Why should you go there and how do you do it right?

If you lower your expectations a bit, you'll be rewarded. It's a free wooden boardwalk through the mangrove forest of Pak Nam Pran, which you can cross at a normal pace in 15 to 20 minutes. Some find that a bit unspectacular, and I can understand why. Down at the boardwalk, you only see water and trees, nothing particularly special. The trick is to take your time. Look at the roots near the water, and you'll spot black crabs climbing up them. Climb the tower to enjoy the view over the canopy—that's where the photos so many people post are taken. Send someone from your group up and stand on the path below to get the perfect shot.

At the far end is a beach that's almost always deserted, and a campsite right by the sea if you'd like to stay overnight. A shop sells food and drinks, the toilets are clean, and parts of the park are still under construction. Halfway along the trail, you can book a boat trip on the river – the best way to observe the local fishing life. Children, older hikers, and pets can easily navigate the level wooden boardwalk on weekends.
