This pagoda at the north-west end of town has nice views of the sunset. You can watch from a viewing tower or at the side of the river next to the pagoda.

This lake in the lower part of the city and its wooden bridge are recommended in the evening.
Take a boat across the river to Hpa-Pu and learn something about the history and name of Hpa-an. If you feel energetic you can hike up the hill north of Hpa-Pu.
This used to be a great experience and impressive nature spectacle when an endless stream of 100,000s of bats came flying out of their cave at sunset (check the sunset time). However locals seem to dislike the colony and each evening departure sit banging drum & shacking noisy rattle which disturbs the bat departure causing bats to emerge and scatter rather than forming the dramatic ribbon formation (the "ribbon" formation eventually reforms some distance away). The bats start coming out of the cave almost exactly at sunset, and the whole spectacle now takes less than 1 hr (although the vast majority of bats fly out of the cave in the first 10 min). Bring patience and a torch (for the walk back). Go a bit earlier and climb up the nearby hill in front of the cave with a stupa on top to have a stunning view of the river and countryside. The best place to see the bats is near the stupa at the base of the stairs. About 5,000 kyat for a taxi to get there and back from Hpa-an. It can also be booked as a tour with most of the guest houses.
A monastery in the middle of an artificial lake filled with uncountable amounts of small (jumping around) and big fish (sticking out their mouths). It contains a pillar-like and interestingly stable or to say impossibly still standing rock with a pagoda mounted on top. Looks very nice for a couple of pictures. The rock can be climbed. Before the lake another golden temple with a nice looking Buddha statue can be visited.
Mount Zwe Kabin
From the top it offers a spectacular 360° views of the surrounding planes, especially when the air is still clear, i.e. in the morning and during wet season. It takes up to 4 hr to walk up the 723 m mountain and down again. Bring enough water for the climb and heat. There are at least two main tracks, one leading up north from "Lumbini Garden" and another one going down and east towards the main road that serves Kaw Ka Taung Cave, Ein Du village and Saddan Cave. However it will be hard to use both tracks if you come with rented motorbike. After an accident in February 2017 it is not possible to stay overnight at the top.
The entrance to this cave is 116 feet above sea level. Stemming back from the 17th century. With three Buddha images (standing and sitting), nearly 5 feet in height. It is located close to the village with the same name. Top of the hill exit has an amazing sunset view deck.
