Here's one i highly recommend: Mt Tiede (~ 3,500m) in Tenerife, one of the Canary Islands, which makes it a good trivia question since it's technically the highest peak in Spain (which i would have guessed is in the Sierra Nevadas or the Pyrenees to the East). Tenerife is easier to get to than you might think, it's about a 3.5 hr flight from London, and among that city's airports (Luton, Gatwick, Heathrow, et al) dozens of flights to Tenerife each day. According to the Lonely Planet guide, Mt Tiede is the real deal--an active volcano that last erupted near the start of WW I. There is a very high fence around the caldera. The can walk to the summit via a well-worn switchback (zig-zag) path that's never very steep. It took us all morning, starting at dawn; we never saw another person, then at the summit, a large crowd of tourists standing around, freezing waiting for the next cable car to take them back down. You can see from the summit eg, Grand Canaria.
