Do you think hiking shoes are needed or will teva-type water shoes suffice?
You won’t need hiking shoes. If you are planning on climbing ruins, or exploring the jungle make sure you have tennis shoes, walking shoes with good gripping soles or sturdy shoe-sandals with socks. We do not recommend flip-flops for visiting the ruins. We do recommend any shoes with good soles that will not slip. Occasionally the steps of the ruins can be slippery or footing less secure. You can walk barefoot on the beach unless you plan on going up into the Sian Ka’an where there are many rocky beaches that are fun to explore.
