What to Bring to a Hot Spring: The Complete Packing List
Last updated October 7, 2026 · 3 min read
What you pack for a hot spring depends on where you are going. A resort day pass needs little more than a swimsuit. A primitive spring two miles up a forest trail needs the same kit as any short hike, plus a few extras for the water. Use the lists below as a starting point.
The essentials for any hot spring
- Swimsuit, even if the spring is clothing optional. You can decide when you get there.
- Towel. A quick-dry microfiber towel is lighter and packs small.
- Water to drink. At least a liter per person for a short visit. Hot water dehydrates you faster than you expect.
- Sandals or water shoes with grip. Pool edges, travertine and mossy rocks are slippery.
- Warm layers for afterward: a fleece or puffy jacket, a hat and dry socks. Your body cools quickly once you are out.
- A bag for wet clothes and another for any trash.
Extras for natural and primitive springs
- A thermometer. A cheap floating pool thermometer or a cooking thermometer tells you whether a pool is 102°F or 115°F before you put a foot in.
- Headlamp, even for a day trip. Soaks run long, and trails are hard to follow at dusk.
- Navigation. Download offline maps before you lose signal. Many springs are on unmarked side trails.
- Snacks and more water than you think you need.
- First aid basics, including blister care and bandages for small cuts from rocks.
- Nose clip if you want extra protection from the rare amoeba Naegleria fowleri in warm fresh water. See our safety guide.
- Trowel and toilet paper bag, so you can follow Leave No Trace rules where there are no toilets.
- Recreation pass if the land manager requires one for parking, such as a Northwest Forest Pass in parts of Oregon and Washington.
Extras for winter soaks
- Insulated boots and a dry pair of socks for the walk out.
- A warm hat to wear in the water. You lose a lot of heat from your head in cold air.
- A thermos of tea or warm water.
- Traction devices for icy trails and parking lots.
- Four-wheel drive or chains, and a backup plan if the road is closed. Read our winter hot springs guide for more.
Extras for resorts and developed pools
- Reservation confirmation. Many popular pools now sell timed entry and sell out on weekends.
- Flip-flops for locker rooms.
- A lock if lockers do not include one.
- Cash or card for entry, rentals and food.
What to leave at home
- Glass bottles. Broken glass in a pool is dangerous and nearly impossible to find.
- Soap, shampoo and sunscreen for natural pools. They leave a film on the water and harm life downstream. Shower before you go.
- Loud speakers. Most people come for quiet.
- Silver jewelry. Sulfur can tarnish it.
- Your dog, unless you have confirmed dogs are allowed. Even then, keep it out of the pools.
Before you leave home
- Check the spring’s page in our directory for the recorded temperature, type and nearest town.
- Confirm hours, fees and road conditions with the operator or land manager.
- Tell someone where you are going if the spring is remote.
- Check the weather. Rain can make dirt roads impassable, and spring snowmelt floods riverside pools.

Frequently asked questions
What should I wear to a hot spring?
A swimsuit for most developed pools, plus sandals or water shoes with grip. At clothing-optional springs, swimwear is still fine. Bring warm, dry layers for after your soak, because you cool down fast.
Should I bring a towel to a hot spring?
Yes. Some resorts rent towels, but most natural and public springs do not provide them. A quick-dry towel packs small for hikes.
Can I wear jewelry in a hot spring?
Take it off. Minerals and sulfur in the water can tarnish silver and some other metals, and rings are easy to lose in murky pools.
