Best Swimming Holes near Spokane, WA

Eastern Washington runs on a different clock than the rainy side of the Cascades. While Seattle swimmers wait out June clouds, Spokane bakes under a continental sun that heats up fast — and so do the rivers, lakes, and creeks fanning out from the city. The Inland Empire sits at a geographic crossroads where the dry ponderosa-pine scablands of the Columbia Plateau bump up against the granite peaks of the Selkirk and Cabinet mountains, giving swimmers a surprisingly diverse menu: warm shallow lakes perfect for families, cold mountain-fed creeks that stay refreshing even in August, and scenic river corridors you can float or wade through on a weekday without fighting a crowd.

Unlike western Washington, where the snowmelt pulse keeps rivers dangerous well into July, Spokane-area rivers and lakes warm meaningfully by late June, making the swimming season here one of the longest in the state. The trade-off is that summer storms can bring brief flash-flood pulses and recreational smoke events from wildfire season. Still, the combination of hot, dry days and cold, clear water means that from late June through Labor Day, Spokane is one of the best base camps in the Pacific Northwest for freshwater swimming adventures.

The city itself sits along the Spokane River, and while the urban stretch is not recommended for swimming, you only have to drive a short distance in almost any direction to find conditions that are genuinely excellent. Whether you want a calm sandy beach for a picnic swim, a cold creek to wade through on a trail run, or a remote granite-rimmed lake that requires a bit of a hike, it is all within a 90-minute radius.

TL;DR:

Swimming season runs late June through early September — Eastern WA warms faster than the west side.
The Little Spokane River offers a calm, shaded, beginner-friendly float north of the city.
Medical Lake and Liberty Lake are warm, family-accessible choices with amenities.
Granite Lake in the Selkirks rewards a short hike with clear mountain water and stunning scenery.
Always check for blue-green algae (cyanobacteria) advisories on lakes before swimming.

Top 5 Swimming Holes Near Spokane

[[Listing: LITTLE SPOKANE RIVER]] – The crown jewel of Spokane-area swimming, the Little Spokane River winds through a quiet natural area about 15 minutes north of downtown. The water is clear, the current is gentle enough for swimmers of most skill levels, and tall cottonwoods and ponderosa pines shade the banks for most of the afternoon. A popular launch at St. George's Road lets you float downstream through undeveloped land managed as part of the Little Spokane River Natural Area. Depth varies from knee-high riffles to chest-deep pools, making it ideal for families. Bring an inner tube and plan for a few hours — this is the locals' go-to for a reason.
[[Listing: STEVENS CREEK]] – About 45 minutes south of Spokane near the town of Cheney, Stevens Creek feeds into a mosaic of wetlands and public lands in the channeled scablands. While it does not have formal swim beaches, a handful of deep pools along the creek corridor have become beloved among Spokane-area hikers and trail runners looking to cool off after a workout. The water stays noticeably cooler than the lake alternatives well into August thanks to groundwater inputs, and the basalt-rimmed banks give the area a dramatic character entirely distinct from the pine-forest spots to the north. This is a quieter, more exploratory swim — come prepared to do a bit of searching for the best pools.
[[Listing: MEDICAL LAKE]] – About 20 minutes southwest of Spokane, Medical Lake is a small mineral lake with a quirky history — its alkaline waters were once marketed as a health cure in the late 1800s, and the town that grew around it still bears the name. Today it is a relaxed summer recreation spot with public beach access, calm water, and plenty of room to spread out. The lake is relatively shallow and warms up quickly in the summer sun, making it one of the earliest spots in the region to reach a comfortable swimming temperature. A small park with picnic tables, restrooms, and a grassy lawn makes it one of the most family-accessible options near Spokane. Arrive early on weekends in July and August.
[[Listing: LIBERTY LAKE]] – Situated about 25 minutes east of Spokane just off I-90, Liberty Lake is Eastern Washington's most polished lake-swimming experience. The Liberty Lake Regional Park offers a groomed sandy beach, a swim area with buoys, seasonal lifeguards, picnic shelters, and a paved trail system that loops the entire lake. The water is warm by mid-July and the park draws families from across the Spokane metro area. For a quieter experience, the eastern shoreline accessible via the Edith Hanson Discovery Trail offers more secluded spots to wade in away from the main beach. The park charges a small day-use fee on summer weekends — arrive before 10 a.m. to avoid the parking crunch.
[[Listing: GRANITE LAKE]] – For those willing to earn their swim, Granite Lake sits in the Selkirk Mountains about 80 miles north of Spokane in the Kaniksu National Forest. The hike in is roughly 4 miles round trip with moderate elevation gain, passing through a forest of old-growth western red cedar and hemlock before emerging at a stunning lake cupped in a granite cirque. The water is cold — genuinely cold, even in August — but remarkably clear, and the setting is among the most beautiful within reach of Spokane. Pack a wetsuit or be prepared for a brief but bracing dip. A Northwest Forest Pass is required at the trailhead. Plan this as an all-day outing and you will not regret it.

