
Before You Go
Discover Pass
Access to Washington State Parks requires a Discover Pass for most vehicles. Passes can be purchased online through the Washington State Parks website, at park self-pay stations, or at many licensed vendors. Day passes and annual passes are available — verify current pricing on the official site before your visit.
Climate
Eastern Washington east of the Cascades has a semi-arid, high-desert climate. Summers (June–August) are hot and dry, with temperatures regularly exceeding 90°F (32°C). Spring and fall are cooler and more comfortable for hiking. Winters are cold and can bring snow; check road and park conditions before visiting between November and March.
What to Pack
- Ample water — shade is scarce and heat can be intense in summer
- Sun protection: hat, sunscreen, sunglasses
- Sturdy footwear for rocky basalt terrain
- Binoculars for wildlife and birdwatching
- Layered clothing for cool mornings and evenings in spring/fall
Connectivity
Cell service in the coulee can be limited. Download offline maps and park information before arriving.
Getting There
By Car
The park is most practically reached by private vehicle. From Spokane, take US-2 west to Coulee City, then head south on WA-17 — approximately 80 miles. From the Tri-Cities or Yakima, travel north on US-395 and connect via WA-17 north. The park entrance and Dry Falls Visitor Center are clearly signed along WA-17 and US-2 near Coulee City.
By Air
The nearest commercial airports are Spokane International Airport (GEG), roughly 80 miles to the east, and Pangborn Memorial Airport in Wenatchee (EAT), approximately 90 miles to the west. Both require a rental car to complete the journey to the park.
Public Transit
No scheduled public transit serves the park directly. Visitors without personal vehicles should plan on renting a car from one of the regional airports or nearby cities.
Getting Around
A personal vehicle is essential for getting around the park and surrounding area. The park encompasses multiple distinct units spread along several miles of WA-17 and US-2 — the Dry Falls Visitor Center, Sun Lakes resort area, Park Lake, Dry Falls Lake, and Lake Lenore are all separate stops that are impractical to walk between.
Within individual day-use areas, short foot trails and viewing paths are manageable on foot. The Dry Falls overlook trail from the visitor center is short and paved in sections but involves uneven surfaces. Trails along the lake edges and coulee walls are generally informal and can be rocky; no technical equipment is required.
Boating on park lakes — non-motorized and some motorized — is permitted. Kayaks, canoes, and small fishing boats can be launched from designated areas. Verify current boating regulations and any seasonal restrictions on the Washington State Parks website before your visit.
Where to Stay
Camping
Sun Lakes–Dry Falls State Park offers developed campgrounds with standard and utility (electric/water) hookup sites, as well as tent-only areas. Restrooms, showers, and picnic areas are available in the main campground. Reservations are strongly recommended for summer weekends and can be made through the Washington State Parks reservation system. Verify availability and current fees on the official site.
Sun Lakes Park Resort
A privately operated resort adjacent to the state park offers cabin rentals, RV sites, boat rentals, and a small store. This is a convenient option for visitors who want amenities without commuting far. Contact the resort directly for current availability and pricing, as it operates independently of the state park.
Nearby Towns
Coulee City (approximately 5 miles north on US-2) and Electric City/Grand Coulee (roughly 25 miles north) have motels and small hotels. These serve as practical bases, especially if the park campground is full. Verify accommodations and availability locally or through standard booking platforms.
Things to See & Do
Dry Falls Overlook and Visitor Center
The Dry Falls Interpretive Center (operated by Washington State Parks) sits at the rim of the ancient falls and offers exhibits explaining the Missoula Floods geology in accessible detail. The overlook provides one of the park's most memorable views — a panorama of the basalt amphitheater and the lakes below. Check current visitor center hours on the official Washington State Parks site before visiting, as seasonal schedules vary.
Fishing
The park lakes — including Dry Falls Lake, Park Lake, and Lake Lenore — support populations of rainbow trout and other species. Lake Lenore is designated a catch-and-release lake for large-strain Lahontan cutthroat trout, a special draw for fly-fishing enthusiasts. A valid Washington State fishing license is required; verify current rules and season dates with the Washington Department of Fish and Wildlife.
Hiking
Trails range from the short paved path at the Dry Falls overlook to longer informal routes along the coulee floor and lake shores. The basalt cliffs and talus slopes reward explorers, though trails are not extensively developed — bring a map and wear sturdy shoes.
Swimming and Water Recreation
Park Lake and other designated areas offer swimming in summer. Non-motorized watercraft are welcome on most lakes. Kayaking along the cliff-lined shores of the coulee is a scenic and popular activity.
Birdwatching
The park and adjacent Lake Lenore area attract a variety of raptors, waterfowl, and songbirds. White pelicans, Canada geese, hawks, and eagles are among the species regularly spotted. Birding is particularly rewarding during spring and fall migration.
Stargazing
The park's remote location and low light pollution make it a good spot for stargazing. Clear summer nights often reveal the Milky Way.
Food & Drink
There are no restaurants or cafes inside the state park itself. Sun Lakes Park Resort operates a small convenience store that carries basic supplies and snacks — verify hours and current offerings directly with the resort.
Coulee City, about 5 miles north on US-2, has a small number of local diners and a grocery store where you can stock up on food and water. Electric City and Grand Coulee, roughly 25 miles north, have a broader selection of restaurants and grocery options.
Most campers and day visitors plan ahead and bring their own food, coolers, and drinking water. Picnic areas with tables and fire grates are available throughout the park. Campfires may be subject to seasonal burn bans — check current fire restrictions with the park or Washington State Parks before your visit.
Practical Information
Emergency Services
For emergencies, dial 911. The nearest hospitals are in Ephrata (Grant County Hospital) and Moses Lake, both roughly 30–40 miles from the park. Cell service can be unreliable inside the coulee — take note of this when planning solo activities.
Park Fees
A Discover Pass is required for day-use parking. Campground fees are separate. Check current rates on the Washington State Parks website as fees are subject to change.
Pets
Leashed pets are generally permitted in day-use areas and campgrounds. Pets are typically not allowed on swimming beaches or inside park buildings. Verify current pet policies on the official park page.
Accessibility
The Dry Falls overlook area and visitor center have paved and accessible paths. Other areas of the park involve uneven terrain. Contact Washington State Parks for detailed accessibility information for specific sites.
Leave No Trace
The basalt ecosystem is fragile. Stay on designated paths, pack out all waste, and do not disturb the geology or wildlife. Ground squirrels and other wildlife at the overlook are accustomed to visitors — do not feed them.
Safety
Heat is the primary hazard in summer. Temperatures above 95°F (35°C) are common in July and August. Carry significantly more water than you think you need — at least one liter per person per hour of hiking in hot conditions — and avoid strenuous activity in the middle of the day.
The basalt terrain can be slippery and sharp, particularly around the cliff edges and talus slopes near the coulee walls. Stay well back from the rim at the Dry Falls overlook and other cliff areas. There are no guardrails along many sections.
Rattlesnakes are present in eastern Washington and may be encountered on rocky trails and in shrubby areas, particularly in warmer months. Watch where you step and place your hands, and give any snake you encounter space to move away.
Water safety applies on the lakes: wear a life jacket when boating or kayaking. Lake water temperatures can be cold even in summer, especially deeper lakes fed by springs.
