Biking Holiday late March/Early April

Southern Spain, Sierra MTB.

I think Basque MTB are active for most of the year too?

Too early for BasqueMTB, unfortunately, would happily go back to them, brilliant setup

Sierra look interesting, although I wasn't that impressed with Malaga when i went there before.

I've not been to Sierra, but a few people I met at The White Room raved about them.

You could look at https://puremountains.com/ . They have dates from early March though April.  I went in October this year and enjoyed it.

If you're thinking of Malaga..

https://earthmtb.co.uk/     Alex is a cracking guide

Thanks both. I'm a sucker for drone footage, that looks ace

North Wales, it will be wet.

Ciclo will be great about then. Still some snow on Valetta, but it'll be about 20C down in Orgiva. Aaron is an awesome guide and has picked up Mark's baton & run with it.

I did Ainsa for 2 weeks at that time of year. 2 very wet days, cold at night, t shirt and shorts during the day. Happily do it at that time if year again. 

I have previously been with Basque in March, just checked their calendar and they start mid April, so if you can wait a week or two. I can thoroughly recommend them having been five times on different trips they offer

Hopefully the Spanish Processionary Caterpillar doesn't bother you at all as they're active at that time of year

No-one mentioned Madeira yet?
Madeira.

Freeride Madeira or Ciclo Montana