When to Go

The Spokane swimming season opens meaningfully in late June, when lakes like Medical Lake and Liberty Lake begin hitting comfortable temperatures in the upper 60s°F. Rivers and creeks reach their best conditions in July and August, after snowmelt flows have subsided and water levels stabilize. August is the prime month overall — days are hot, water temps peak, and flows are manageable. By mid-September, nights turn cool and water temps drop quickly. Mountain lakes like Granite Lake run cold all summer but are most tolerable in late July and August. Weekday visits dramatically reduce crowds at popular spots like Liberty Lake.

Safety & Access Notes

Blue-Green Algae: Eastern Washington lakes are prone to harmful algal blooms in warm, still conditions. Check the Washington Department of Ecology's online advisory map before visiting any lake. Never swim if the water looks green, foamy, or smells musty.
Cold Shock: Even warm-looking rivers can carry cold groundwater inputs. Enter slowly and avoid hyperventilating after a sudden plunge.
Currents: The Spokane River itself has dangerous hydraulics near several dam structures — stick to the tributaries and lakes listed here.
Sun Exposure: Eastern Washington sun is intense. Sunscreen, hats, and shade breaks are essential, especially for kids.
Northwest Forest Pass: Required at Granite Lake trailhead and some other Kaniksu National Forest access points.

Is the water safe to swim in near Spokane?
Generally yes, but always check for blue-green algae advisories on lakes before entering. Rivers and creeks in the area are typically clean, especially in the upper watersheds above development. Avoid swimming in the main Spokane River corridor through downtown due to pollutant and hydraulic hazards.

Do I need a permit for swimming holes near Spokane?
Liberty Lake Regional Park charges a day-use fee on summer weekends. The Granite Lake trailhead requires a Northwest Forest Pass or America the Beautiful Pass. Medical Lake's public beach is generally free. The Little Spokane River Natural Area is free to access.

What should I bring to a Pacific Northwest swimming hole near Spokane?
Sun protection is critical in Eastern Washington — sunscreen, a wide-brim hat, and UV-protective clothing. Bring water shoes for rocky creek beds, plenty of drinking water (no potable water at most sites), snacks, and a towel. For Granite Lake, pack layers since temperatures drop quickly at elevation. A dry bag for valuables is always a smart addition.

Responsible Recreation

Eastern Washington's natural areas face increasing pressure as Spokane grows. At all swimming spots, pack out everything you pack in — including food scraps, fishing line, and single-use plastics. Do not build rock dams or cairns in creek beds, as they disrupt fish passage and aquatic habitat. At lakeside parks, stay within designated swim areas. At undeveloped sites like Little Spokane River, use established entry and exit points to minimize bank erosion. Respect fire restrictions during the dry season — campfires and charcoal grills are often prohibited in late summer. Leave these places better than you found them.
