I visited MOTOR Park in ECR, they have ATVs and Dirt Bikes, for two laps in ATVs they charged 250Rs, its located near the Kovalam Bridge. Attaching pictures.
GTO, the ride was fun and tricky as they have 2 or 3 sand mound to climb, those were brand new ATVs, the owner told me they costed around 3 Lakhs each, but i think they were speed limited.
