The Eco-Trails Festival in Casimiro de Abreu offers an invigorating outdoor experience set against the rugged Atlantic Forest of Rio de Janeiro. This annual gathering invites hikers and nature lovers to traverse varied terrain ranging from shaded forest tracks to open ridges where the wind challenges your footing and the native birds keep a watchful eye. Spanning approximately 15 kilometers, the main trail features an elevation gain close to 700 meters, demanding steady pacing and stamina without overwhelming even those newer to trail hiking.

The paths cut through thick canopies that seem to move themselves — branches swaying as if whispering secrets — while rivers alongside dare you to draw closer, their waters pulling forward with quiet strength. Sections of packed earth and exposed roots combine to keep your awareness sharp; waterproof shoes with solid tread are a must here. Expect the trail to unfold with frequent shifts: a steady climb is often followed by gentle descents overlooking spectacular views of the coastline and neighboring peaks.

Timing is key. The festival typically occurs during the dry season when humidity drops and the skies hold steady. Early morning departures will reward adventurers with cooler air and softer light spilling through the verdant foliage. Hydration is crucial — the forest’s humidity can trick you into underestimating fluid loss, so carry at least two liters of water. Lightweight, breathable layers that can be swiftly removed or added will serve well against shifting temperatures along the ascent.

Besides the physical challenge, the festival emphasizes respect for the natural environment. Trails are maintained to minimize impact, and participants are encouraged to engage with the local community and wildlife thoughtfully. Look carefully to spot birds like the uncommon Rufous-capped Motmot or the busy Southern Onça. Historical markers along the way highlight Casimiro de Abreu’s rich cultural tapestry, connecting hikers to its past while reminding that this land remains fiercely itself, requiring both admiration and caution.

Whether you’re striving to reach the summit’s panoramic lookout or moving steadily with a group of like-minded explorers, the Eco-Trails Festival balances the thrill of discovery with the responsibility of outdoor stewardship. It’s a call to challenge your limits practically — plan ahead, respect the trail, keep your gear tight, and don’t rush past the moments when the forest stops and gives you its full attention.
