Vinpearl Land
If you sit on the beach, you'll notice a sign across the water that says "Vinpearl." It's actually an amusement park and resort island that's quite popular. To access the park, you'll need to take the cable car, that owns the Guinness world record for longest sea-crossing cable car system at 3,320 metres.
The park costs 600,000 dong to access, which includes the cabe car ride. It has rides, a water park, aquarium and shows. It's perfect for the family or if you're a kid at heart. Note that the water park closes at 5:30 p.m., so head there first.
Po Nagar Cham Towers
Located within Nha Trang, and potentially walkable (depending where you're staying), are these four brick towers built by the Cham civilization. You can enter the towers, but make sure to dress appropriately - shoulders and knees covered. There's an entrance fee of 22,000 dong.
Where to Eat
Hai San (Seafood) Restaurants
If you walked down the street by the beach, you'll notice a bunch of restaurants selling live sea creatures from eel and shrimp to oysters and clams. It's priced by weight, so you can pick and choose a variety of options. Just be careful as we've heard of people upping the price when you pay. We heard the best restaurants are on the other side of the bridge, close to the fishing villages.
Since it's fresh seafood, it's priced a little high for someone on a budget. But it's definitely cheaper than what you'd pay back home.
