I took a weekend trip to Volcan Masaya, an active volcano. It's pretty cool as you can walk right up to a massive, smoking crater which native people once chucked human sacrifices into to appease the spirit residing inside. There was a small eruption in 2002, sending smoldering boulders 500m into the air and crashing down in the parking lot, damaging cars and narrowly missing people. Neat!
Instead of heading straight back to Granada, I decided to spend the weekend enjoying the fresh-ish waters of Laguna da Apoyo, a wonderful swimming spot nearby. There, I dived, swam, and floated my way to total relaxation. Saturday evening was spent learning Swedish drinking games supplemented by hearts and rum.

Oh yeah, and apparently there were some bad local guys hanging out on the diving platform sniffing glue and offering joints, which I didn't see, but upset some of the other guests. The glue sniffing part, not the joints. Though who really wants to smoke joints with dudes who are sniffing glue? Obviously there would have been some girls around in wet t-shirts too, since it's right on the lake's edge.
