Orange Walk is the main town in northern Belize, in the heart of sugar cane country. It's an agricultural and commercial hub rather than a tourist attraction, but it's the starting point for one of the more rewarding day trips in the country: the boat trip up the New River to Lamanai.
Lamanai is among the most atmospheric Maya sites in Belize — temples rising out of dense jungle beside a lagoon, with wildlife (crocodiles, monkeys, toucans) often visible along the river route. The boat journey takes about 1.5 hours each way, and tour operators in Orange Walk run regular trips. Lamanai has occupation evidence spanning over 3,000 years, and some temples were still in use after the Spanish arrived — making it unusual in Maya archaeology.
Orange Walk is easily reached by bus from Belize City on the Northern Highway (about 1.5 hours).
