Conditions are good in Revy in April. Powder is hit and miss. Revy is not for everyone. Carry an extra $500 and a cell phone. Chopper is the only way to get out if you wreck, and you can wreck at Revy. Degree of difficulty is high and spring riding will get you places you don't want to be. There are juicyer spots about the same distance. I'm 15 hours from REvy, 14 from Cooke, 11 from Buck Creek and 12 from West Y'stone. The Trans Canada highway from Banff to Revy is also not for everyone.
Buck Creek in the Gallatins is big meadow riding and very user friendly. Great motel right at the trail head. You can rent cats near there. Trails with food, fuel, meadows and a some climbing is best at West Y'stone and you can rent enything there. Steeper and deeper is good at Cooke City. Ride right to the motel door. Everything for rent. Mt. Jefferson in Idaho is close to West Y'stone. It's very challenging. Hope this helps you. Have a great holiday.
