The sanctuary is about an hour outside the city off the beaten path so we ended up taking a tour. We spent about $60 USD per person and it was just our party but they drove us to and from setting us up with a tour guide at the sanctuary that took us out into the rainforest and to experience the howler monkeys in their natural habitat. If you do go make sure you wear pants, long sleeve shirt and closed toe shoes. Their is the possibility of rain and you definitely will encounter insects especially mosquitoes.

No they don't

In general, you tip 10% in Belize. The average Belizan makes $1.50 USD per hour. I'm a generous tipper and gave 40 belizan dollars. The guide was surprised I tipped so much. I'd say probably 10 Belizan dollars would be ok though.

Not difficult to find the place. But don't stop a t place about 1 km before the community baboon sanctuary. Finding your way in the nearby village of Burrell Boom can be e bot confusing. When you get there, the will assign you a guide. They work in a certain order, so nothing to choose. We went to the baboons twice, had differrent guides but both were OK.
