Bonito MS Brazil's São Miguel (St. Michael) Caves are gorgeous, with awesome rock formations and well marked and kept trails. Out of the caving activities in the area, this is the easiest one.

It is nearby Lago Azul (Blue Lake) Cave, so it is often worked in right before or right after that one. It is also an activity that happens even in the rain, often making it a great substitute for Lago Azul (Blue Lake), which may easily shut down for safety reasons.

• When you arrive, turn your voucher in at the front desk (Inside the main building)
• Pay attention to the information on group organization, each group is no more than 15 people
• When it is time to begin, the guide will gather the group to provide more information and lead everyone upstairs, where a video will be shown
• After the video, the guide will hand out helmets, flashlights (If necessary) and make sure everyone's shoes are appropriate and allowed
• Once the group is ready, the nature walk begins on that floor itself, because there is a bridge connecting the building to the trail
• The guide instructs people and keeps the pace slow, so that everyone can take it easy and enjoy the woods
• The cave's entrance is easy and the trail is well marked and kept all throughout
• The guide will show and explain the rock formations and phenomenon present in this side of nature that we may sometimes forget about
• The walk inside the cave eventually ends at the exit, which is not the same place as the entrance, and precedes the return trail
• When you get back to the main areas, be sure to turn your helmet back in
• The pace is slow and relaxed before, during and after the cave, because the guide makes stops to deliver explanations and also give people a chance to take a break

The whole operation usually lasts around 1 hour and 30 minutes, but it may vary due to weather conditions and/or specific group needs.
