Leave No Trace

All of the hot springs in this article are naturally occurring, which means they usually lie within public land. It is important for all visitors to following the Leave No Trace principles, such as:

  • Plan ahead and prepare—know the access rights & restrictions of where you’re going.
  • Dispose of waste properly—pack it in, pack it out. Leave nothing behind.
  • Leave what you find—leave natural objects in place, avoid building structures or digging.
  • Respect wildlife—do not feed or disturb wildlife in their natural habitat.

Cell-Phone Service Warnings

A lot of these hot spring destinations are remote and require a bit of hike to get to them. This also means that cell-phone service can be spotty.

Be prepared and download offline maps, and contact your friends before you lose signal.

Temperature Warnings

It is important to remember that the temperatures of these hot springs can get very hot. Depending on the exact location, and depth of the pools, many hot springs can reach temperatures of up to 104-130 degrees.

Be prepared for varying temperatures, and feel the water before dipping in.

Clothing is Optional

As most of these hot springs are located on public land—and far away from the actual “public”—it is common for visitors to treat the springs as clothing optional, meaning you are very likely to see some folks in their birthday suits.

What to Pack

Before heading to the hot spring, it is suggested you make sure you pack the following items:

  • Swimwear and towel
  • Water shoes—a definite must.
  • Water bottle—to stay hydrated during your sweat-sesh.
  • Dry Bag—for phones, cameras, music, etc.
  • Garbage bag—for ALL of your waste.

High-Traffic Areas

As of recent years, hot springs have become a very popular spot with both locals and tourists.

If you’d like to avoid busy times, it is suggested you go in early morning or later in the evening—which can both be prime times for sunrises and sunsets.

Party Goers

As with all natural hidden gems, once the public finds out about them a new crowd emerges. Unfortunately, hot springs are not just enjoyed by the quiet crowd and can become quite busy on weekends and hot summer nights.

Please enjoy responsibly.

Do Not Drink the Water

It is advised that visitors do not drink the water from the hot springs. Although they are naturally occurring, some of the hot springs contain particles that can lead to a serious disease called primary amoebic meningoencephalitis. 

Not to mention there are numerous bodies bathing in these waters daily.
