Comitan is a pleasant somewhat colonial style city that can be a nice alternative to San Cristobal de las Casas. It has a large section of the city in colonial style, several nice plazas with beautiful churches. It is a good launching off point for a number of sites in Chiapas.
There are plenty of restaurants around the main plaza opposite the church. If you want cheaper food you can find some basic tacos etc in the market (walk past the the church in the main square on the left side and the market will be on your right). There are also a few small street vendors around for snacks like tacos, corn on the cob etc.
There are two budget hotels with (very) basic rooms with shared bathrooms located on the same street as Posada Las Flores for M$70.00. One is called Posada Panamericana and is nearest central park. The one nearest Las Flores was noisy and the bathrooms were in disrepair.
OCC and several private mini-bus operations service surrounding locales, including the Mexican-Guatemalan border and San Cristóbal de las Casas. Their terminals are located on Boulevard Belisario Dominguez Sur. To get to the jungle lake of Laguna Miramar from Comitan it is necessary to take a colectivo to the small town of Las Margaritas from where there is a second colectivo to San Quentin (6 hours). It is a 1 km walk from San Quentin to the village of Emiliano Zapata from where you can hire a guide to take you throug the Lacondon jungle to Laguna Miramar.
