Why Choose Garapa for Boardwalks

Garapa boardwalk lumber makes real tropical hardwood boardwalks accessible for nature preserves, parks, and municipalities with tighter budgets. At the most affordable price point among exotic hardwoods, Garapa delivers genuine hardwood boardwalk benefits — splinter-free surface, zero chemical leaching, natural rot resistance — for projects that would otherwise default to pressure-treated pine.

The golden-yellow to blonde tones of Garapa boardwalk decking blend naturally with park and forest environments. Where darker woods can feel heavy in a natural setting, Garapa's light color complements the landscape — ideal for nature trail boardwalks, wetland crossings, and park paths where the wood should harmonize with the surroundings rather than dominate them.

At 1,630 Janka — nearly five times harder than pine — Garapa handles regular foot traffic for 30+ years. That's still 2-3 times longer than pressure-treated pine, eliminating at least one full replacement cycle. The wood is also the lightest tropical hardwood option, which can reduce substructure requirements and installation costs for elevated nature trail boardwalks. For parks departments stretching budgets while upgrading from PT to real hardwood, Garapa delivers the biggest bang for the buck.
