The best time to visit hot springs, state by state
Hot springs are a year-round destination with a secret: the best season is the one everyone else skips. Here's the calendar.
Winter: the glory season (December–February)
Steam rising off 104°F water while snow settles on your shoulders is the single best argument for cold-weather travel in the American West. Colorado's resorts run at full glory — Glenwood, Pagosa, Ouray, the San Luis Valley oases — and the contrast between freezing air and hot water is the entire point. Oregon's forest springs in rain and mist are peak Pacific Northwest. California's desert springs (Tecopa, Desert Hot Springs) hit their mild-weather sweet spot. Caveats: high-elevation wild springs may be snowed in, desert roads need winter driving prep, and holiday weekends at famous resorts sell out — book day-use ahead.
Spring: runoff and renewal (March–May)
Shoulder season with an asterisk. Rivers run high with snowmelt, which can flood or close riverside wild pools — check conditions before hiking to any river-adjacent spring. Forest roads start reopening in May. The developed resorts are quiet and lodging is cheap. Desert springs are still pleasant through April, then the heat arrives. This is the season for resort soaks, not wild expeditions.
Summer: dawn patrol (June–August)
Summer is the busiest and trickiest season. Famous resorts are packed on weekends — reservations essential. Desert springs become dawn-or-dusk-only destinations; midday soaking in 110°F air is miserable and dehydrating. Wild mountain springs are at their most accessible, but also their most crowded — go midweek, go early. Fire season (June–November in California and parts of Oregon) can close forest-access springs with little notice; check current orders before driving out.
Fall: the sweet spot (September–October)
Ask serious soakers for their favorite window and most will say early fall: crisp air, hot water, thin crowds, aspen gold in Colorado, harvest-season calm in California wine country, empty forest pools in Oregon. Rivers have dropped to safe levels, roads are still open, and the summer hordes are gone. If you can only take one soaking trip a year, take it in October.
Colorado by season
Winter is the marquee — book weekend day-use at Glenwood and Pagosa ahead. Late September brings aspen gold and elk bugling near the mountain resorts. Mud season (April–May) is the value play: quiet pools, cheap lodging, but high wild springs still snowbound. Summer weekends at famous pools need reservations; wild springs are weekday mornings' reward.
California by season
The state splits in two. Desert springs (Tecopa, Desert Hot Springs): October–April only. Sierra and mountain springs: best May–October, snowbound in deep winter. Coast and wine-country resorts: year-round, with spring and fall the sweet spots. Fire season is the wildcard for every forest-access wild spring — have a backup plan from June through November.
Oregon by season
The forest springs are a year-round destination, and rain is a feature — a Cascade soak in the rain is peak Oregon. Winter closes high-elevation access roads; Bagby needs reservations in every season. The high-desert springs (Alvord, Mickey, Hart Mountain) are stark and spectacular in winter but demand real winter-driving preparation on remote dirt roads.
The one-trip strategy
If you're planning a single trip: go in October, pick one state, and mix one developed resort with one wild spring. Book the resort's day-use or lodging ahead, hit the wild spring on a weekday morning, and pack for 40-degree temperature swings. That's the trip the photos don't quite capture — and the one you'll actually remember.
