History
Tenorio’s protected area was established as part of Costa Rica’s late-20th-century conservation push; volcanic activity and local farming shaped settlement patterns around Bijagua.
Conservation
Río Celeste’s color depends on delicate chemical and hydrological balance—avoid soaps in streams, stay on trails, and support local guides who practice low-impact tourism.

Wear grippy shoes
Trails are muddy and have steep stairs near the waterfall—trail-running shoes or light hiking boots help prevent slips.
Bring a rain shell
Rain can start suddenly even in the dry season; a lightweight waterproof layer will keep you comfortable and protect electronics.
Carry cash for lunch and tips
Small roadside sodas and local guides often prefer cash; park fees are usually covered but extra purchases may not be.

Sloths and birds are easier to spot by pausing quietly at shaded trail shoulders rather than rushing by.
Sturdy hiking shoes
Provide traction on muddy steps and uneven roots near the falls.
Light rain jacket
Quick showers are common; keeps you dry and warm on wet stretches.
