Pacific beaches
Within 10-15 minutes by taxi are some of Nicaragua's lightly trod beaches. Las Peñitas is convenient but known for its surfing and mellow vibe. Poneloya is also a close beach. Taxis should run about 150-200 Cordobas per person but the bus station in Leon also has hourly buses. Remember: Strong currents off sections of Nicaragua's Pacific coast have resulted in a number of drownings. Powerful waves have also caused broken bones, and sting ray injuries are not uncommon at popular beaches. Warning signs are not posted, and lifeguards and rescue equipment are not readily available.Definitely make time to surf Cerro Negro. Support Quetzaltrekkers (http://www.quetzaltrekker...), a volunteer organization where all profits go to streetkids; be prepared to leave at 8AM and return at 2:30pm. They also offer many other hikes. Tierra Tours, located 1.5 blocks N of La Merced is a great alternative US$28. Fun guides and ac transport!
Also, a must do is Hervidores San Jacinto. Catch a bus at the terminal or take a taxi, round trip for C$300. Entrance is C$20 and you'll be hooked up with one of the local kids/guides. They are really nice and a must. Be careful to pay attention where they walk, as you will be walking just above thermal activity. As I read somewhere, "It's like a mini Yellowstone, without the fences."
