Soak in the hot springs

Arenal sits on a network of natural hot springs heated by the volcano, and soaking in them is the quintessential La Fortuna experience. At the top end, lavish resorts like Tabacón offer landscaped thermal rivers and pools with a day pass, a genuine treat worth the splurge for many. But here's the budget secret: locals soak for free in the Rio Chollín, a natural hot river near the Tabacón resort where you can ease into volcano-warmed water at no cost. Both are special in their own way. We'll explain the resort options, the free river spot, and how to enjoy each safely.
