volcano spits lava on a regular basis and - on a clear night
- puts on a terrific fireworks show for lucky visitors and
residents of la Fortuna.
Arenal is the most shapely and lively of Costa Rica's 300 volcanoes, acting as the centrepiece for La Fortuna's tourist trade. The dry season offers your best chance of the rare sight of magma flow or a mini-eruption.
The volcano's base area is a fascinating mass of magma caves; the best route to the base is via a forested path from Tabacon Resort. There are hot springs and cold drinks not far away for pure hedonistic viewing.
Arenal is some way north of San José but two other active volcanoes are closer to the capital and can be visited on day trips - Irazu in the Central Valley and Poas on the Northern Plains with its iridescent crater lake. Both of these are possible to approach much closer than Arenal.

La Fortuna (La Fortuna de San Carlos) offers plenty of tourist excursions and activities when Arenal volcano is not in entertainment mode. Hiking, biking, caving, visiting the Catarata de La Fortuna (a 70m waterfall) and slumping in beautifully designed natural hot pools, for a start.

A thermal spa supplied by warm, mineral volcanic springs is a must-do after a hard day's hiking or other activities, but this is not the place for it, unless you fancy being boiled alive. The Arenal area in particular is packed with superb, beautiful spas and layered pools spectacularly configured into both natural and stylish-but-unnatural environments.
These hot springs come from underground water that is heated by volcanic vents and forced upwards toward the surface passing through mineral deposits and gases which dissolve in the water. Cloudy pools have high levels of minerals dissolved in them whereas clearer pools have roughly the same mineral content but they are less dissolved.
