I spent two weeks in Myanmar in July. I only managed to visit Yangon, Bagan and Inle Lake
I really enjoyed exploring Yangon on foot and also taking the ferry across to Dalah (Some guide books indicate you need to get a permit, but this is no longer the case, just rock up at the ferry terminal). The Shwedagon Pagoda was lovely to visit, and in downtown Yangon I think it was Bank Street (it's easy to get to from Maha Bandoola Garden Street and is on the way to the ferry terminal) that I thought was really cool - loads of cute little food stalls and tea stalls.
I took a train to Bagan (In hindsight I wouldn't recommend the train, as its a very long bumpy ride with no access to food).
Bagan was AMAZING!!! It's worth spending several days exploring the area at your leisure - though I recommend early morning and late afternoon, and taking a siesta in the middle of the day. A sunset rivier cruise up the Ayerwaddy is worthwhile too.
It's important to take it slow here!
Inle Lake (nyuangshwe) was also fantastic, super chilled, gorgeous scenery and amazing people. A full day trip on the lake is a must. A cycle out to Red Mountain Vineyard is also worthwhile, and if you are up for a bigger ride then I recommend riding out to Kaung Daing.
Myanmar was fabulous. Just make sure to take your time and soak up the culture. about 6 years ago
