Must stop spot on east side of Guam is First Beach!
It's located after Ipan Beach Park coming from Pago Bay, Route 4.
From Tumon area, it takes about 35 minutes by car.
From Tumon Hotel road, head down southeast on Pale San Vitores Rd toward Marine Corps Drive, when you come to the traffic light between Fiesta Resort Hotel and Pacific Island Club (PIC), take the road up toward to K Mart, then next traffic light turn right and get on Marine Corps Drive and drive down til Hagatna.
When you get to the Paseo Traffic light at Hagatna, drive that Paseo Loop toward to Route 4. Pass the Agana Shopping Center and keep drive Cross Island Road.
You pass the Pago Bay, just keep drive down toward south side.You have lots of sightseeing spots along the way like Pago Bay Overlook, Tagachang Beach, Jeff's Pirates Cove.
If you like golf, there is Country Club of Pacific Guam on the way, too.
After you pass the Ipan Beach Park, here it is!
This beach is also good for picnic and enjoy snorkeling with your family.
Inside reef is always calm and water is very clear also.
You can drive inside close to the beach area.
When we went there, someone was fishing right there as picture above.
Here is a map for coming to here as below...
There are couple ways to drive down but I like the way I mentioned at the beginning.
