Atimonan Baywalk

The remains of a Spanish-era coastal watchtower built in the 18th century to defend Atimonan against raids by Moro pirates and other foreign invaders such as the Dutch. The site was declared a national cultural treasure by the Philippine government in 2020.

It was first built in 1643, but was repeatedly destroyed by a fire and an earthquake. The present church was built between 1687 and 1700. The church's ceiling and interior dome have paintings of archangels, the Virgin Mary, and symbols of heavenly authority.

It is a protected landscape on the southern end of the mighty Sierra Madre range, which straddles the boundary with Pagbilao. It was founded in 1934 as a national park until it was elevated into a protected area in 2003. It covers of tropical rainforests, home to endemic species of birds, reptiles, mammals, and trees. Inside the park is Mount Pinagbanderahan, where a Philippine revolutionary flag was raised, and is reachable through an hour of hiking. There are also caves and waterfalls within the park, and some campsites.
