Tiên Sa Waterfall makes for a nice destination if you plan to go on a moderately challenging hike into the area. The nature envelops you all around, though be ready to climb and descend a lot of steps on your way towards it.
It's a nice trail to take if you are in the nearby Cat Cat village and definitely worth a visit.
