Safety on Highway 3 is generally good, but be cautious of overtaking slow farm vehicles and motorcycles. There are several well-marked emergency call boxes and hospitals in major towns.

For families, the Shark Fin Cave in Chumphon offers shallow pools and gentle trails, suitable for children. Alternatively, the Nong Nuch Garden in Pattaya, about 200 km north, is a family-friendly botanical garden.
