We did the Jungle Hike excursion, booked through
DCL. We were picked up as a group and taken to a small bus. It was air conditioned and nice. The ride tok about 30 minutes and it was really interesting to see the island off the main port area. The ranch where you hike is right beside San Gervasio (sp). Actually San Gervasio used to be part of this ranch. They have lockers for you to use and bathroom facilties that are ok, nothing fancy. They have back packs with snacks/water for you to use or you can use your own. They even had some walking sticks you can borrow.
This ranch does bike tours, 4 wheeler tours and hiking tours. The terrain is pretty rocky but there are very few hills but there is a TON of dust if it's dry. If you 4 wheel, you will get absolutely filthy--but it looked liked fun! They have nice paths and we were taken to 2 ruin sites. Unlike here in the US they let us walk all over them, not sure this is a good idea really. Iames or James gave us our tour and he did a great job talking about the Mayans.
We stopped at one ruin site for snack. They had a cooler with Cokes and Sprites (so yummy in Mexico) and there were a lot of snacks in our bag. Cheetos, crackers, cereal bar, banana, some cupcakes with no icing that remind me of pound cake...plenty to eat. We took the extras back with us. Just remember you can't bring the banana back on board the ship!
After we hiked back to the locker area, we boarded the bus back to the port. They let us out in the parking lot across from Margaritaville which is a couple of blocks from the ship. We had lunch there and it was good. They had a great band playing. My only concern was the ice in the drinks, but we had no problems and everyone eating there were tourists so I figured it was ok.
I would highly recommend this tour. It's too rocky for a stroller but the terrain is moderate. No one is our group had trouble.
