Your posting makes me cry.
Before this pandemic that would be something I might be doing or should be able to do.... Sigh
Anyway thanks for reminding me how it used to be.
"so will Malaisia"
Your crystal ball is better than mine! We don't expect any change until next year 2022
I agree with PSS.
It's all very well other countries getting significant proportions of their population vaccinated, but it doesn't mean that, once vaccinated, people will/should be allowed to visit countries - like Malaysia and Thailand - who have done such an impressive job of keeping infection levels low. The corollary of this is these countries don't have the same urgent imperative (at least from a public health perspective) to vaccinate quickly and therefore immunity levels will be low for some time.
Permitting (vaccinated) people from other countries to visit - vaccination reduces, but does not eliminate the potential to transmit the virus - these 'immunity vacuums' could have dreadful consequences.Edited: April 07, 2021, 6:11 pm
Agree with PSS & Whyone - not anytime soon.
I have done this trip. You can (normally) get minivans from Georgetown or up at the border.
Right now, I suggest just planning.
I have done that trip, or very similar trips, in both directions a few times. Sometimes by a train bus combo and also by train and boat. Seat61 is a great resource for planning such trips see https://www.seat61.com/Malaysia.htm#Singapore_-_Kuala_Lumpur_-_Penang_-_Bangkok
You can go most of the way be train pretty easily, it limits your stopping off opportunities but is more comfortable. Once we did by using ferries between Penang and Langkawi and Koh Libong just south of Phuket, though that would be possible in 3-4 days you would want to take longer. The seascapes are wonderful along the way. By train, Ipoh is worth a stopover as is Penang. After crossing the bore at Pasar Bedang I feel it is just better to stay on the train though I do like" small town Thailand”. do check the border crossing times as I don’t think the opening times on both sides necessarily tie up and you could end up staying overnight in a not very interesting border town.
I agree with Crellston. Plenty of places to see on the way up to Thailand. I'd also head to Penang - a Malaysian must see in my opinion. From then either up to the border (train or bus) or if you want to do it quickly. Otherwise take a ferry or cheap flight to Langkawi. Then ferry to Satun in Thailand and minibus or regular bus up to Phuket.
Without knowing budget, number of people, age, likes, etc can only give general advice. I've travelled many times between Penang, Langkawi Kuala Perlis and Satun and some of it is certainly worth seeing.
Finally and unfortunately, I wouldn't be planning any cross border travel for a while. If you manage to get into any country, then you will probably have to stay there until you leave to go home..............but please dream on, its all we have at the moment.
