Nha Trang is a different city to many in Vietnam, it has already become commercialised for the high volumes of tourists that come in. It reminds me much more of a European city than Vietnamese, at least in the coastal area I was staying. The prices are higher and there are a lot of chain shops and restaurants.
Activities
The main thing I did on my full day in Nha Trang was ride out to Ba Ho Waterfalls, which is out of the city but worth the trip. It's a series of waterfalls that you can swim through and jump off, with an inflatable obstacle course further down the river near the restaurants. The drive out there is also amazingly beautiful, along the coastal road.
Food
Aside from more Banh Mis and the standard fruit, bread and egg breakfast from the hostel, the dinner was in a German owned restaurant called Haus Bremen that served enormous platters of meat: perfect for recovering from a day swimming in the falls.
@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
