Si Nakhon Kheun Khan Park

This is a vast botanical garden with a large lake and birdwatching tower in Bangkok's Phrapradaeng Peninsula. The wilderness is fantastic for hiking, birdwatching and cycling – bicycles can be hired locally for 100B. To get here, take the BTS to Bang Na, then hail a taxi to the pier at Wat Bang Na Nork. From there, take the river-crossing ferry (4B) followed by a short motorcycle taxi (30B) ride.
