Our family (parents, 14 year old son) did two tours with Pacz: Xunantunich and ATM. Both were excellent. Our guide for ATM was Oscar. He was knowledgeable, friendly, and professional. The tour was challenging, and he successfully guided 8 guests (all with different ability levels) through the day. Our Xunantunich guide was Jonathan. He was informative about Mayan history and culture, enjoyable to be around, and allowed us plenty of time to just take in the sights. Overall, both tours were great experiences.

Went with Pacz Tours for the ATM Tour. We were picked up from the San Ignacio Hotel. Rates were fair and comparable to the other tour companies (I negotiated a bit, though we were in Belize in the off season July). It was just the two of us and our guide, Oscar. He was professional, knew the cave well, and kept us safe!

This tour is intense, fun, and doable if you are able to climb and swim and also sometimes climb with only socks on. You need water shoes for this, and I don't recommend Keens, because they are terrible shoes, and little pebbles and rocks get under your feet, and the water stays there, and then it's just slopping around as you walk, and is slippery and you will fall. I recommend cheap Amazon hiking water shoes with little holes at the bottom to let the water drain. I also recommend a water shirt.

The cave is exciting. Where else will you see skeletal remains of Mayan sacrifices? Sadly no photos, no cameras, no pictures. So just word of mouth. But in reality, some of the climbing is a bit hairy, and I can't even imagine taking a camera or phone with me. You will fit through tight spaces, water will be up to your neck, you will think you are almost done, but will then do a lot of climbing with only your socks on. You will climb up a ladder deep in the cave.
Bring a change of clothes and a towel.
Lunch is provided and was honestly, pretty good!

This is a once in a lifetime trip. Maybe it won't be around forever? Who knows? Go while you're young and mobile.
As you are deep inside, and it is dark you can't help but imagine what it was like when the Mayas were there.

Highly recommend, Highly recommend Pacz Tours too!

We did the Lamanai tour and it was unbelievable! They offered pick up at our hotel in San Ignacio and our driver Justin was THE BEST. He said he wasn’t a guide but his knowledge of the area said otherwise! He had so many great facts to share on the driving portion of the trip. After the trip was over and he was driving us back he even kindly offered to take us to a market to pick up some food for our hotel stay. He was the sweetest and gave us some mangoes as well. Truly a thoughtful and great guy all around.

For the tour our guide’s name was Eddy and he was an excellent boat driver and guide for Lamanai. He knew so much and was happy to share his knowledge with us. The boat ride is pretty much another tour added on for the price of one. Lamanai is a bit out of the way from San Ignacio but was well worth the trip.
