There are many eco-tours which typically go to the Temburong district by boat then to a native "longhouse". It is then followed by a powered boat (by the natives) up the river to the Belalong National Park, a reserve in the Borneo rainforest. There is a canopy walk and research centre at the park headquarters.
Jerudong Park was once a decent theme park with a multitude of rides. Sadly, a downward cycle of neglect, declining admission and unaffordable maintenance costs led to the closure and sale of most of the big-ticket rides, including the three rollercoasters. This has given the park a sad "circus left town last week" air about it. Most people who visit only go at night to avoid the heat during the day. Outside the park, but very close, is a small complex of restaurants which is open at night, though only a few of the stalls are still operational. The local papers have reported plans to renovate the park with a new selection of attractions, but as of March 07 it remains to be seen what these attractions will be and when they will be operational.
As of March 2010, there's a talk going around that Jerudong is getting better and work to improve the place is taking place.
