So here are mine, from my experience of travelling this year:
Vientiane is the capital of Laos, not exactly a secret, but often overlooked and quickly passed through. A city with a desire to develop is what I found, the centre has modern cafès serving fantastic French food, inexpensive guesthouses, a long religious history and there is a strong sense of future about the place.
Sandakan is far east on Malaysia’s half of Borneo Island and was a strong role for the Japanese during WW2. It’s developed yet keeps its heritage almost untouched, hosts a world class orangutan rehabilitaion centre, beautiful countryside and has excellent food everywhere.
Labuan Island, Malaysia
The connecting island between Kota Kinabalu in Malaysia and Brunei is often quickly passed through, but this tax free island is a great place to walk about, get some good food and cheap alcohol for a party on the beach.
