Tulum -> Livingston

I haven't heard of any regular boats on that route. You would have to charter a boat -- easy but expensive.

Is there a boat or an easy way without entering Beliz?

Not that I'm aware of. How much time do you have to get to Livingston?
Your looking at 1-2 nights for this trip, a couple ways to do a cool trip, would need 4-5 days though.

No, there is no boat. You would need to bus to Belize City and then on to Punta Gorda, where you can get water taxis to Livingston or Puerto Barrios. Alternatively, you could bus to Flores (also via Belize City, but there are direct buses there from Chetumal) and then continue on to Rio Dulce, then take a water taxi through the gorge to Livingston.

The other one would be Palenque- Tikal- Rio Dulce- Livingston, probably a more interesting trip, depending what you're into. Any particular reason for wanting to dodge Belize?

I got to Livingston by flying to Guat city fromCancun and catching a bus there to Puerto Barrios and the a boat there to Livingston. Interesting funky place. Photos on wolf calls,com

avoid to pay the entryfee 8-);

Dear all, thank you so much for your replies! As I have only 35 days for my trip 8-)), and like to have as much as possible including time for snorkeling and may be one ore two beers at the beach, dont like to waiste time.
As I leave on the 7.12.2016 I have to bear in mind that the 24.12. as well as the 31.12. is included, and the smaler Hotels / hostels are quite full at this time.
It looks like, that I will be on 24.12. in Celestún, and 31.12. in Livingston or Tulum, and like to make a reservation for this periode in advance.
What would you recommend to stay for 31.12.?

Places I like to visit:
Antigua
Atilan – San Pedro
Chichicastenango
Coban
Laquin - Semuc Champey
Tikal
Palenque
Celestún
Merida
Tulum
Rio Dulce
Livingston
Quiriguá
Copán – Honduras
Monterico

What do you think? Is it possible, or more or less a nightmar ;-)

Thank you so much for your help.

Christmas time means higher prices and required stays. Also if you do go thru Belize you will be hit up for a Mexican exit fee which is illegal and huge fees to exit Belize. Not to mention Entry fee. All of Mexico goes to the beach at christmas time so be ready as some places sold out already I have been told. No one heads to Europe anymore so huge amounts of folks from all over now going to Mexico and points south in Central and South America..

Omg, that sounds horrible. Come to Europe! Please!
Thanks a lot For your help!
