Khao Chamao-Khao Wong National Park in Talang District is comprised of two mountains (khao) which loom above the farming lowlands of the Eastern Seaboard. The evergreen forests are home to many mammals, (tigers, elephants, bears), and has a few developed trails. Park highlights include the Khao Chamao Waterfall and the 80 plus Khao Wong caves, including Tham Phet (diamond cave) and Tham Lakhon (theater cave).
During mid-May to the end of June, excellent quality and reasonably priced rambutans, durians, and mangosteens are widely abundant. Several fruit orchards provide a tour of their plantations and a chance to taste the delicious tropical fruits.
The busy and prosperous fishing community of Ban Phe is the main ferry embarkation point for Koh Samet and neighboring islands. It is also a popular market place for dried and fresh seafood products. A 20-km coastal road winds along from here to Laem Mae Phim , with a good stretch of crystal white sandy beach. Local tourists frequent the roadside vendors selling fruits, fried squid, and other local delicacies.
Five km past Ban Phe is the Suan Son (Pine Park), a favorite picnic area by the beach shaded by pine trees. Aside from eating seafood and other local delicacies while lounging on deck chairs, there are a couple of sports activities to enjoy.
The Sunthon Phu Memorial Park is a quiet, well-manicured garden in Kram village, the birthplace of Thailand's most famous poet's father.

Statues of the poem's characters and famous scenes are scattered around the park.
Within the town, the King Taksin Shrine commemorates King Taksin's brief stay in Rayong following the fall of Ayutthaya in 1767.

He is remembered as the monarch who rallied the Thais and successfully expelled Burmese invaders before establishing a new capital in Thonburi, on the western bank opposite Bangkok. The shrine is highly revered by Thais of Chinese ancestry and attracts large crowds during Chinese New Year.
