Numerous mammals can be found in the national park and species such as the red-bellied filander, the red-necked wallaby and the wombat have become more common ever since the park was protected. While the Tasmanian devil and the spotted marten were more common in the past, it's now believed that they only live in a smaller population in parts of the park.

On the coasts you can observe the South African fur seal, leopard seal and elephant seal. The waters are also frequented by dolphins of various species, pilot whales, southern capers and humpback whales.

Due to the diverse habitats, numerous species of birds also find their habitat here. These include the little penguin, the endangered species Thinornis rubricollis (a plover) and the wedge-tailed eagle and the white-bellied sea eagle.

• -43.18728147.8444091 Remarkable Cave, 7182/446 Safety Cove Rd. This sea cavern (not cave, despite its name) may look like any other sea cavern, but when you look at it closely, you'll see the gap looks exactly like the shape of Tasmania but without its many peninsulas on all sides. Getting to the cavern's lookout is a 15-minute walk (return) from Maingon Bay Lookout but has many stairs that you will need to walk up on return. (updated Dec 2021)
• -43.195246147.853372 Maingon Blowhole, Mount Brown Track. While much less well-known than neighbouring Remarkable Cave, if you're into photography, this blowhole is well worth a visit. Visiting the blowhole requires a one-hour walk (return) from Maingon Bay Lookout, but note that sections of the trail are steep and slippery, especially after rainfall. (updated Dec 2021)

• -43.20837147.775764 Cape Raoul Lookout, Cape Raoul Track. A jaw-dropping lookout but is only accessible via a 14-km, 5-hour (return) track. The views from this lookout partially characterise the landscapes of this park. (updated Mar 2024)

There is a small section of Tasman National Park in Eaglehawk Neck, which include major sites such as Fossil Bay, Tasman Arch and the Devils Kitchen, connected to the township by a small road – this does not connect to any other locations in the park. As such, these sites are covered in Eaglehawk Neck § Tasman National Park. You will still require a Tasmanian national parks pass to visit these sites, but are covered there for practical purposes.
