Black Canyon Hot Springs (Colorado River)

Nevada-side river-edge hot pools in Black Canyon of the Colorado below Hoover Dam (Lake Mead NRA, Clark County NV — NOT California): primitive seeps/pools ~95-110F near Weeping Springs Cove across from the Arizona Hot Springs canyon, reached mainly by kayak from Willow Beach AZ or the permitted Hoover Dam launch; land trails (Arizona HS, Goldstrike) are closed every May 15-Sep 30 for lethal heat but the springs stay reachable by water.

Before you go — visit checklist

• ✓Status: Open — last verified below — confirm via NPS Lake Mead — 'Hike the Arizona Hot Springs Trail' (HEAT CLOSURE 5/8/26 notice; May 15-Sep 30 seasonal trail closure; springs open by water; no altering flow; 111-120F source; pit toilets).
• ✓Cost: Fees reported — confirm current rates before visiting.
• ✓Getting there: No verified hike distance on record — confirm the route and road conditions.
• ✓Water: No soak temperature on record — always test the water before entering.
• ✓Rules: Clothing policy unknown — verify locally; pets reported not allowed — confirm current rules.
• ✓Conditions: check weather, fire closures, and land-manager alerts the week you go — mountain access changes seasonally.
• ✓Reservations/permits: No permit to soak or to paddle from Willow Beach. Hoover Dam launch: NPS paddlecraft permit ~$32/person (<=15 yrs or ATB pass $16) through authorized outfitters only — date/time specific, names must match photo ID, sells out months ahead. $25/vehicle park entrance (card only).
• ✓Best time to go: October-May only (trails reopen Oct 1). Winter weekdays are quietest on the water; weekends Oct-Apr see steady kayak traffic and the Arizona Hot Springs canyon fills up by mid-morning. Avoid entirely May-Sep.
• ✓Clothing reality: No official NPS clothing rule; clothing-optional is customary at the canyon hot pools (Arizona Hot Springs especially). On the river itself normal swim/boat attire is the norm.
• ✓Kids: Allowed.
• ✓Cell service: none — download maps and tell someone your plan.
• ✓Accessibility: Very poor — water entry, gravel washes, ladders/rope descents, and steep slot canyons; nothing ADA-friendly beyond the Willow Beach marina area.
• ⚠️DATA ISSUE: 'ca-' prefix is wrong — these springs are in NEVADA (Clark County) on the west side of Black Canyon; the famous named spring across the river (Arizona Hot Springs/Ringbolt) is on the Arizona side. 'Black Canyon Hot Springs' is a generic label — named springs nearby are Goldstrike/Nevada Hot Springs and Boy Scout Canyon (NV side) and Arizona/Ringbolt (AZ side); the record's coords sit ~1 mi south of Arizona Hot Springs near Weeping Springs Cove
• ⚠️ANNUAL HEAT CLOSURE May 15 - Sep 30: NPS closes the strenuous land trails (Arizona Hot Springs trail, Goldstrike) every summer, plus temporary closures whenever >=95F is forecast at Willow Beach — canyon temps hit 120F+ and hikers die here. Springs remain legally open by water but summer paddling is dangerous heat exposure
• ⚠️HOOVER DAM LAUNCH = federal security zone: private vehicles cannot drive in; a per-person NPS launch permit (~$32, $16 for <=15 or America the Beautiful passholders) must be bought through authorized outfitters, is date-specific, non-refundable, and can sell out up to 6 months ahead
• ⚠️FREE ALTERNATIVE: launch/takeout at Willow Beach AZ (river mile 52.5) — public ramp, marina, kayak rentals, campground, store/restaurant; Emerald Cave ~2 mi upriver, hot-spring coves further up; no permit needed to launch at Willow Beach
• ⚠️Lake Mead NRA entrance fee $25/vehicle — NO CASH accepted
• ⚠️Colorado River here is ~52-55F year-round — the contrast between 110F pools and the cold river is real; PFD required on the water; capsize/hypothermia is a genuine risk for paddlers
• ⚠️Naegleria fowleri (brain-eating amoeba) is documented in Lake Mead-area warm water — a Clark County boy died in Oct 2022 after exposure on the Arizona side (Kingman Wash area), the park's first confirmed PAM fatality; never put your head under warm spring water or get water up your nose
• ⚠️NPS rules at the springs: altering flow is prohibited — no sandbags/pool-building; pit toilets 200 yd downstream of Arizona Hot Springs; pack out trash and human waste
• ⚠️Arizona Hot Springs canyon access involves a 20-ft ladder and steep scrambling; Goldstrike requires eight fixed-rope descents (~20 ft each) and Class 3 scrambling — not beginner terrain
• ⛔Hazard: Extreme heat — annual trail closure May 15-Sep 30; 120F+ canyon temps have killed hikers
• ⛔Hazard: Naegleria fowleri documented — 2022 fatality; keep head out of warm pools
• ⛔Hazard: 52-55F river water — capsize = hypothermia; PFD required
• ⛔Hazard: Flash floods in slot canyons
• ⛔Hazard: 20-ft ladder (Arizona HS) and fixed rope descents (Goldstrike) — fall risk
• ⛔Hazard: Hoover Dam security zone — strict access control at the upriver launch
• ⛔Hazard: No cell service in the canyon; self-rescue

Fact Sheet & Geothermal Specifications

Detailed Description

Natural hot-spring pools on the Colorado River in Black Canyon below Hoover Dam (Lake Mead NRA) — the Nevada-side canyon soak cluster near Arizona Hot Springs across the river, reached by kayak from Willow Beach or the Goldstrike Canyon scramble. Water ~95-110°F in river-edge pools.

Nevada Geothermal Context

Nevada has more hot springs per square mile than any other state — Basin and Range faulting brings deep thermal water to the surface across nearly every valley. Most sites are primitive seeps and tubs on public BLM land reached by long, unmaintained dirt roads. Carry extra water, and watch for flash floods in desert washes during storms.

What a primitive site means here

Primitive springs have no facilities: no changing rooms, no trash service, often no maintained road to the pool. Expect natural rock or gravel bottoms, water temperature that varies by spot and season, and other visitors who may treat the site informally. Pack out everything you bring, test the water before entering, and leave the pool cleaner than you found it.

Directions & Trailhead Access

By water only: kayak/canoe down Black Canyon from the Hoover Dam launch (permit required) or up from Willow Beach — Nevada side near Weeping Springs Cove.

Desert thermal zones experience high summer ambient heat. The cooler months from late autumn to early spring offer the most refreshing ambient conditions for open-air soaking.
