On the way to Hue there is the famous Hai Van Pass, which has truly incredible views down the coast and through the mountains. Driving through it and stopping at the top was brilliant.
Accomodation
Hue Happy Homestay: well situated near the tourist area.
Activities
There is an abandoned water park near Hue that you can enter for a few thousand VND and explore at your leisure, and also a few different temples around the city.
Food
The best Banh Mi I had here was on the street opposite a Mr Bean Bar, which was quite a funny little place.
@rkmkiosk It was pretty damn warm. It's supposedly cooler the further north you go but I experienced very similar temperatures throughout the entire trip with just a couple of outliers. It was mid to high 30s (celsius) pretty consistently. It's very very high humidity as well, so google was telling me it 'felt like' closer to 50 some days in Hanoi. That was particularly bad though, Id adjusted to 40ish after a couple of weeks.
The only exceptions were Dalat (a mountain city, reached as low as 18 at night, and Ha Giang near the Chinese border would rain a lot so it was closer to 20s than 30s. Still overall very warm though, I wore the same clothes just with a waterproof on, and the rain wasnt too bad because I was so hot!
How hot is it in june? Btw amazing itinerary
