Great half day away from the city. Enjoyed the boat tour with visits along the central region of the canal to the monkey islands. The white faced monkeys were the friendliest climbing onto boat to enjoy offered grapes and small peanuts out of our hands. Howlers stayed up in trees as a group and shouted their territorial howls at the boat below. Nice small crowd 3 tourists and 2 guides on one boat. Very pleasant morning. Path trail was different and not difficult for an older traveler like myself.
