Volcán Santo Tomás is one of two long-dormant stratovolcanoes (the other being Volcán Zunil) located south of the ever-popular Fuentes Georginas hot springs. Combined, the two 4.5 km-separated neighbors make for a fantastic multiple-day hike, although if you're just looking to tackle the tallest (by a commanding half-meter) then Santo Tomas is your peak. And despite its relative lack of attention from many travelers, expect the views from the summit of this wooded, 3,542 m massif to be well worth the climb.
Most hikers will start their trek on the trail that begins behind Las Fuentes Georginas (the same trail-head is used for hikes up Zunil as well, so be sure to keep south when it splits at the sawmill to stay on course). It's a fairly strenuous 5-6 hour journey that ascends through Western Guatemala's sub-tropical rain forest, pine forest and eventually a shrub-covered peak with fantastic views of the Xela Valley and Atitlan in the distance. If you want to take your time and get a 2-3 day hike out of the deal, try your hand at the Alaska Route, which will guide you along the Zunil Ridge to its summit and then on to Santo Tomas. Camping is allowable pretty much anywhere along the way, and whichever trail you choose, you'd be wise to end off the excursion with a relaxing dip in the hot springs below. We've provided info on everything you'll need, so get your route (and warm clothes) ready and enjoy one of the country's less-frequented volcano experiences.
