Essentials for Tulum in December

Small backpack or beach bag
Ideal for carrying your daily essentials – water, sunscreen, a book, and a cover-up – whether you're at the beach or exploring.

Great for navigating rocky cenote entrances and protecting your feet while exploring underwater caves.

Cash is King (sometimes)
While many places accept cards, smaller establishments, street vendors, and some eco-parks might prefer or only accept Mexican pesos. Have some small bills on hand.
Embrace the Eco-Chic Vibe
Tulum is known for its sustainability. Opt for eco-friendly products, reuse your towels, and be mindful of your waste to support the local environment.
Book in Advance!
December is peak season. If you have specific restaurants, tours, or activities in mind, make reservations or book tickets well in advance to avoid disappointment.
Protect Against Mosquitos at Dusk
While not as prevalent as the rainy season, mosquitos can still be active, particularly at dawn and dusk. Apply repellent, especially if you're dining outdoors or near lush vegetation.
