Tip
Book a guide or go through the Montaña Sagrada reserve near Sucre — the national park itself doesn't take walk-in visitors — and pack a rain jacket even in the dry season.
Be careful
Trails are steep and muddy and fog closes in fast; stay with your guide and on the trail.
Getting there
Guided visits only (the park lists no regular tourist entry); tours start from the Sucre / San José de la Montaña side.
