When visiting Cozumel in 2026, the primary concerns are moped safety and environmental protection. Rental mopeds are a popular way to see the island, but the roads can be slippery, and local traffic can be unpredictable; tourist accidents are common, so helmets are non-negotiable. Environmentally, you must be careful to use biodegradable, reef-safe sunscreen, as standard chemicals are banned in the Cozumel Reefs National Marine Park to protect the delicate coral. Be wary of "Time Share" touts at the cruise piers who offer "free" tours that result in high-pressure sales pitches. Additionally, while the island is generally safe, avoid drinking the tap water, and always confirm the price of a taxi before you get in, as they do not use meters. Finally, stay away from the "ironshore" (jagged limestone) edges of the beach without shoes, as they are razor-sharp and can cause significant cuts if you slip.
