By Air: The closest airport to Chompoo Wildlife Sanctuary is U-Tapao Rayong Pattaya International Airport. After landing, you can take a taxi or rent a car to reach the sanctuary, which is approximately 56 km away.
By Bus: Regular buses run from Bangkok to Pattaya. From the Pattaya bus terminal, you can hire a local taxi or a songthaew (a shared taxi-like service) to take you to Chompoo Wildlife Sanctuary.
By Car: If you're driving from Bangkok, take Highway No.7 (Bangkok-Chonburi-Pattaya Motorway) and exit at Pattaya. Follow local signs towards Khao Chichan (where the Big Buddha Image is engraved on the mountain), from there you can find directions to the Chompoo Wildlife Sanctuary.
By Train: A less common approach would be to take the train from Hua Lamphong Railway Station in Bangkok to Pattaya. Trains are infrequent and slower but offer a scenic route. Upon reaching Pattaya, you'll need additional transport like a taxi to get to the sanctuary.
Remember to check local travel advisories and transport schedules ahead of your journey as times and services may change.
