Before you go

Connectivity

Cell service and internet access are limited in Sian Ka'an, especially in Punta Allen. Download offline maps and inform family of your plans before entering the reserve.

Money

Cash is essential in Sian Ka'an—most establishments do not accept credit cards, Apple Pay, or Google Pay. ATMs are not available in the reserve; stock up on pesos in Tulum before your visit.

Packing

Bring reef-safe sunblock, cash in pesos, sufficient water, and snacks. If visiting during rainy season (June-November), prepare for muddy roads and potential flooding.

Safety

Only reef-safe sunblock is permitted in the reserve. Commercial sunblocks containing chemicals that harm coral are banned. Purchase reef-safe options in Tulum or resort areas before entering.

Transport

Combis run from Tulum to Muyil-Chunyaxche (M$80, 07:00-00:00, about 1 hour). The road to Punta Allen is 45 km of rough dirt road; allow 3 hours from the Mayan Arch entrance. A 4WD vehicle is recommended during rainy season.

Weather

Hot and humid year-round with cooler nights. Hurricane season runs June through November. Sargassum seaweed regularly washes ashore on Caribbean beaches—check conditions before visiting.
