What is the best route from Monteverde to Tamarindo. I shall be in Costa Rica March 2018 and have rented a 4WD vehicle.
The best way is to take Route 606 to Route 1 to Route 21. On 21 you will pass the LIR airport and follow signs for Tamarindo. Take Route 155 from there and continue to follow the signs. All is nice paved roads except Route 606. Check out our Road Conditions of Specific Routes and our Driving to Monteverde posts for more specific conditions.
