I highly recommend exercising prior to the trip so you can hike up through the lava rocks and up to the crater. Be sure to bring some water and snacks as the hike can be hours long but worth while during the entire journey. Also have solid comfortable shoes and be sure to tighten them on the way up. On the way down from the volcano be prepared to get lava sand inside your shoes and socks. This is an all day trip and the sun can be tough so have some type of head gear.
After the volcano y recommend horseriding to the old town (San Juan). The entire tour can be arranged by the tour guides at the entrance to the town of Angahuan.
The tour may sound expensive but as my tour guide Benito stated, the money goes to help 4 families in town. Benito, who's 60 but in amazing shape did not struggle during the hike, yet my 32 year old body struggled just to make it to the base of the volcano. Once at the crater, the scenery was mesmerizing and at my next trip I plan to spend the night up there.
