Challenge yourself into trying out some extreme sports and adventurous activities: from sky-diving to midnight safaris. You can't afford to miss some adventure activities that attract millions of tourists every year: hiking, heritage trails, and island-hopping.

There are plenty of reasons to go outside in this city. Get off the couch, put the Netflix binge sesh on hold and strap on a good pair of shoes and embark on one of these outdoor adventures:

1. Sungei Buloh Wetland Reserve

"Wow! It's so green!" emerges as the top observation that visitors make about Sungei Buloh. It is the island nation's first ASEAN Heritage Park and encompasses 202 hectares where you can have free guided walks. It is a haven for bird watchers year-round.

Some of the must-dos would be hiking along the nature trails. There are also numerous guided tours operated by the NParks Board. Its unspoilt mangrove estuary also promises to catch glimpses of native inhabitants such as mudskippers, crabs, shellfish, water snakes, birds, spiders, monitor lizards and otters.

2. Forest Adventure

For anyone who has a fear of heights, it is encouraged for you to try out Forest Adventure to overcome your fears. Tackle an obstacle course at Forest Adventure for a time of thrill and fun with the wide variety of height elements. Apparently there is a special rate just for adults on every Tuesday and for tertiary students during the weekdays. 

Forest Adventure's Kids Course has 22 obstacle crossings with 2 zip lines and is designed for those between the ages of 5 and 10.

Entrance is at $36/$39 for children depending on which course and $25 for accompanying adult, while $50 for adults. You can find Forest Adventure at the Bedok Reservoir Road.

3. Chestnut Nature Park

You can show off your bike tricks on Singapore's first pump track and four circuit zones that range from easy to intermediate.

Chestnut Nature Park is divided into South and North parts. The park encompasses an area of 81 hectares where visitors can peacefully wander in its greenery where you can do recreational activities such as bird watching, hiking and mountain biking.

You can spot threatened bird species such as the Straw-headed Bulbul, Brown-chested Jungle Flycatcher, and other species such as the Banded Woodpecker, Orange-bellied Flowerpecker and Little Spiderhunter here.

4. The Water Sports Centre

You and your date can kayak around The Water Sports Centre. Kayaking in the calm waters is also one of the best family-friendly water sports in Singapore. The activity is great for both - solo as well as groups, and you can compete with your family and friends as well at the 500-metre Regatta course mapped out on the Kallang Basin.

The Water Sports Centre offers a variety of canoes, kayaks and pedal boats for rent. The knowing instructors will be able to help you and the facilities are nice and clean.
