Naejangsan National Park is known throughout Korea as one of the best places to see the Autumn foliage. As with all National Parks, it's huge! Even after living in Korea for over 3 years I only just found out that there are in fact two separate temples which are on different sides of the park, each falling in a different province. Naejangsan Temple is in Jeollobokdo (click here for a full post on how to get there) and then Baekyangsa Temple (featured in this post) is actually in Jeollonamdo and closer to Gwangju.
Both temples are beautiful and offer spectacular scenery, but Baekyangsa was my favourite. They are pretty far from each other and unless you have your own car, it would be very hard to get to both in one day. Naejangsan Temple is quite a far walk from the parking lot where the bus from Jeongeup drops you off, but there are lots of food stalls and beautiful leaves to keep you occupied as you make your way up to the temple. The temple at Baekyangsa was a much shorter walk from the parking lot, and had a lot more diverse scenery, and was my favourite place to photograph.
If driving, I have posted the address below. We started at the Naejangsan temple parking lots and then drove the 35km to Baekyangsa temple. The roads weren't very well marked and the sign posts were very erratic. It ended up taking over 1.5 hours to make the 35km journey. You might have better luck by bus going from Gwangju, however as I haven't made the journey by bus I can't offer too much info on it. When in doubt, call the English Helpline (1330 from any cellphone) here in Korea, those guys and girls work magic and will help direct you where you need to go with bus times and other useful info.
There was ample free parking near the entrance to the National Park (W3 000 per person). From there the walk to the temple was beautiful, with lots of views of the mountains and streams.

Just a note
Dogs are not permitted in the national Park (although we did see a few little fluffy heads poking our of handbags and backpacks). #ShadowtheJindo is too big to hide in a bag and so had to stay at home for this trip. National Parks don't allow dogs, but Provincial Parks like Seounusa and Gaemsa Temple near Gochang are pet friendly as long as your dog is lead.
