'Taster' riding lesson near north London for a 5-year-old?

[FaintlyMacabre]

Hello, could anyone recommend a good school in/near north London which does taster lessons for young children? My DS1 has expressed an interest in riding but I am clueless! I've been looking at schools in the Enfield area but not sure how to tell which to go for.

If anyone knows one that does pony rides for under 5s as well that would be great- his 3-year-old brother is bound to want to have a try too!

Many thanks for any suggestions.

The only other place I can think of is belmont in Mill Hill, but I'm not sure what they offer. Trent Park used to be very nice, but I havent been there for years.

Thanks very much, I'll see which of those is easier to get too! Fingers crossed he doesn't then ask for a pony of his own- don't think our landlord would be too pleased!
