You can reach Lampi either from Myanmar or from Thailand.
From Myanmar you can take a local flight from Yangon to Kawthaung (duration approx. 3 hours, with stops in Dawei or Myeik.. Cost is approx. US$250-300).
At Kawthaung you will embark on your pre-booked tourist boat that will take you to Lampi.

You will need a valid tourist visa for Myanmar. You can organise an eVisa (visa on arrival) before you travel to Myanmar at http://evisa.moip.gov.mm or by contacting the Myanmar Embassy in your home country. Your travel agent can also help arrange your visa.
In order to access Lampi, special permits need to be arranged for you by a tour agent. You should book your tour through a licensed liveaboard tour operator at least 2 weeks in advance in order to obtain the travel authorisation in time for your trip.

The local currency is the Myanmar kyat. No other currencies are accepted in the Myeik Islands and Lampi Marine National Park.
There is a bank in Kawthaung that has an ATM and can exchange currency – including USD to kyat. The bank is located on Bo Gyoke Rd, near the Kawthaung Motel.

The best season to visit Lampi park is from October to May during the dry season.
