The most useful thing to know before choosing a sightseeing stop is that “near Vijayawada Airport” can mean two very different things: somewhere around Gannavaram, or a drive into Vijayawada to see the landmarks most visitors have in mind.
If you have a few spare hours before check-in, a trip to the city can become stressful quickly. If you have most of a day, though, the temples, riverfront and rock-cut caves make a rewarding visit. The trick is to choose one part of the region and give it enough time.
Start with the clock, not the attraction list
The places I’d shortlist

Bhavani Island
This is the slower-paced option: river scenery and outdoor time rather than another stop in the city traffic. Getting there depends on the current boat service and boarding point, so check those before committing to a schedule.
It makes more sense when you have a flexible half-day than when you’re watching the clock for a flight.

Undavalli Caves
Choose the caves if the architecture itself is the reason for your visit. The rock-cut complex is more rewarding when you can walk around without rushing back to a vehicle straight away.
Wear shoes suitable for steps and uneven ground, and verify current access details before setting out.

Kondapalli Fort
This is a separate excursion, not a quick airport stop. Go for the fort and the surrounding hill setting, and allow the visit to be the main event rather than squeezing it between city landmarks.
And what about Kanaka Durga Temple and Prakasam Barrage?
They are two of Vijayawada’s signature landmarks and can work together in a city-focused outing if time and traffic allow. The temple sits on Indrakeeladri Hill by the Krishna River; the barrage is both a river crossing and a familiar city sight. During major religious festivals, crowd levels around the temple can change the timing of the entire visit.
Check current darshan arrangements with the temple’s official website, and use the district tourism listings for a starting point on local attractions.
One practical detail: distance estimates differ
The Airports Authority of India places Vijayawada Airport at Gannavaram and gives a distance of about 25 km from Vijayawada in its airport description. Its fact sheet also references an 18 km city distance, illustrating why a single number can be misleading without a precise destination. For planning, enter your actual hotel or attraction in a map app and check the road route on the day.
