The best area to stay in Frontera Corozal is right along the Usumacinta River, near the main pier and the embarkation points for the Yaxchilan ruins.
This small village is primarily a gateway to the ancient Mayan city of Yaxchilan, accessed by boat. Most accommodation options are concentrated along the riverfront or a short walk inland from it. You'll find a few local eateries and shops clustered around the main road that leads down to the river.
For couples and adventurers keen on exploring Mayan history, staying here is incredibly convenient. You'll be metres away from where the lanchas (small boats) depart for Yaxchilan, allowing for early starts to beat the crowds and enjoy the ruins in cooler temperatures. It's also a good base for exploring the surrounding Lacandon Jungle.
Families will find the riverside area practical as well. The compact nature of the village means everything is within easy reach, and the experience of staying close to the river adds to the adventure.
