We took 2 inland trips with Tanisha Tours. The Lamanai trip was run by Daniel Nunez & his knowledge of flora, fauna & the Mayan culture is amazing. We talked to others who went with other operators & they reported that they spent barely 1/2hr. on the actual tour of the ruins. We were there for 1 1/2hrs. & left with a broad knowledge of the Mayans & of Lamanai. The lunch was great, too!
We also did a zipline/Belize Zoo tour that was very well run. Our guide, Randy had a wealth of knowledge about his country & was easy to understand.
Go with Tanisha -- they give great value for the money!!
