The municipality is readily accessible through navigation along the Catubig river with the use of pump boats and bancas. The pump boats ply from Las Navas to Catubig daily at PhP 40.00 (US$0.80) per person. These small boats dock at small docking facilities called “Look” in both Catubig and Las Navas. It only takes 30 minutes to get to Las Navas from Catubig, and boats traverse the river daily, leaving Las Navas at 5:00 a.m. and arrives at around 5:30 a.m. in Catubig (and vice versa).
Motorboats and bancas are used in going to the different barangays, although hiking is still practiced by many barangay folks in going to and from the Poblacion.
Las Navas today is now connected to the national road system The road and Las Navas bridge was formally inaugurated by President Gloria Mcapagal Arrroyo last June 16, 2009.
