I crossed the river from Mexico to Guatemal at Frontera Corozal. It was a lot of fun. When you enter the down you will have to pay 15 pesos to enter because of the ruins, the follow the paved road all the pay to the river. The immigration office is on the right hand side, I think it is a terquoise color and it is gated, ask anyone and they will know. After you stop there dont bother with the people stopping you as you make your way to the river, they charge a lot more then the people at the river, plus you can bargin with them easier once at the river. I pain 200 pesos for me and the bike because I took the first offer when stopped on the road. I worked my way from 800 to 400 to 200 pesos. You can get a better deal at the river. Anyway you will put your bike in the boat cross and it is a little difficult to get it up the other side fully loaded but there will be people there to help and a LASO tied to the front of the bike with someone pulling is a great idea. Once you are up the bank head south to Bethel about a 20 minute ride. The town on the other side is no place I wanted to hang out. Once you come to the intersection at the end of the road stay STRAIGHT/ LEFT dont go RIGHT. The immiration office is on the left, the only building there, you cant miss it. If you see a lot of houses, stores and people turn around you went into Bethel and the immigration office is the other way. You can exchange pesos and dollars at the hut next to the immigration office too. If the lady that owns it isnt there then ask if you can meet her on your way to Flores, we did and it worked great. The officer in the immigration office speaks English very well and it was only $5. The whole crossing was exciting and easy. The road to Flores was rough dirt but fun. I had to cross some flooded parts about halfway to my knees but it was fun.
If you need anymore information let me know I highly recommed this crossing.
