The best way to see the park is to hike the Las Coladas Trail and the El Ceibo Trail as a loop. Las Coladas is one of the top hiking trails in Arenal, taking you through the jungle to the base of the volcano, where you can walk over the old lava fields. The top of Arenal volcano is often covered with clouds, but if you're lucky, the clouds will clear for a nice view of the volcano from the lava fields. El Ceibo Trail starts and ends from the Las Coladas Trail. This loop takes you through secondary forest past a massive 400 year old Ceibo tree for which the trail is named. Take your time on this section of the hike to appreciate the abundance of wildlife and exotic plants. Just be alert at all times while hiking through the jungle, watch for both wild animals and geothermal activity.
