Butterfly Valley is a climber’s paradise, boasting approximately 60 established routes (with more in development) and an array of challenging overhangs and steep climbs. The valley’s limestone cliffs are covered in tufas, creating a unique and captivating landscape for climbers of all skill levels to explore.

Reaching this remote destination can be an adventure in itself. The two main options are hiring a guide or navigating independently. Opting for a guide is ideal for those seeking insights and instruction on climbing techniques, while independent exploration suits those on a tighter budget with climbing experience.

The valley’s heart-shaped layout and abundance of butterflies make it a romantic and enchanting spot. Thousands of colorful butterflies flutter amongst the trees, creating a magical atmosphere. The contrast between the quiet, cool forest and the bustling activity of tourists and birds emphasizes the valley’s peacefulness.
